HFCT-5903E

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. HFCT-5903E is designed to provide an FDDI SMF-PMD1 link for FDDI or Fast Ethernet applications and is also compatible with ATM/ SONET/SDH transceivers. HFCT-5903E does not include a nose shield and is not recommended due to the potential degradation of EMI performance in a complete system. HFCT-5903E is available on the rare occasion that a system mechanical design may not allow for a nose shield.

This HFCT-5903E module is designed for single mode fiber and operates at a nominal wavelength of 1300 nm. It incorporates Agilent's high performance, reliable, long wavelength 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 responsivity. A pseudo-ECL logic interface simplifies interface to external circuitry.
