MTNetworks SFP 155M ER SDH/STM-1 SONET/OC-3 1550nm 40km

The MTNetworks MT-SFP-OC3-ER is a 155Mbps SFP optical transceiver designed for long-distance optical communication over single-mode fiber (SMF). Utilizing a 1550 nm DFB laser transmitter and a PIN photodiode receiver, the module supports transmission distances of up to 40 km, making it suitable for SONET OC-3, STM-1, Fast Ethernet, and other 155Mbps optical networking applications requiring reliable extended-reach optical connectivity.

Designed in a hot-pluggable SFP form factor, the module features a duplex LC optical interface, integrated Digital Diagnostic Monitoring (DDM) compliant with SFF-8472, and full interoperability with the SFP Multi-Source Agreement (MSA). Real-time monitoring of temperature, supply voltage, laser bias current, transmit optical power, and receive optical power enables simplified network management, making the transceiver suitable for carrier transport networks, enterprise optical infrastructure, utility communications, and industrial fiber applications.
