HS-SFP-GE-BX20-SC

Q: Why would I pick the SC version of the BiDi module?

Connector fit: if your patch panels, splice trays and field terminations are all SC, the HS-SFP-GE-BX20-SC plugs straight in without LC-to-SC patch cords. Optically it is the same single-fiber BiDi design — full-duplex 1.25 Gb/s over one single-mode strand for 20 km using 1310/1550 nm coarse WDM.

Q: How do A/B pairing and distances work here?

Identical to the LC BiDi family: model A transmits at 1310 nm and receives at 1550 nm, model B is the mirror, and every link needs one of each at opposite ends. The 20 km grade is standard, with TX power from -8 to -3 dBm and receiver sensitivity of -24 dBm on 9/125 µm fiber.

Q: Is it manageable and brand-compatible?

DDM digital diagnostics per SFF-8472 report TX power, RX power and temperature to the host device, so link health is visible from your management system. It works in our converters and switches, and in major-brand SFP slots with compatibility coding on request. Certification is RoHS with IEC 60825 laser class 1; industrial temperature grade optional.
