Product Detail

1.25G DWDM SFP 160KM LC Optical Transceiver is an ultra-long-haul, high-performance optical module engineered for extreme-distance communication in Dense Wavelength Division Multiplexing (DWDM) systems. Operating on precise ITU-T grid wavelengths with narrow channel spacing, it enables the transmission of multiple high-speed data streams over a single fiber strand, maximizing bandwidth capacity while optimizing fiber infrastructure utilization.

Supporting data rates of 1.25Gbps, this transceiver achieves an exceptional transmission distance of up to 160 kilometers over standard single-mode fiber, making it ideally suited for inter-city networks, cross-regional backbone links, and nationwide telecommunications infrastructure requiring maximum channel density and ultra-long reach.

Featuring enhanced transmitter power and superior receiver sensitivity with integrated dispersion tolerance, the module maintains excellent signal integrity across extended distances while operating reliably under varying environmental conditions.

The hot-pluggable SFP form factor with duplex LC interface ensures seamless integration with existing network equipment, providing carriers and enterprises with a scalable, future-proof solution for building robust, high-capacity optical transport networks with minimized operational costs.
