This is a bi-directional small form factor transceiver designed for full-duplex communication over a single fiber. The single fiber concept saves overall system costs by eliminating one fiber, allowing for doubling of capacity without installing new fibers, and simplifying fiber management.
The Infineon BIDI‑TRX is a bi‑directional Small Form Factor (SFF) transceiver that combines a 1310 nm transmitter and a 1550 nm receiver in a single unit, using a single‑mode fiber pigtail. It operates at 155 Mbit/s, requires a 3.3 V supply, and offers PECL/LVPECL compatible differential I/O. The device includes an integrated WDM filter, laser driver, and automatic shutdown for eye‑safety.
Typical applications include access networks (FITL, P2P, PON), inter‑system links in data centers, and CCTV video transport. Ordering options cover various connector types (SC/PC, SC/APC, MU, LC, etc.). The datasheet provides detailed pin assignments, electro‑optical characteristics, and mechanical dimensions for PCB integration.
