The Model 2128 is an optical mini multidrop bit-driver that interfaces between RS-485 and fiber optic links, supporting asynchronous half-duplex communication up to 200 Kbps. It features flange mounting with a metal enclosure measuring 5.5 x 2.3 x 1.0 inches (13.97 x 5.84 x 2.54 cm) and weighs 0.4 lbs (182 grams). The unit uses ST connectors for multimode or single-mode fiber and operates with an external 12 VDC power supply. It supports transmission distances up to 2,000 meters over 62.5 micron multimode fiber and up to 10,000 meters over single-mode fiber, with a 13 dB optical power budget and receiver sensitivity of 500 nanowatts at less than 10⁻⁹ bit error rate. Operating temperature ranges from 0°C to 50°C, with extended options available. The device meets FCC Class A, Part 15 requirements.
Fiber ports repeat data through the 2128 and drop/insert data on the RS-485 port. The RS-485 port inserts data onto both fiber ports and gets data dropped from either fiber port.
