2.Requires 5 dB 1550 nm fixed loss attenuator for < 20 km. Attenuator is available as a spare. The part number is WS-X6K-5DB-ATT=.

3.Links longer than 30 km are considered engineered links.

GBIC Module Cabling Specifications

Table B-6provides cabling specifications for the 1000BASE-X interfaces on the Gigabit Interface Converter (GBIC) modules installed in the Supervisor Engine 2. All GBIC interfaces have SC connectors, and the minimum cable distance for all GBICs listed (MMF and SMF) is 6.5 feet (2 meters).

1.Core size refers to the core diameter. The cladding diameter is usually 25 microns.

2.Cable distances are based on fiber loss.

3.MMF only.

4.Patch cord required.

5.A maximum of 24 1000BASE-ZX GBICs is allowed for each system to comply with FCC Class A regulations.

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).

Console Port Cabling Specifications and Pinouts

The console port, which is located on the front panel of the supervisor engine or route switch processor, provides access to the Cisco 7600 router. The following sections provide information about the console port cabling specifications and the port’s signals and pinouts.
