GBIC Module and SFP Module Overview

•

GBIC Module and SFP Module Cabling and Connection Equipment

The GBIC module port is a 1000-Mbps optical interface in the form of an SC-type duplex port (see

Figure

Table 6

Gigabit Ethernet devices. Note that all GBIC module ports have SC-type connectors and all SFP ports

have LC-type connectors.

The minimum cable distance for the WS-G5484 or GLC-SX-MM and WS-G5486 or GLC-LH-SM

(multimode fiber [MMF] and single-mode fiber [SMF]) is 6.5 feet (2 m), and the minimum link distance

for the WS-G5487 or GLC-ZX-SM is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of

the link. Without attenuators, the minimum link distance for the WS-G5487 or GLC-ZX-SM is 24.9

miles (40 km).

1. Multimode fiber (MMF) only.

2. A mode-conditioning patch cord is required.

When using the WS-G5486 or GLC-LH-SM with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC module

or SFP module and the MMF cable on both the transmit and the receive ends of the link when link distances are greater than 984 ft (300 m).

We do not recommend using the WS-G5486 or GLC-LH-SM and MMF with no patch cord for very short link distance (tens of meters). The result could

be an elevated bit error rate (BER).

Gigabit Interface Converter (GBIC) Module and Small Form-Factor Pluggable (SFP) GBIC Module Installation Information and Specifications

Insert a 5-dB in-line optical attenuator between the fiber-optic cable plant and the receiving port on

the 1000BASE-ZX GBIC module at each end of the link whenever the fiber-optic cable span is equal

to or greater than 15.5 miles (25 km) but less than 31 miles (50 km).
