The Model 2228 is an optical mini bit-driver that converts RS-485 signals to fiber optic links, supporting asynchronous half- or full-duplex operation up to 256 Kbps. It features ST connectors for multimode fiber as standard, with single-mode as an option, and transmits with 10 microwatts of optical power into 62.5-micron core fiber. The receiver sensitivity is 500 nanowatts at a bit error rate below 10^-9, supporting distances up to 2000 meters with multimode fiber and 10,000 meters with single-mode fiber. Operating temperature ranges from -40°C to +85°C, with a metal enclosure measuring 4.80 x 2.25 x 1.0 inches. It supports panel or DIN rail mounting and complies with FCC Class A, Part 15 requirements. Input power is provided externally via a 12 VDC supply.
Fiber ports repeat data through the 2228 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.
