PTRX155ST-1

Inc

PD-LD Inc. offers singlemode
laser based fiber optic transceiver
modules in convenient industry
standard 1X9 style packages. The
PTRX series modules are designed to
comply with SONET/SDH standards for
155MBs operation over 9/125um
singlemode optical fiber.
The transmitter section is built
using 1310nm FP laser diodes and an
IC driver that converts PECL signals
into an optical output stream. The
driver circuit maintains operation of the
laser diode over an industrial operating
temperature range of –40 to 85°C. The
output of the laser diode is regulated
such that they meet the Class 1 Eye
Safety standards as outlined by the ITU
documents EN 60825-1.
The receiver section is built using
a high sensitivity InGaAs PIN
photodiode that converts incoming
optical light into a current output. This
ouput is then fed to a transimpedance
amplifier and post amplifier which
produces PECL data. The pre-amp
circuit contains an automatic gain
control ( AGC) feature that permits
operation with high optical input power
(0dBM) without saturating.
These modules are designed for
operation with a single +5V power
supply.
