The OPT-PRE is equipped with a built-in variable optical attenuator (VOA) that controls the gain tilt and 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 card is designed to support up to 80 channels at 50-GHz channel spacing. The OPT-PRE features include:

• 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)

• MAL for fiber-based DCU

• Amplified spontaneous emissions (ASE) compensation in fixed gain mode

• Full monitoring and alarm handling with settable thresholds

• 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

  Note	The optical splitter has a ratio of 1:99, resulting in about 20 dB-lower power at the MON port than at the COM TX port.

The OPT-BST is designed to ultimately support up to 80 channels at 50-GHz channel spacing. The OPT-BST-E amplifier card is a gain-enhanced version of the OPT-BST card. It is designed to support up to 80 channels at 50-GHz channel spacing. Both the cards are C-band, DWDM EDFA with optical service channel (OSC) add-and-drop capability. When an OPT-BST or an OPT-BST-E is installed, an OSCM card is also needed to process the OSC. You can install the OPT-BST and OPT-BST-E cards in Slots 1 to 6 and 12 to 17.

Note	For OPT-RAMP-C or OPT-RAMP-CE card safety labels, see "Class 1M Laser Product Cards".

The OPT-RAMP-C card is a double-slot card that improves unregenerated sections in long spans using the span fiber to amplify the optical signal. Different wavelengths in C-band receive different gain values. To achieve Raman amplification, two Raman signals (that do not carry any payload or overhead) are required to be transmitted on the optical fiber because the gain generated by one signal is not flat. The energy of these Raman signals transfer to the higher region of the spectrum thereby amplifying the signals transmitted at higher wavelengths. The Raman effect reduces span loss but does not compensate it completely.

When the Raman optical powers are set correctly, a gain profile with limited ripple is achieved. The wavelengths of the Raman signals are not in the C-band of the spectrum (used by MSTP for payload signals). The two Raman wavelengths are fixed and always the same. Due to a limited Raman gain, an EDFA amplifier is embedded into the card to generate a higher total gain. An embedded EDFA gain block provides a first amplification stage, while the mid stage access (MSA) is used for DCU loss compensation.

The OPT-RAMP-CE card is a 20 dBm output power, gain-enhanced version of the OPT-RAMP-C card and is optimized for short spans. The OPT-RAMP-C and OPT-RAMP-CE cards can support up to 80 optical transmission channels at 50-GHz channel spacing over the C-band of the optical spectrum (wavelengths from 1529 nm to 1562.5 nm). To provide a counter-propagating Raman pump into the transmission fiber, the Raman amplifier provides up to 500 mW at the LINE-RX connector. The OPT-RAMP-C or OPT-RAMP-CE card can be installed in Slots 1 to 5 and 12 to 16, and supports all network configurations. However, the OPT-RAMP-C or OPT-RAMP-CE card must be equipped on both endpoints of a span.

The Raman total power and Raman ratio can be configured using CTC. The Raman configuration can be viewed on the Maintenance > Installation tab.

The features of the OPT-RAMP-C and OPT-RAMP-CE card include:

• Raman pump with embedded EDFA gain block

• Raman section: 500 mW total pump power for two pump wavelengths

• EDFA section:

  • OPT-RAMP-C: 16 dB gain and 17 dB output power

  • OPT-RAMP-CE: 11 dB gain and 20 dB output power

• Gain Flattening Filter (GFF) for Raman plus EDFA ripple compensation

• MSA for DC units

• VOA for DC input power control

• Full monitoring of pump, OSC, and signal power

• Fast gain control for transient suppression

• Low-FIT (hardware-managed) optical laser safety

• Hardware output signals for LOS monitoring at input photodiodes

• Optical service channel add and drop filters

Note	The RAMAN-CTP and RAMAN-COP cards are supported in R9.3.02 and later.

Note	For RAMAN-CTP and RAMAN-COP cards safety labels, see "Class 1M Laser Product Cards".

The single-slot RAMAN-CTP and RAMAN-COP cards support counter and co-propagating Raman amplification on very long unregenerated spans.

The cards manage up to 96 ITU-T 50-GHz spaced channels over the C-band of the optical spectrum (wavelengths from 1528.77 nm to 1566.72 nm). The counter-propagating RAMAN-CTP card is the master unit. The co-propagating RAMAN-COP card is the slave unit and can be used only when the counter-propagating unit is present. The RAMAN-CTP card and the RAMAN-COP card must be installed in adjacent slots for Cisco NCS 2000 Series chassis. However, these adjacent slots must not be used to install two RAMAN-CTP or two RAMAN-COP cards.

The RAMAN-CTP card can be calibrated either manually or using the Automatic Raman Pump Amplification (ARPC) procedure from the Card tab in the Provisioning panel in CTC. When the RAMAN-COP card is used, the RAMAN-CTP card can be calibrated only using the manual option. ARPC is supported only in the NCS Flex package.

The OPT-EDFA-17 and OPT-EDFA-24 cards are C-band, DWDM EDFA amplifiers/preamplifiers with 20-dBm output powers. These cards do not contain mid-stage access loss for a Dispersion Compensation Unit (DCU). The OPT-EDFA-17 and OPT-EDFA-24 cards provide a noise-figure optimized version of the EDFA amplifiers to cope with new modulation formats like PM-DQPSK, which do not need dispersion compensation. To control gain tilt, a VOA is used. The amplifier module also includes the OSC add (TX direction) and drop (RX direction) optical filters.

The OPT-EDFA-17 and OPT-EDFA-24 cards share the same hardware platform and firmware architecture but differ in their operative optical gain range, which is 17 dB and 24 dB respectively.

They support 96 channels at 50-GHz channel spacing in the C-band (that is, 1528.77 nm to 1566.72 nm wavelength range). When an ONS 15454 has an OPT-EDFA-17 or OPT-EDFA-24 card installed, an OSCM card is needed to process the OSC. You can install the OPT-EDFA-17 or OPT-EDFA-24 card in Slots 1 to 6 and 12 to 17.
