Key Features of Extreme CWDM-SFP-1290 Compatible LINK-PP 1.25G SFP
Extreme CWDM-SFP-1290 Compatible LINK-PP module is a commercial-grade 1290nm CWDM SFP module that delivers 1Gbps data rates over single-mode fiber up to 80km. It incorporates a duplex LC optical interface, real-time digital optical monitoring (DOM), and full compliance with the SFP MSA standard. The hot-pluggable form factor enables easy installation and field replacement without system interruption.
This optical module adopts the standard hot-pluggable SFP footprint, allowing direct insertion into any SFP-compliant port. Its electrical and mechanical interfaces are fully aligned with the SFP MSA, ensuring interoperability with a wide range of host equipment.
CWDM-SFP-1290: 1 Gbps Connectivity for Regional Long-Haul Links
Designed for regional long-haul backbones, this transceiver provides a 1Gbps throughput over extended network spans. Its stable data rate ensures that traffic flows smoothly across point-to-point trunks, with minimal variation in latency under normal operating conditions.
CWDM-SFP-1290 Module with CWDM Technology for Fiber Efficiency
The CWDM approach multiplexes multiple wavelength channels onto a single fiber, significantly reducing the need for additional fiber strands. This technology maximizes existing infrastructure capacity, lowering both deployment costs and cable plant complexity.
CWDM-SFP-1290 Module with 1290nm Wavelength
The 1290nm wavelength sits within the CWDM spectrum and delivers a good combination of relatively low dispersion and manageable loss over single-mode fiber. Its adoption leverages the inherent optical properties of this band, supporting clean eye patterns and stable power budgets for the link.
CWDM-SFP-1290 Module Supporting 80km Transmission
The transmission distance reaches up to 80km over single-mode fiber without requiring external amplification or dispersion compensation. This reach is achieved through the DFB laser’s optical output power and the PIN receiver’s sensitivity, ensuring reliable link closure at the specified bit rate.
CWDM-SFP-1290 Module with Duplex LC Interface
The duplex LC connector provides a compact, snap-in locking mechanism that ensures secure fiber mating and low insertion loss. This industry-standard interface facilitates quick patching and is compatible with most optical distribution frames and patch panels.
CWDM-SFP-1290 Module with DOM for Real-Time Monitoring
The DOM (Digital Optical Monitoring) function continuously tracks key operating parameters, including transmitter bias current, receiver optical power, supply voltage, and internal temperature. These real-time readings allow network administrators to proactively detect link degradation and troubleshoot faults remotely via the host management bus.

We deployed these modules in a metro CWDM ring for a municipal network, connecting offices and facilities over existing single-mode fiber. The 1290nm channel slots neatly into our wavelength plan, and the links have been stable through daily traffic peaks. DOM data helps our operations team prioritize maintenance, especially on longer spans where margin is tighter. Installation was quick, with no special commands needed on the switches we use. For a city-wide 1G backbone, this transceiver delivers the reliability and visibility we require.

Excellent 80km CWDM SFP module with clean DOM data; the only hiccup was that the customs paperwork had a minor typo in the description. It didn’t affect the product, but it did delay clearance by a day. Everything else was perfect.

We used a pair of these LS-CW291G-80C 1G CWDM optical transceivers to connect two 1G switches over a dedicated SMF path for a critical NAS and backup network. The duplex LC interface made cabling clean and predictable, and DOM let us validate the entire link budget end-to-end. Under continuous file transfers and virtualization traffic, the connection stayed stable with no drops or retransmissions. It’s reassuring to have optical monitoring built in, so we can spot degradation before it becomes an outage. For a small but important fiber segment, this module hits the right balance of performance and price.

We rolled these 1G CWDM 1290nm SFP transceiver modules into a multi-site campus ring, and the links have been rock solid under real production load. DOM telemetry gives our NOC clear visibility without extra probes, and the 80km class rating covers all our current and planned hops. Deployment was straightforward with standard duplex LC patching on SMF, and we haven’t seen any flapping or error spikes. The commercial temperature range fits our climate-controlled rooms perfectly. For a cost-effective CWDM transceiver, the stability and monitoring capabilities are exactly what we needed.
