T-3 to fiber conversion - Racks, raceways and tools

Communications News, Sept, 2002

T-3-to-fiber and E-3-to-fiber interface models are capable of achieving extended distances of up to 2 km over multimode (1310 nm) and 100 km over single-mode fiber (1550 nm). The Radiance T3/E3 Interface is a high-speed integration and conversion of T-3 (44.736 Mbps) or E-3 (34.368 Mbps) serial copper TDM communication lines to fiber-optic links. Regardless of line codes or framing, the copper data stream is converted to optical signals for greater noise immunity and longer transmission. In order to ensure reliable transmission, the TDM interface, which converts the TDM data stream to fiber, supports a self-clocking code using a pulse-width modulation scheme that converts TDM clock information to a format suitable for fiber-optic communication.--Metrobility
