GBIC module, short name for the Gigabit Interface Converter, is a media conversion device between Gigabit Ethernet and fiber optic networks. Thus GBIC modules function is to transform the signals between electric signals and optical fiber signals. GBIC transceiver is hot pluggable, allows a suitably designed enclosure to be changed from one type of external interface to another simply by plugging in a GBIC having the alternative external interface.

GBIC classification is based on its working wavelength, data transmitting rate, working power, and working distance. Generally GBIC fiber optic end the interface is SC type, the laser unit in GBIC module can be 850nm VCSEL, 1310nm FP, 1310nm DFB, and 1550nm DFB. Ingellen provides GBIC transceiver modules, including WS-G5483,WS-G5484,WS-G5486,WS-G5487 and CWDM GBIC. These modules are with 850nm, 1310nm, 1550nm wavelength, 1.25Gbps, 1.0625Gbps data rate, working distance from 300 meters to 80 kilo meters. But how much do you know about CWDM GBIC module?

CWDM GBIC module
The CWDM GBIC module, works at 1.25Gbps full duplex mode, help companies and service providers to set up scalable and easy to deploy Gigabit Ethernet and Fiber Channel service in the networks. The CWDM GBIC modules are plug and play and very simple to use, which do not require configuration. The CWDM GBIC are used in fiber optic network according to IEEE 802.3z standard, it could be plugged into the GBIC ports or slots of router or switch for linking.

There are a wide range of CWDM GBIC available, including CWDM GBIC 1470, CWDM GBIC 1490, CWDM GBIC 1510, CWDM GBIC 1530, CWDM GBIC 1550, CWDM GBIC 1570, CWDM GBIC 1590, CWDM GBIC 1610, these products operate at different working wavelength. Follow is their typical specifications.

CWDM GBIC transceivers Features:
Dual data-rate of 1.25Gbps/1.0625Gbps operation;
18 CWDM DFB wavelengths laser and PIN photodetector for 80km transmission;
Duplex SC optical interface;
Standard serial ID information compatible with SFF-8053;
+3.3V/5Vsingle power supply;
RoHS Compliant;
Operating case temperature: 0 to +70℃.

Cisco GBIC fiber transceiver is an international acknowledged standard as described by SFF Committee in document SFF-8053. They are a series of pluggable Gigabit rate transceivers that can be used on the GBIC ports on the equipment to link with the fiber optic networks. Common Cisco GBIC fiber optic transceivers use dual SC optical fiber interface, which can fit to the GBIC slot on the switches or routers. Cisco CWDM GBIC transceivers work with wavelength from 1470nm to 1610nm, each bear different colors to identify them easily. All theCWDM GBICtransceivers are compatible with IEEE 1000Base-X standards and hot pluggable, easy for deployment and maintenance in Gigabit Networks.

Note:
When install the GBIC modules, please note at the alignment groove at the side of the transceiver, and make sure it fit for the Ethernet interface slot(sometimes you may need to turn it 180 degree to fit for the interface) and try the insertion. More, before you install or remove it, please disconnect all the fiber optic patch cords connected to it.
