6.1  DWDM Card Overview

The DWDM card overview section summarizes card functions, power consumption, and temperature ranges. DWDM cards are compatible with Software Release 4.5 only. They are not compatible with cross-connect (XC), cross-connect VT (XCVT), or cross-connect 10 Gbps (XC10G) cards.


Note Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. The cards are then installed into slots displaying the same symbols. See the "Card Slot Requirements" section for a list of slots and symbols.


6.1.1  DWDM Cards

ONS 15454 DWDM cards are grouped into the following categories:

Optical service channel cards provide bidirectional channels that connect all the ONS 15454 DWDM nodes and transport general-purpose information without affecting the client traffic. ONS 15454 optical service channel cards include the Optical Service Channel Module (OSCM) and the Optical Service Channel and Combiner/Separator Module (OSC-CSM).

Optical amplifier cards are used in amplified DWDM nodes, including hub nodes, amplified OADM nodes, and line amplified nodes. The cards are composed of three main modules: an optical plug-in, a microprocessor, and a DC/DC converter. Optical amplifier cards include the Optical Pre-amplifier (OPT-PRE) and Optical Booster (OPT-BST) amplifier.

Dispersion compensation units are installed in the ONS 15454 dispersion compensation shelf when optical pre-amplifier cards are installed in the DWDM node. Each DCU module can compensate a maximum of 65 km of single-mode fiber (SMF-28) span. DCUs can be cascaded to extend the compensation to 130 km.

Multiplexer and demultiplexer cards multiplex and demultiplex DWDM optical channels. The cards are composed of three main modules: optical plug-in, microprocessor, and the DC/DC converter. ONS 15454 multiplexer and demultiplexer cards include the 32-Channel Multiplexer (32 MUX-O), the 32-Channel Demultiplexer (32 DMX-O), and the 4-Channel Multiplexer/Demultiplexer (4MD-xx.x).

Optical Add/Drop multiplexers (OADM) cards are mainly divided into two groups: band OADM and channel OADM cards. Band OADM cards add and drop one or four bands of adjacent channels; they include the 4-Band OADM (AD-4B-xx.x) and the 1-Band OADM (AD-1B-xx.x). Channel OADM cards add and drop one, two or four adjacent channels; they include the 4-Channel OADM (AD-4C-xx.x), the 2-Channel OADM (AD-2C-xx.x) and the 1-Channel OADM (AD-1C-xx.x). The cards are composed of three main modules: optical plug-in, microprocessor, and the DC/DC converter.

6.1.5  DWDM Card Channel Allocation Plan

ONS 15454 DWDM multiplexers, demultiplexers, channel OADM, and band OADM cards are designed for use with specific channels. In most cases, the channels for these cards are either numbered (1 to 32) or delimited (odd or even). Client interfaces must comply with these channel assignments to be compatible with ONS 15454.

Table 6-9 lists the channel IDs and wavelengths assigned to the DWDM channels.

6.2  OSCM Card

An optical service channel (OSC) is a bidirectional channel connecting all the nodes in a ring. The channel transports OSC overhead that is used to manage ONS 15454 DWDM networks. The OSC uses the 1510-nm wavelength and does not affect client traffic. The primary purpose of this channel is to carry clock synchronization and orderwire channel communications for the DWDM network. It also provides transparent links between each node in the network. The OSC is an OC-3 formatted signal.

There are two versions of the OSC modules: the OSCM, and the OSC-CSM which contains a combiner and separator module in addition to the OSC module. For information about the OSC-CSM, see the "OSC-CSM Card" section. Figure 6-1 shows the OSCM faceplate.

Figure 6-1 OSCM Faceplate

Figure 6-2 shows the OSCM block diagram.

Figure 6-2 OSCM Block Diagram

The OSCM is used in amplified nodes that include the OPT-BST booster amplifier. The OPT-BST includes the required OSC wavelength combiner and separator component. The OSCM cannot be used in nodes where you use OC-N cards, electrical cards, or cross-connect cards. The OSCM uses Slots 8 and 10, which are also cross-connect card slots.


Note Software R4.5 does not support DWDM cards and features in the same node as cross-connect, OC-N, and electrical cards.


The OSCM supports the following features:

OC-3 formatted OSC

Supervisory data channel (SDC) forwarded to the TCC2 cards for processing

Distribution of the synchronous clock to all nodes in the ring

100BaseT FE user data channel (UDC)

Monitoring functions such as orderwire support and optical safety

The OC-3 section data communications channel (SDCC) overhead bytes are used for network communications. An optical transceiver terminates the OC-3, then it is regenerated and converted into an electrical signal. The SDCC bytes are forwarded to the active and standby TCC2 cards for processing via the system communication link (SCL) bus on the backplane. Orderwire bytes (E1, E2, F1) are also forwarded via the SCL bus to the TCC2 for forwarding to the AIC-I card.

The payload portion of the OC-3 is used to carry the fast Ethernet UDC. The frame is sent to a POS processing block that extracts the Ethernet packets and makes them available at the RJ-45 connector.

The OSCM, which resides in the cross-connect slots and follows the ONS 15454 backplane architecture, distributes the reference clock information by removing it from the incoming OC-3 signal and then sending it to the DWDM cards. The DWDM cards then forward the clock information to the active and standby TCC2 cards.

6.2.1  OSCM Card-Level Indicators

The OSCM card has three card-level LED indicators, described in Table 6-10.

Table 6-10 OSCM Card-Level Indicators  

Card-Level Indicators
Description
Red FAIL LED

The red FAIL LED indicates that the card's processor is not ready or that there is an internal hardware failure. Replace the card if the red FAIL LED persists.

Green ACT LED

The green ACT LED indicates that the OSCM is carrying traffic or is traffic-ready.

Amber SF LED

The amber SF LED indicates a signal failure or condition such as LOS, LOF, AIS-L, or high BER on one or more of the card's ports. The amber SF LED also illuminates when the transmit and receive fibers are incorrectly connected. When the fibers are properly connected, the light turns off.


6.2.2  OSCM Port-Level Indicators

You can find the status of the card ports using the LCD screen on the ONS 15454 fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot. The OSCM has three OC3 optical ports located on the faceplate. One long-reach OCS transmits and receives the OSC to and from another DWDM node. Both data communications network (DCN) data and far-end (FE) payload are carried on this link. Two intermediate-reach OC3s are used for DCN extension.

The OSC uses the 1510-nm wavelength and does not affect client traffic. The primary purpose of this channel is to carry clock synchronization and orderwire channel communications for the DWDM network. It also provides transparent links between each node in the network. The OSC is an OC-3 formatted signal.

There are two versions of the OSC modules: the OSCM, and the OSC-CSM which contains a combiner and separator module in addition to the OSC module. For information about the OSCM, see the "OSCM Card" section. Figure 6-3 shows the OSC-CSM faceplate.

Figure 6-3 OSC-CSM Faceplate

Figure 6-4 shows the OSC-CSM block diagram.

Figure 6-4 OSC-CSM Block Diagram

The OSC-CSM is used in unamplified nodes. This means that the booster amplifier with the OSC wavelength combiner and separator is not required for OSC-CSM operation. The OSC-CSM can be installed in Slots 1 to 6 and 12 to 17. If you are planning to use OC-N cards, electrical cards, or cross-connect cards in the same node in a future software release, the OSC-CSM will support this functionality. The cross-connect cards enable functionality on the OC-N cards and electrical cards.


Note Software R4.5 does not support DWDM cards and features in the same node as cross-connect, OC-N, and electrical cards.


The OSC-CSM supports the following features:

Optical combiner and separator module for multiplexing and demultiplexing the optical service channel to or from the wave division multiplexing (WDM) signal

OC-3 formatted OSC

Supervisory data channel (SDC) forwarded to the TCC2 cards for processing

Distribution of the synchronous clock to all nodes in the ring

100BaseT FE UDC

Monitoring functions such as orderwire support and optical safety

Optical safety: signal loss detection and alarming, fast transmitted power shut down by means of an optical 1x1 switch

Optical safety remote interlock (OSRI), a feature capable of shutting down the optical output power

Automatic laser shutdown (ALS), a safety mechanism used in the event of a fiber cut

The WDM signal coming from the line is passed through the OSC combiner and separator, where the OSC signal is extracted from the WDM signal. The WDM signal is sent along with the remaining channels to the COM port (label on the front panel) for routing to the OADM or amplifier units, while the OSC signal is sent to an optical transceiver.

The OSC is an OC-3 formatted signal. The OC-3 SDCC overhead bytes are used for network communications. An optical transceiver terminates the OC-3, and then it is regenerated and converted into an electrical signal. The SDCC bytes are forwarded to the active and standby TCC2 cards for processing via the SCL bus on the backplane. Orderwire bytes (E1, E2, F1) are also forwarded via the SCL bus to the TCC2 for forwarding to the AIC-I card.

The payload portion of the OC-3 is used to carry the fast Ethernet UDC. The frame is sent to a POS processing block that extracts the Ethernet packets and makes them available at the RJ-45 front panel connector.

The OSC-CSM distributes the reference clock information by removing it from the incoming OC-3 signal and then sending it to the active and standby TCC2s. The clock distribution is different from the OSCM card because the OSC-CSM does not use Slot 8 or 10 (cross-connect card slots).

6.3.1  OSC-CSM Card-Level Indicators

The OSC-CSM card has three card-level LED indicators, described in Table 6-11.

Table 6-11 OSC-CSM Card-Level Indicators

6.4  OPT-PRE Amplifier

Optical amplifiers are used in amplified nodes, such as hub nodes, amplified OADM nodes, and line amplifier nodes. There are two forms of amplifiers, the Optical Preamplifier (OPT-PRE) and the Optical Booster (OPT-BST) amplifier. For more information about the OPT-BST card, see the "OPT-BST Amplifier" section. The optical amplifier card architecture includes an optical plug-in module with a controller that manages optical power, laser current, and temperature control loops. The amplifier also manages communication with the TCC2, and operations, administration, maintenance, and provisioning (OAM&P) functions such as provisioning, controls, and alarms.

Optical amplifiers have a linear power feature that enables them to be kept in the constant gain mode if the gain is less than 28 dB. However, for longer span solutions it is necessary to place the amplifier in constant power mode. In constant power mode, automatic power control (APC) requirements change. This is because span loss degradation does not effect the system and amplifiers are not able to automatically modify the output power for variations in the number of channels when provisioning changes and a failure occurs.

Figure 6-5 shows the OPT-PRE amplifier faceplate.

Figure 6-5 OPT-PRE Faceplate

Figure 6-6 shows the OPT-PRE block diagram.

Figure 6-6 OPT-PRE Block Diagram

Figure 6-7 shows the OPT-PRE optical function block diagram.

Figure 6-7 OPT-PRE Optical Function Diagram

The OPT-PRE is designed to support 64 channels at 50-GHz channel spacing, but currently, Software R4.5 supports 32 channels at 100 GHz. The OPT-PRE is a C-band DWDM, two-stage erbium-doped fiber amplifier (EDFA) with mid-amplifier loss (MAL) for allocation to a dispersion compensation unit (DCU). To control the gain tilt, the OPT-PRE is equipped with a built-in VOA. The VOA can also be used to pad the DCU to a reference value. You can install the OPT-PRE in Slots 1 to 6 and 12 to 17.

The OPT-PRE features:

Fixed gain mode with programmable tilt

True variable gain

Fast transient suppression

Nondistorting low-frequency transfer function

Settable maximum output power

Fixed output power mode (mode used during provisioning)

Constant drive current mode (test mode)

MAL for fiber-based DCU

Amplified spontaneous emissions (ASE) compensation in fixed gain mode

Full monitoring and alarm handling with settable thresholds

Optical safety features that include signal loss detection and alarming, fast power down control and reduced maximum output power in safe power mode

Four signal photodiodes to monitor the input and output optical power of the two amplifier stages through CTC

An optical output port for external monitoring

6.13  AD-4B-xx.x Card

The 4-Band OADM (AD-4B-xx.x) card passively adds or drops four bands of four adjacent 100-GHz-spaced channels. Two versions of this card with different part numbers—each version designed for use with one set of bands—are used in the ONS 15454 DWDM system. The card bidirectionally adds and drops in two different sections on the same card to manage signal flow in both directions. This card can be used when there is asymmetric adding and dropping on each side (east or west) of the node; a band can be added or dropped on one side but not on the other.

The AD1B-xx.x can be installed in Slots 1 to 6 and 12 to 17.

The AD-4B-xx.x has the following features:

Five software-controlled VOAs regulate the optical power flowing in the OADM paths.

Output power of each dropped band is set by changing the attenuation of each VOA drop.

The VOA express is used to regulate the insertion loss of the express path.

Internal controlled VOA settings and functions, photodiode detection, and alarm thresholds.

Software-monitored virtual photodiode (firmware calculation of port optical power) at the common DWDM output port.

6.13.1  AD-4B-xx.x Card-Level Indicators

The AD-4B-xx.x card has three card-level LED indicators, described in Table 6-33.

Table 6-33 AD-4B-xx.x Card-Level Indicators  

Card-Level Indicators
Description
Red FAIL LED

The red FAIL LED indicates that the card's processor is not ready or that there is an internal hardware failure. Replace the card if the red FAIL LED persists.

Green ACT LED

The green ACT LED indicates that theAD-4B-xx.x card is carrying traffic or is traffic-ready.

Amber SF LED

The amber SF LED indicates a signal failure. The amber SF LED also illuminates when the transmit and receive fibers are incorrectly connected. When the fibers are properly connected, the light turns off.


6.13.2  AD-4B-xx.x Port-Level Indicators

You can find the status of the card port using the LCD screen on the ONS 15454 fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot. The AD-4B-xx.x has 12 LC-PC-II optical ports: eight for add/drop band client input and output, two for express channel input and output, and two for communication.
