MTNetworks SFP 2.5G LR SDH/STM-16 SONET/OC-48 Tx1550nm/Rx1310nm 10km

The MTNetworks MT-SFP-OC48-LRA/B is a high-performance 2.5G BiDi SFP optical transceiver designed for SONET OC-48, SDH STM-16, Fibre Channel, enterprise backbone, and metro optical networks. Supporting data rates up to 2.5 Gbps, the module enables reliable 10 km optical transmission over Single-Mode Fiber (SMF) using single-fiber BiDi technology, reducing fiber requirements while maintaining carrier-grade performance.

The module is available as a complementary BiDi pair:

  • MT-SFP-OC48-LRA: 1310 nm Transmitter / 1550 nm Receiver
  • MT-SFP-OC48-LRB: 1550 nm Transmitter / 1310 nm Receiver

The transceiver integrates a DFB laser transmitter, high-sensitivity PIN photodiode receiver with TIA, built-in Digital Diagnostic Monitoring (DDM), and a hot-pluggable SFP form factor with a simplex LC optical connector. It is optimized for carrier and enterprise optical transmission over a single fiber.
