1. Multimode fiber (MMF) only.
2. A mode-conditioning patch cord is required.
3. You can have a maximum of 12 1000BASEZX GBICs per system to comply with EN55022 Class B regulations and 24
4. The minimum link distance for the GBIC-ZX or WS-G5487 is 6.2 miles (10 km) with an 8-dB attenuator installed at each
5. Contains a Class 1 laser of 1550 nm for 1000BASEZX (extended wavelength) applications.
6. Dispersion-shifted single-mode optical fiber cable.
A mode-conditioning patch cord can be used with the GBIC-LX/LH or WS-G5486 to allow reliable laser
transmission between the single-mode laser source on the GBIC and a multimode optical fiber cable.

GBIC-SX or WS-G5484

The GBIC-SX or WS-G5484 operates on standard multimode fiber-optic link spans of up to 1804 feet
(550 m).

GBIC-LX/LH or WS-G5486

The GBIC-LX/LH or WS-G5486 1000BASELX/LH (long wavelength/long haul) GBIC interfaces fully
comply with the IEEE 802.3z 1000BASELX standard. However, their higher optical quality allows them
to reach 10 km over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.

When using the GBIC-LX/LH or WS-G5486 with 62.5-micron diameter MMF, you must install a mode-conditioning patch
cord between the GBIC 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 GBIC-LX/LH or WS-G5486 and MMF with no patch cord for very short link distances (tens
of meters). The result could be an elevated bit error rate (BER).
