S.I. Tech model 2139 is a mini multidrop optical Bit-Driver with three fiber ports providing total optical isolation for RS-232 data transmission up to 115 Kbps. It features upstream and downstream ST-connected fiber ports with 50/62.5 µm multimode or 10 µm single-mode operation, supporting distances up to 2,000 meters for multimode and 7,000 meters for single-mode fiber. The RS-232 port inserts and drops data exclusively on the upstream fiber line. Optical input power is 10 microwatts at 850 nm with a 13 dB power budget, and receiver sensitivity is 500 nanowatts at less than 10^-9 bit error rate. The device operates on +12 VDC, with an operating temperature range of 0°C to 50°C, housed in a metal enclosure measuring 4.80 x 2.25 x 1.0 inches, and supports panel or DIN rail mounting. It meets FCC Class A, Part 15 requirements for computing devices.
S.I. Tech model 2139 is a mini multidrop optical Bit-Driver that contains three fiber ports. The upstream and downstream fiber ports repeat data through the 2139 multidrop and drop/insert data on the RS-232 fiber port. The RS-232 fiber port inserts data onto upstream fiber port only and gets data dropped from upstream fiber port only. The downstream fiber port only sends/receives data from the upstream fiber port. Having fiber on all three ports provide total optical isolation to attached equipment.
