Description
The HFCT-5914ATLZ transceiver is a high performance,
cost effective module for serial optical data communica-
tions applications operating at 1.25 Gb/s. This module
is designed for single mode fiber and operates at a
nominal wavelength of 1310 nm. It incorporates high
performance, reliable, long wavelength optical devices
and proven circuit technology to give long life and con-
sistent service.
The transmitter section incorporates a 1310 nm Fabry
Perot (FP) laser. The transmitter has full IEC 825 and
CDRH Class 1 eye safety.
The receiver section uses an MOVPE grown planar
SEDET PIN photo detector for low dark current and ex-
cellent responsivity.
The transceiver is supplied in the industry standard 2 x
10 DIP style package with the LC fiber connector inter-
face and is footprint compatible with SFF Multi Source
Agreement (MSA).
