Avago Technologies AFBR 5803TZ Fiber Optic Transceiver

The Avago Technologies AFBR-5803TZ is a 100 Mb/s fiber-optic transceiver in a compact 1×9 package with an ST duplex optical interface. It combines a 1300 nm transmitter and a receiver in a single through-hole module, supporting duplex links for Fast Ethernet 100BASE‑FX, 100 Mb/s ATM, and related backbone applications over multimode fiber. The transceiver is specified for operation from a 3.3 V or 5 V supply and uses a through-hole ST connector for fiber termination, making it suitable for integration into legacy network equipment and backplane or multi-device fiber links that require a dedicated TX/RX transceiver in a single module. With its nominal 1300 nm wavelength, the AFBR-5803TZ aligns with common 1300 nm MMF systems, delivering a simple, low-profile solution where 100 Mbps fiber connectivity is needed in a compact form factor.
