The Model 2821 is a two-channel TTL to fiber optic receiver for high-speed data transmission up to 50 Mbps. It outputs TTL signals via BNC connectors and accepts 9-32 VDC input, with a maximum power draw of 1.5 W. Optical reception operates at 820 nm, with 1300 nm and 1550 nm options available, and has a minimum sensitivity of 3 µW (-25 dBm) for BER ≤ 10^-9. It uses ST optical connectors and supports transmission up to 2 km over multimode fiber or 10 km over single mode fiber. The enclosure measures 5.125 × 2.125 × 1.0 inches (13.00 × 5.40 × 2.54 cm) and weighs 6 oz (170 g). It operates from 0°C to 50°C and complies with FCC Class A, Part 15 standards.
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.
