HFCT-5903E
MT-RJ Duplex Single Mode Transceiver
Data Sheet
Description
The HFCT-5903E transceiver is a high performance, cost
effective module for serial optical data communications
applications specified for a signal rate of 125 MBd. It is
designed to provide an FDDI SMF-PMD1 link for FDDI or
Fast Ethernet applications and is also compatible with
ATM/SONET/SDH transceivers. The HFCT-5903 does not
include a nose shield and is not recommended due to the
potential degradation of EMI performance in a complete
system. The HFCT-5903 is available on the rare occasion
that a system mechanical design may not allow for a
nose shield.
This module is designed for single mode fiber and
operates at a nominal wavelength of 1300 nm. It incor-
porates Avago’s high performance, reliable, long wave-
length optical devices and proven circuit technology to
give long life and consistent service.
The transmitter section uses an advanced SMQW Fabry
Perot laser with full IEC 825 and CDRH Class I eye safety.
The receiver section uses a MOVPE grown planar PIN
photodetector for low dark current and excellent re-
sponsivity.
A pseudo-ECL logic interface simplifies interface to
external circuitry.
