050-321 Product Brief

PCB Mount Transceiver

10 Mbps – 200 Mbps, MMF, 3.3V

PCB Mount Fiber Optic Transceiver, 20Mbps-200Mbps, MMF, 3.3V

Glenair 050-321, is a ruggedized harsh environment PCB Mount Transceiver

with electrical and optical functionality equivalent to SFP transceivers but with

mechanical design that is suited to the harsh temperature and vibration environments

found in Military, Aerospace, Railway, Oil and Gas, and Industrial applications. The

PCB mount optical transceivers also support optional Digital Monitoring Interface (DMI)

features in accordance with SFF 8472. The Transceiver is comprised of a transmitter

section and a receiver section that resides on a common package and interface with a

host board through a high speed electrical connector.

The transmitter section includes the Transmitter Optical Subassembly (TOSA)

and LED driver circuitry. The TOSA, containing a 1300nm LED light source, is located

at the optical interface and mates with the GC optical connector. The TOSA is driven

by a LED driver, which converts differential logic signals into an analog drive current.

The receiver section includes the Receiver Optical Subassembly (ROSA) and

amplification/quantization circuitry. The ROSA, containing a PIN photodiode and trans-

impedance preamplifier, is located at the optical interface and mates with the GC

optical connector. The ROSA is mated to a limiting amplifier IC that provides post-

amplification and quantization. Also included is a Loss Of Signal (LOS) detection

circuit.
