Description
The AFCT-5971LZ/ALZ are high performance, cost effective modules for serial optical data communications applications specified for a signal rate of 125 Mbd. They are designed for fast ethernet applications and are also compatible with the EFM baseline 100-BASE-LX10 standard over dual single mode fiber.
All modules are designed for single mode fiber and operate at a nominal wavelength of 1300 nm. They incorporate high performance, reliable, long wavelength optical devices and proven circuit technology to give long life and consistent service.
The transmitter section of the AFCT-5971LZ/ALZ incorporates a 1300 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 PIN photodetector for low dark current and excellent responsivity.
A pseudo-ECL compatible logic interface simplifies interface to external circuitry. These transceivers are supplied in the new industry standard 2 x 5 DIP style package with the LC fiber connector interface and is footprint compatible with SFF Multi Source Agreement (MSA).
