Optical and electrical drivers


Fibre Channel has different options for the driving of the Fibre and for the type of media used. These different FC-0 technology options have different speed and distance abilities.

The following different types of drivers exist:

For the optical drivers and receivers simple devices exists such as lasers and diodes, but also more complex devices that control the transmitted and received power and temperature are available. All those drivers accept the 8b10b coded serial bitstream and convert them to optical and do the reverse for the receiving side.

The electrical drivers and receivers are simple Emitter Coupled Logic, but for some of the media used equalizer circuits are necessary to correct for some of the signal distortion caused by the difference in amplitude loss and propagation delay time between frequency components of the transmitted signal. These equalizer circuits include inductors and capacitors. The data links may be transformer or capacitively coupled to provide common mode noise rejection and ground isolation.

Modules that are compatible with the GBIC specification should be used in products that need a driver that can be interchanged by the user. In this case the user can replace easily broken modules, but he can also change drivers from optical into electrical version, or with ones with different connectors. 


Optical drivers and receivers exist from the following manufacturers: Electrical drivers are made by

Copperhead ® transceivers

The COPTR 133 to COPTR 1062 series deliver Fibre Channel speed to the workstation over IBM Type 1 Shielded Twisted Pair (STP) copper cable. Technitrol's transceivers are designed to be completely interoperable with existing ECL fiber transceiver drivers. The Fibre Channel transceivers incorporate the silicon and magnetics necessary to drive over 100 meters of Shielded Twisted Pair cable. Video and Mini- coax versions are also available. The Copperhead ® transceivers are packaged in a Surface mount Gull Wing DIP and FLAT packages.

The transceivers take a differential ECL level NRZ data signal from the available Fibre Channel silicon. This signal is converted to a drive level and pre-conditioned with an output filter and sent on the cable through an interfacing wideband pulse transformer. The transformer converts the signal to current and voltage levels suitable for transmission on STP cable with exceptionally low transmit jitter. The transceiver matches the impedance of both the ECL circuit and the cable plant, providing a resultant output signal with less jitter and return loss than any other device in the industry. The receiver portion of the transceiver takes the signal off the STP cable and equalizes the signal through a proprietary magnetic interfacing wideband pulse transformer and circuitry. This initiates the conversion process of reducing the compsite signal to an ECL level NRZ data signal for the mating Fibre Channel Silicon.
