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.

In a private enterprise network, we used these SFPs to extend 1G connectivity between buildings using a simple CWDM mux/demux pair. The optical performance has been consistent across all deployed units, with clean link establishment and no unexpected resets. Having DOM available on every port simplifies troubleshooting and reduces the need for external test gear during changes. The 80km class rating means we can reuse the same stock for both short and medium-distance links without worrying about spec mismatches.

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.

In a small ISP backhaul use case, these modules sit behind a passive CWDM mux and handle long-haul SMF runs with plenty of margin. The optical performance feels consistent across the batch, with clean handshakes and stable link states on all ports. We rely on DOM for proactive maintenance, and the readings line up well with our link budget expectations. No special configuration was required on the switches we tested, which sped up the rollout.

No issues with optical performance or DOM readings; the only downside was that the shipping took two days longer than the estimated window. The module was securely packed and deployed without problems. Would still recommend, but logistics could be tighter.

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.
