The globalized business world today looks for better communication options. This along with the technological innovations has given rise to use of a number of telecommunication equipments. A transceiver is one such equipment that combines both a receiver and a transmitter sharing a single housing or a common circuitry. Where there is no common circuitry between the receiver and transmitter, the equipment is known as a transmitter-receiver.

The advent of fiber optics in telecommunications has paved way for the use a number of devices running on fiber optic cables. The gigabit interface converter or GBIC is an input/output transceiver. With one end plug into a gigabit Ethernet port or switches, the other end of the transceiver is to connect the fiber optic patch cords and linked to the fiber optic network.  The GBIC modules basically functions to transform the signals between the Ethernet network and fiber optic network. GBIC’s are classified according to its working wavelength, rate of data transmission, power, and the distance.

GBIC transceiver, with its plugable feature facilitates the change of enclosures from one type to another with ease. Other feature, which makes these GBIC transceivers quite sought, is the design, which is very, practical one meant for high performance and point-to-point communication. With an ability to take up to 1.25 Gb/s of bi-directional data link, this hot plugable device has low power dissipation, Low EMI but compatible on an extended power supply of +3.3/5.0 V.

Coarse Wavelength-Division Multiplexing Gigabit Interface Converter or CWDM GBIC as it is commonly referred to in the technical jargon, is a solution, which facilitates a scalable and easily deployable Ethernet and fibre channel services.  This paves way for the companies and service providers to present to their clients a multi service networks with high availability and flexible design.  With two main components-eight different plugable CWDM GBIC’s, Cisco SFP and Cisco multiplexers and demultiplexers, the configuration sounds complex. However, this is a cost-effective solution for adoption in data centers, metropolitan area networks or even within campuses.

The benefits of using CWDM GBIC solution is that being scalable, it helps to transmit eight channels over a single mode fiber. This GBIC transceiver uses a two-path link configuration in ring architecture to avoid fiber cuts. Further, aided by its multichannel architecture and the inherent protection feature of ring architectures, it builds highly available links with the help of redundancy and fail over mechanisms at channel endpoints.
