SFP transceiver for OC-3 links

The Finisar FTLF1323P1BTR is a hot-pluggable SFP transceiver built for OC-3 IR-1 and STM S-1.1 networks. It delivers a 155 Mbit/s data rate over single-mode optical fiber using an LC duplex connector. The module suits data-centre and carrier optical networks that require standards-based SONET and SDH compatibility.

Sustained load behaviour

Digital diagnostics run continuously over the 2-wire serial bus defined in the SFP MSA, letting operators monitor optical power and temperature during long-haul operation. RoHS-compliant, lead-free construction meets Directive 2002/95/EC and Finisar Application Note AN-2038, supporting reliable service in environmentally regulated deployments.

Pre-order checklist

Verify that your host equipment accepts MSA-compliant SFP modules and provides an LC duplex port for single-mode fiber. Confirm the link budget matches the IR-1 reach requirement for your span. Ensure the management platform can read the 2-wire diagnostic interface for ongoing health checks.

Questions about this item

How much power does the FTLF1323P1BTR draw during continuous 155 Mbit/s operation?

The module is SFP MSA compliant and hot-pluggable, so power consumption stays within the standard SFP envelope for OC-3 IR-1 transceivers.

What host equipment is required to use this OC-3 IR-1 SFP transceiver?

A network device with an SFP cage that accepts hot-pluggable modules and supports OC-3/STM-1 over LC duplex single-mode fibre.

Will this Finisar SFP work alongside legacy OC-3 gear that uses SC connectors?

The transceiver terminates in LC duplex; a hybrid LC-to-SC patch cord links it to older SC-based OC-3 equipment without protocol changes.
