Four Kinds of Cisco GBIC Transceiver Modules

GBIC is short for gigabit interface converter,it is a media conversion device between Gigabit Ethernet and fiber optic networks, through GBIC transceiver, Gigabit network equipment can directly connect with copper wires, single mode fiber ports or multimode fiber ports. The data transfer rates are one gigabit per second (1 Gbps) or even more.

The Cisco? Gigabit Interface Converter (GBIC) can be a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port using the network. From FiberStore, you can expect a complete array of Cisco GBIC transceiver modules. There are lots of types for GBIC transceivers, including Cisco WS-G5483,Cisco WS-G5484,Cisco WS-G5486,Cisco WS-G5487 and so forth.

Cisco WS-G5483 (Copper) GBIC module:

The Cisco WS-G5483 (1000BASE-T GBIC Transceiver) connects a GBIC port to Category 5 wiring utilizing a standard RJ-45 interface. The most Category 5 wiring distance is 328 feet (100 m).Cisco WS-G5483, also referred to as copper GBIC transceiver, is a great solution for Catalyst switch customers.

Cisco WS-G5484 (short wavelength) GBIC module:

The Cisco WS-G5484 GBIC (1000BASE-SX GBIC Transceiver) runs using legacy multimode fiber (MMF) optic link spans up to 1804 feet (550 m) and also on laser-optimized multimode fiber (OM3) optic link spans approximately 3281 feet (1 km).The 1000BASE-SX is really a short wavelength GBIC module.

Cisco WS-G5486 (long wavelength/long haul) GBIC module:

The Cisco WS-G5486 (1000BASE-LX/LH GBIC Transceiver) fully matches the IEEE 802.3z 1000BASE-LX10 standard. It enables for reaches approximately 6.2 miles (10 km) over single-mode fiber (SMF) and up to 550 meters over multimode fiber (MMF). The long wavelength/long haul GBIC module is Cisco WS-G5486.

Cisco WS-G5487 (extended wavelength) GBIC module:

The Cisco WS-G5487(1000BASE-ZX GBIC Transceiver) is run on ordinary single-mode fiber optic link spans up to 43.5 miles (70 km) long. Link spans of up to 62 miles (100 km) are possible using premium single-mode fiber or dispersion shifted single-mode fiber(premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and fewer dispersion). The GBIC has an optical link budget of 21 dB - the actual link span length is determined by multiple factors including fiber quality, number of splices, and connectors.

When shorter distances of single-mode fiber are utilized, it might be essential to insert an in-line optical attenuator inside the connect to avoid overloading the receiver:

A 5-dB or 10-dB inline optical attenuator needs to be inserted between your fiber-optic cable plant as well as the receiving port around the Cisco 1000BASE-ZX GBIC each and every end of the link whenever the fiber-optic cable span is under 15.5 miles (25 km)

Note:The 1000BASE-ZX GBIC module provide an optical power budget of 21.5 dB. You need to measure your cable plant by having an optical loss test set to ensure the optical loss of the cable plant (including connectors and splices) is lower than or equal to 21.5 dB. The optical loss measurement has to be performed having a 1550-nm light source.
