MTNetworks SFP 1.25G ZR 1550nm 140km

The MTNetworks MT-SFP-ZR-140 is a high-performance 1.25Gbps SFP optical transceiver designed for Gigabit Ethernet, 1G Fibre Channel, optical transmission systems, and long-haul backbone networks. Supporting data rates up to 1.25 Gbps, the module provides reliable optical transmission over Single-Mode Fiber (SMF) up to 140 km using a 1550 nm DFB laser transmitter and a Super TIA + APD receiver.

The module integrates a 1550 nm DFB laser transmitter, high-sensitivity APD photodiode receiver with Super TIA, built-in Digital Diagnostic Monitoring (DDM), and a hot-pluggable SFP form factor. Designed for carrier-grade optical infrastructure, it delivers excellent optical budget, low power consumption, and reliable long-distance optical transmission.
