GBIC is brief for gigabit interface converter,it is a media
conversion device between Gigabit Ethernet and fiber optic networks,
through the GBIC transceiver, Gigabit network equipment
can directly connect to copper wires, single mode fiber ports or
multimode fiber ports. The information transfer rates are one gigabit
per second (1 Gbps) or maybe more.
The Cisco Gigabit Interface
Converter (GBIC) is a hot-swappable input/output device that connects to
a Gigabit Ethernet port or slot, linking the port with all the network.
From FiberStore, we provide a full range of Cisco GBIC transceiver
modules. There are lots of types for GBIC transceivers, such as Cisco
WS-G5483,Cisco WS-G5484,Cisco WS-G5486,Cisco WS-G5487 and so on.
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 utmost Category 5 wiring
distance is 328 feet (100 m).Cisco WS-G5483, also referred to as copper
GBIC transceiver, is a perfect 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 as much as 1804 feet (550 m) and also on
laser-optimized multimode fiber (OM3) optic link spans as much as 3281
feet (1 km).The 1000BASE-SX is a short wavelength GBIC module.
Cisco WS-G5486 (long wavelength/long haul) GBIC module:
The Cisco WS-G5486 (1000BASE-LX/LH
GBIC Transceiver) fully complies with the IEEE 802.3z 1000BASE-LX10
standard. It allows for reaches up to 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) runs using ordinary
single-mode fiber optic link spans approximately 43.5 miles (70 km)
long. Link spans as high as 62 miles (100 km) are possible using premium
single-mode fiber or dispersion shifted single-mode fiber(premium
single-mode fiber includes a lower attenuation per unit length than
ordinary single-mode fiber; dispersion-shifted single-mode fiber has
both lower attenuation and less dispersion). The GBIC offers an optical
link budget of 21 dB - the particular link span length will depend on
multiple factors including fiber quality, quantity of splices, and
connectors.
When shorter distances of single-mode fiber are used,
it might be required to insert an in-line optical attenuator inside the
hyperlink to avoid overloading the receiver:
A 5-dB or 10-dB
inline optical attenuator should be inserted involving the fiber-optic
cable plant and the receiving port around the Cisco 1000BASE-ZX GBIC at
each end with the link whenever the fiber-optic cable span is less than
15.5 miles (25 km)
Note:The 1000BASE-ZX GBIC
module offer an optical power budget of 21.5 dB. You ought to measure
your cable plant with an optical loss test set to ensure that the
optical loss in the cable plant (including connectors and splices) is
less than or equal to 21.5 dB. The optical loss measurement must be
performed with a 1550-nm light source.
