S.I. Tech, Inc. Opt. Asynch/Synch Mini Bit Driver® 3503

The Model 3503 is an optical asynchronous/synchronous mini bit-driver designed for full-duplex communication over fiber optic links, supporting synchronous speeds up to 9.6 Kbps and asynchronous speeds up to 19.2 Kbps with control signals. It features an SMA connector for fiber optic interface and an RS-232-C Type D interface for DTE connection. The device operates over distances up to 2000 meters (6600 ft) with 50, 62.5, or 100-micron core fibers, using 850 nm wavelength optics with 1 μW transmit power and 30 nW receiver sensitivity. It meets FCC Class A, Part 15 requirements and is housed in a metal enclosure measuring 4.25 × 10.2 × 2.2 cm, with an operating temperature range of -20°C to 85°C. External power is supplied via a 12 VDC adapter.
