V23870-Ax131-xx00
V23870-Ax132-xx00
This BIDI®-TRX is a bi-directional Small Form Factor
(SFF) transceiver designed for full-duplex
communication over a single fiber. The single fiber
concept saves overall system costs by eliminating
one fiber, allowing for doubling of capacity without
installing new fibers, and simplifying fiber
management.

Description
Description
The Infineon BIDI® transceiver - part of Infineon’s Small Form Factor transceiver family is based on the Physical Medium Depend (PMD) sublayer and baseband medium.
Infineon's BIDI-TRX is designed to handle multiple data rates and can be designed into
Fast Ethernet, FDDI, Fiber Channel, ATM-155, SDH STM-1, SONET OC-3, CCTV and
other applications as well as different FTTx applications according to the 100 Mbps EFM
standard (IEEE 802.3ah). It is suitable for both, short haul applications and distances of
20 km and beyond.
The appropriate fiber optic cable is the 9µm singlemode fiber pigtail with different
connector options.
The Infineon BIDI transceiver is a single unit comprised of a transmitter, a receiver, WDM
filter, and a singlemode fiber pigtail. This design frees the customer from many alignment
and PC board layout concerns.
This transceiver operates at 155 Mbit/s from a single power supply (+3.3 V). The full
differential data inputs and outputs are PECL and LVPECL compatible.
Functional Description of 2x5 Pin Row Transceiver
This transceiver is designed to transmit and receive serial data via a single mode cable.

Description
The receiver component converts the optical serial data into PECL compatible electrical
data (RD+ and RD-). The Signal Detect (SD, active high) shows whether an optical
signal is present.
The transmitter converts PECL compatible electrical serial data (TD+ and TD-) into
optical serial data. Data lines are differentially 100 Ohm terminated.
The transmitter contains a laser driver circuit that drives the modulation and bias current
of the laser diode. The currents are controlled by a power control circuit to guarantee
constant output power of the laser over temperature and aging.
The power control uses the output of the monitor PIN diode (mechanically built into the
laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the
operating limits.
Single fault condition is ensured by means of an integrated automatic shutdown circuit
that disables the laser when it detects laser fault to guarantee the laser Eye Safety.
The transceiver contains a supervisory circuit to control the power supply. This circuit
makes an internal reset signal whenever the supply voltage drops below the reset
threshold. It keeps the reset signal active for at least 140 milliseconds after the voltage
has risen above the reset threshold. During this time the laser is inactive.
The laser can be disabled by the TxDis input.

An increase in optical power above the specified level will cause the Signal Detect output to switch from a low
state to a high state.
A decrease in optical power below the specified level will cause the Signal Detect to change from a high state
to a low state.
