050-331 Product Brief

PC Board Mount Dual-Transmitter

3G-SDI and HD-SDI, MMF, 3.3V

PC Board Mount Fiber Optic Dual-Transmitter, 3G-SDI & HD-SDI, MMF, 3.3V

Glenair 050-331, is a ruggedized harsh environment PC Board Mount Dual-transmitter

with electrical and optical functionality similar to transmitters in 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 board mount optical dual-transmitters also support Digital

Monitoring Interface (DMI) features in accordance with SFF 8472. The dual-transmitter

interfaces with a host board through a high speed electrical connector.

Each transmitter includes a Transmitter Optical Subassembly (TOSA) and laser driver

circuitry. The TOSA, containing an 850 nm VCSEL (Vertical Cavity Surface Emitting

Laser) light source, is located at the optical interface and mates with the GC optical

connector. The TOSA is driven by a laser driver, which converts differential logic

signals into an analog laser diode drive current. This laser driver circuit regulates the

optical power at a constant level provided the data pattern is relatively DC balanced

and can support SMPTE EG 34:2004 Pathological conditions CASE 1, CASE2, and

CASE 3 for HD-SDI and 3G-SDI
