LS-CW331G-80C functions as a 1330nm CWDM SFP transceiver, rated for 1.25Gbps and 80km SMF transmission, with a DFB laser source and a PIN detector. Over the 0 - 70°C ambient range, it provides built-in real-time DDM functions that monitor critical operating parameters (like optical power, bias current, temperature, and voltage) without external metering. The module’s wavelength stability and dispersion tolerance are specifically defined for long-haul CWDM links at this reach.

LINK-PP LS-CW331G-80C is a hot-pluggable SFP transceiver that complies with SFP MSA and delivers 1Gbps over 80km of single-mode fiber using a 1330nm CWDM channel. It features a duplex LC connector and built-in DDM for real-time optical monitoring, while its 0-70°C operating range ensures stable operation in typical commercial environments.
This SFP-compliant module adopts a hot-pluggable footprint that fits standard SFP ports. It fully meets MSA requirements for mechanical, electrical, and management interfaces, enabling straightforward integration into existing network systems.
Supporting 1Gbps bit rates, this transceiver is well suited for point-to-point backhaul applications. It delivers consistent gigabit throughput over dedicated fiber paths between two network nodes.
Built with CWDM multiplexing, this optic allows multiple wavelength channels to share a single fiber strand. By operating on a designated 1330nm channel, it helps operators expand capacity without laying additional cables.
The 1330nm wavelength offers a favorable balance between attenuation and dispersion in standard single-mode fiber. This choice minimizes signal distortion and ensures stable transmission performance across the rated distance.
Rated for 80km transmission, the module provides sufficient optical budget for long-haul single-mode fiber runs. Its DFB laser and PIN receiver are tuned to preserve signal integrity even at the maximum reach.
Equipped with a duplex LC connector, this interface ensures secure, polarity-correct fiber connections. The LC form factor is widely adopted, which simplifies cabling and patch-panel integration.
Including digital diagnostic monitoring (DDM), the transceiver gives real-time visibility into Tx/Rx power, laser bias current, operating temperature, and supply voltage. This data enables network administrators to quickly detect fiber degradation or link anomalies.
