SFP-1FELLC-T-BCC | Moxa Compatible 100MB Single-Mode 80km (100BASE-ZX)

Q: Will this work in place of the Moxa SFP-1FELLC-T?
A: Yes. This transceiver is a drop-in replacement for the SFP-1FELLC-T, matching the same SFP form factor, 100 Mbps data rate, 1550nm wavelength, and 80km single-mode reach. It is IEEE 802.3u compliant and provides plug-and-play compatibility with Moxa switches and routers that specify the SFP-1FELLC-T.

Q: Which Moxa platforms support this transceiver?
A: This module is compatible with Moxa Ethernet switches that feature SFP slots supporting 100BASE Fast Ethernet, including the SFP-1FE series-compatible platforms. The transceiver works in any Moxa switch or router port that accepts SFP modules and supports 100 Mbps operation per the platform datasheet.

Q: What single-mode fibre type is required for 80km reach?
A: This transceiver requires 9/125um single-mode fibre (SMF), typically OS1 or OS2 grade. Actual reach depends on the fibre quality, number of splices, connector loss, and total link budget. The 1550nm wavelength provides lower attenuation than 1310nm, enabling the extended 80km distance over clean single-mode fibre spans.

Q: Can I access DOM parameters on this transceiver?
A: Yes. The transceiver supports digital diagnostic monitoring per SFF-8472, providing real-time access to transmit power, receive power, temperature, supply voltage, and laser bias current. Most Moxa managed switches expose these parameters via CLI or web interface, enabling proactive link health monitoring and troubleshooting.

Q: Is an optical attenuator required for short single-mode spans?
A: For spans shorter than approximately 8 to 10km, an inline optical attenuator may be required to prevent receiver overload. The high output power needed for 80km reach can saturate the receiver on very short links. Consult the link budget calculation and receiver saturation threshold to determine if attenuation is necessary for your specific span length.
