Optical and electrical drivers
Introduction
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:
-
Optical
-
LL: long wave laser (1300 nm)
-
SL: short wave laser (780 nm)
-
LE: LED (1300 nm)
-
Electrical
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.
Devices
Optical drivers and receivers exist from the following manufacturers:

Maxim
The MAX3260/MAX3261/MAX3262, from Maxim Integrated Products is a complete
fibre optic transceiver chipset for 1063 Mbps Fibre Channel applications.
The chipset includes a preamplifier, post amplifier and laser driver.
The MAX3260 is a high-speed transimpedance amplifier. Its extended dynamic
range makes it useful in optical receiver systems with as much as 25 dB
of input signal range. It operates from a single +5V supply.
The MAX3261 is a 1.2 Gbps laser diode driver that has complementary
enable inputs that allow it to interface with open-fibre-control architecture.
It includes a TTL-compatible laser failure indicator and a programmable
slow-start circuit to prevent laser damage.
With its high gain and wide bandwidth, the MAX3262 limiting amplifier
with chatter-free loss-of-signal detection is ideal for use as a post amplifier
in fiber free receivers with data rates up to 1 Gbps.

Technitrol
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.
