Required Tools
These tools are required to install an OSM in the Cisco 7600 series router or Catalyst 6500 series switch:
•
•
•
Whenever you handle an OSM, always use a wrist strap or other grounding device to prevent electrostatic discharge (ESD). For information on preventing ESD, see the "Preventing ESD" section of the Site Preparation and Safety Guide.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is more likely to occur with the combination of synthetic fibers and dry atmosphere.
Step 1
Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good skin contact.
Caution
Step 2
If cables are connected at one end only, do not touch the exposed pins at the unconnected end of the cable.
Note
Caution
Preparing to Install the OSMs
Warning
Before installing OSMs, you must install the Cisco 7600 series router or Catalyst 6500 series switch chassis and at least one supervisor engine.
For information on installing the chassis, refer to the Cisco 7603 and 7606 Router Installation Guide, the Cisco 7609 Router Installation Guide, or the Catalyst 6500 Series Installation Guide.
The OSMs are Class 1 laser products.

Connector Types
This section describes the types of connectors associated with the OSMs.
SC-Type Connector
Warning
The SC-type connector (see Figure 18) is used to connect the OSMs to optical networks using both multimode fiber (MMF) and single-mode fiber (SMF).
Figure 18 SC-Type Fiber-Optic Connector
LC-Type Connector
Warning
The LC-type connector (see Figure 19) is used to connect the OC-48 DPT/POS, channelized OC-12, and OC-48 OSMs to optical networks using both MMF and SMF.
Figure 19 LC-Type Fiber-Optic Connector
MT-RJ Connector
Warning
MT-RJ connectors provide a high-density optical connection between the OSM and the network. (See Figure 20.) When you are connecting MT-RJ cables to a module, make sure you firmly press the connector plug into the socket. The upper edge of the plug must snap into the upper front edge of the socket. You may hear an audible click. Gently pull on the plug to confirm whether or not the plug is locked into the socket.
Figure 20 MT-RJ Interface Cable Connector
Always make sure that you insert the connector completely into the socket. This step is especially important when you are making a connection between a module and a long distance (2 km) or a suspected highly attenuated network. If the link LED does not light, remove the network cable plug and reinsert it firmly into the module socket. Dirt or skin oils might have accumulated on the plug faceplate (around the optical-fiber openings) to generate significant attenuation, which reduces the optical power levels below threshold levels so that a link cannot be made.
Caution
To disconnect the plug from the socket, press down on the raised portion on top of the plug (releasing the latch). You should hear an audible click indicating the latch has released. Carefully pull the plug out of the socket.

Fiber Interface Specifications
This section describes these topics:
OC-3, OC-12, and OC-48 POS
The specification for optical fiber transmission defines two types of fiber: single mode and multimode. Within the single-mode category, three transmission types are defined: short reach, intermediate reach, and long reach. Within the multimode category, only short reach is available.
Table 3 lists the specifications for OC-3, Table 4 lists the specifications for OC-12 OSM interfaces, and Table 5 lists the specifications for OC-48 OSM interfaces.
Gigabit Ethernet
Table 6 provides cabling specifications for the 1000BASE-X interfaces, including the Gigabit Ethernet GBIC interfaces. The minimum cable distance for all GBICs listed (MMF and SMF) is 6.5 feet (2 meters).

4 ANSI/TIA/EIA-568-A specifies that the nominal "mode field diameter" shall be 8.7 to 10.0 microns with a tolerance of +/- 0.5 microns at 1310 nm.
5 You can have a maximum of 24 1000BASE-ZX GBICs per system to comply with FCC Class A.
6 Dispersion-shifted single-mode fiber-optic cable.
7 The minimum link distance for ZX GBICs is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without attenuators, the minimum link distance is 24.9 miles (40 km).
Patch Cord
Warning
The mode-conditioning patch cord (Cisco product number CAB-GELX-625 or equivalent) prevents overdriving the receiver for short lengths of MMF and reduces differential mode delay for long lengths of MMF.
Note
Note
Figure 22 shows a typical configuration using the patch cord.
Figure 22 Patch Cord Configuration
Patch Cord Installation
Plug the end of the patch cord labeled "To equipment" into the GBIC. (See Figure 23.) Plug the end labeled "To cable plant" into the patch panel. The patch cord is 9.84 feet (3 meters) long and has duplex SC-type male connectors at each end.
Figure 23 Patch Cord Installation
Differential Mode Delay
When an unconditioned laser source designed for operation on an SMF cable is directly coupled to an MMF cable, differential mode delay (DMD) might occur. DMD can degrade the modal bandwidth of the fiber-optic cable. This degradation causes a decrease in the link span (the distance between the transmitter and the receiver) that can be reliably supported.
The Gigabit Ethernet specification (IEEE 802.3z) outlines parameters for Ethernet communications at a gigabit-per-second rate. The specification offers a higher-speed version of Ethernet for backbone and server connectivity using existing deployed MMF cable by defining the use of laser-based optical components to propagate data over MMF cable.
Lasers function at the baud rates and longer distances required for Gigabit Ethernet. The 802.3z Gigabit Ethernet Task Force has identified the DMD condition that occurs with particular combinations of lasers and MMF cable. The results create an additional element of jitter that can limit the reach of Gigabit Ethernet over MMF cable.
With DMD, a single laser light pulse excites a few modes equally within an MMF cable. These modes, or light pathways, then follow two or more different paths. These paths might have different lengths and transmission delays as the light travels through the cable.
With DMD, a distinct pulse propagating down the cable no longer remains a distinct pulse or, in extreme cases, might become two independent pulses. Strings of pulses can interfere with each other making it difficult to recover data.
DMD does not occur in all deployed fibers; it occurs with certain combinations of worst-case fibers and worst-case transceivers. Gigabit Ethernet experiences this problem because of its very high baud rate and its long MMF cable lengths. SMF cable and copper cable are not affected by DMD.
MMF cable has been tested for use only with LED sources. LEDs can create an overfilled launch condition within the fiber-optic cable. The overfilled launch condition describes the way LED transmitters couple light into the fiber-optic cable in a broad spread of modes. The generated light that shines in multiple directions can overfill the existing cable space and excite a large number of modes, similar to a light bulb radiating light into a dark room. (See Figure 24.)
Figure 24 LED Transmission Compared to Laser Transmission
Lasers launch light in a more concentrated fashion. A laser transmitter couples light into only a fraction of the existing modes or optical pathways present in the fiber-optic cable. (See Figure 24.)
The solution is to condition the laser light launched from the source (transmitter) so it spreads the light evenly across the diameter of the fiber-optic cable making the launch look more like an LED source to the cable. The objective is to scramble the modes of light to distribute the power more equally in all modes and prevent the light from being concentrated in just a few modes.
An unconditioned launch, in the worst case, might concentrate all of its light in the center of the fiber-optic cable, exciting only two or more modes equally.
A significant variation in the amount of DMD is produced from one MMF cable to the next. No reasonable test can be performed to survey an installed cable plant to assess the effect of DMD.
GBIC Installation
The GBIC is a hot-swappable input/output device that plugs into a Gigabit Ethernet port, linking the module port with the fiber-optic network.
GBIC Models
GBICs are available in the three optical models listed in Table 7. The three optical models differ in the distance that light can be sent through a fiber-optic network. These GBICs are available in the two physical models shown in Figure 25.

A copper GBIC, the WS-G5483, is available. The WS-G5483 provides 1000BASE-T full-duplex connectivity between the GBIC-compatible modules, supervisor engines, and the network up to a distance of 328 feet (100 m). See Figure 26.
Figure 26 Copper GBIC (WS-G5483)
Additionally, there are 32 fixed-wavelength GBICs that support the International Telecommunications Union (ITU) 100 GHz wavelength grid.The dense wavelength-division multiplexing (DWDM) GBICs are shown in Figure 27 and listed in Table 8.
Figure 27 DWDM and CWDM GBICs
Finally, there are eight coarse wavelength division multiplexing (CWDM) GBICs A set of eight CWDM GBICs are available for use with the CWDM Passive Optical System. The CWDM GBICs are shown in Figure 27 and listed in Table 9.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
