Description

This Farsince 25G SFP28 BiDi optical transceiver delivers bidirectional 25‑Gigabit Ethernet over a single strand of G.652 single‑mode fiber. The module transmits at 1330 nm and receives at 1270 nm through a simplex LC/UPC interface in a hot‑pluggable SFP28 housing. A DFB BiDi laser and PIN‑TIA receiver provide stable performance up to 10 km with digital diagnostics for real‑time monitoring. It is deployed in fiber‑constrained environments such as campus and enterprise aggregation, data center interconnects, and CPRI/eCPRI fronthaul where single‑fiber runs simplify routing and reduce fiber use.

Designed for straightforward integration, the transceiver follows the SFP28 MSA electrical interface and supports 25G Ethernet as well as CPRI/eCPRI. Using a matched pair (A: 1330Tx/1270Rx with B: 1270Tx/1330Rx) ensures proper WDM operation. Hot‑swap installation and standard LC connectivity minimize service windows. Farsince offers platform‑specific coding, project labeling and acceptance testing to align with OEM switches, routers and radio equipment while maintaining a reliable supply chain for large‑scale rollout.
