The 2820 is a high-speed 2-channel TTL to fiber optic transmitter for converting electrical signals to optical signals over multimode or single-mode fiber. It features two TTL input channels with BNC connectors, supporting data rates from DC to 50 Mbps and input power of 9-32VDC or optionally 5VDC. Optical output is 30 microwatts (-15 dBm) at 850 nm or 1300 nm via ST connectors. Transmission reaches up to 2 km over multimode fiber or 10 km over single-mode fiber, with a typical bit error rate better than 10^-9. The unit measures 5.125 x 2.125 x 1.0 inches (13.00 x 5.40 x 2.54 cm), weighs 6 oz (170 g), and operates from 0°C to 50°C. It meets FCC Class A, Part 15 standards for computing devices.
Operating distance is dependent upon optical fiber core diameter and the cable's optical attenuation. The table below indicates three cables that may be used at any data rate. These cables are available in connectorized assemblies to meet the exact configuration of your application.
S.I.Tech offers complete links including fiber optic cable, connectors, cable assemblies, and Bit-Drivers.
