Product Overview
The SFM-5002-WB is a 155Mbps (Fast Ethernet/OC3) BiDirectional Small Form-Factor Pluggable (SFP) optical transceiver manufactured by CTC Union. Designed for single-strand multimode fiber transmission, this module utilizes wavelength-division multiplexing (WDM) to transmit at 1550nm and receive at 1310nm. It enables the consolidation of duplex fiber links into a single strand, maximizing existing fiber infrastructure. The module is fully compliant with 100Base-FX BiDi and OC3/155M BiDi standards and includes built-in Digital Diagnostic Monitoring (DDM).
For proper operation, the SFM-5002-WB must be paired with its complementary counterpart, the SFM-5002-WA (Tx:1310nm/Rx:1550nm). It is compatible with active equipment supporting SFP interfaces and is specifically validated for CTC Union FRM220 series converters with slow-speed interfaces, including the FRM220-SERIAL-SFP, FRM220-FXO-FXS-SFP, FRM220-CCF20, and FRM220-E1-T1-SFP.

Frequently Asked Questions
Which transceiver pairs with the SFM-5002-WB?
To establish a complete communication link, the SFM-5002-WB (Tx:1550nm/Rx:1310nm) must be paired with the complementary SFM-5002-WA transceiver (Tx:1310nm/Rx:1550nm) at the opposite end of the fiber.
Can this BiDi transceiver operate on standard duplex multimode fiber?
Yes, by utilizing wavelength-division multiplexing, this transceiver requires only a single strand of 50/125µm or 62.5/125µm multimode fiber. This allows a standard two-strand duplex multimode circuit to support two independent full-duplex connections, or provides immediate redundancy if one strand becomes compromised.
What equipment is compatible with the SFM-5002-WB?
It is compatible with standard MSA-compliant SFP slots in Ethernet switches, routers, and gateways, and is explicitly verified for use in CTC Union FRM220 series converters (e.g., FRM220-SERIAL-SFP, FRM220-E1-T1-SFP) and FMC Dual-Speed converters.
