Can this module be connected to multi-mode fiber in our older building network?

No. This 1G CWDM SFP module is designed for single-mode fiber, not multi-mode fiber. For multi-mode links, you would need a different 1G SFP model designed for the required fiber type and distance.

We need a small trial order before placing a large purchase order. Can we test a few units first?

Yes, a sample order is a practical way to validate switch recognition, DOM readings, optical budget, and MUX/DEMUX channel matching before a larger rollout. Please confirm the required compatibility coding for the sample modules.

Can DOM help us identify a dirty LC connector before the link goes down?

Yes. A gradual drop in received optical power shown through DOM may indicate connector contamination, fiber bending, aging patch cords, or increasing splice loss. It can help engineers investigate the link before it fails completely.

Our SAN uses 1.063Gbps Fibre Channel links between two storage switches. Can this 1390nm CWDM SFP be used for that application?

نعم فعلا. ال LINK-PP LS-CW391G-80C supports 1.063Gbps Fibre Channel and can be used for long-distance SAN connections over single-mode fiber. Please also confirm the required vendor coding for your Fibre Channel switch model.

This is a practical 1390nm CWDM 1G SFP module for legacy aggregation switches that still need long-distance optical links. TX/RX power levels looked healthy from day one, and the Duplex LC interface made replacement straightforward.

Commissioned 20 units of these 80km 1390nm CWDM transceivers for a wireless cell site backhaul aggregation project. The primary requirement was stable physical layer signal integrity across long optical paths without active amplification. The DFB laser stability on these optics is impressive — zero channel bleed-over to adjacent wavelengths (1370nm/1410nm) on our multiplexer. The duplex LC receptacles feature high-precision internal alignment sleeves, keeping insertion loss below 0.2dB per connection point. Operating in our climate-controlled indoor POP shelters, operating temperatures sit steadily around 36°C.

We used the LS-CW391G-80C CWDM SFP module to extend a 1GbE connection between two campus buildings over single-mode fiber. The 1390nm channel matched our CWDM MUX setup, and both ends linked without any tuning or special configuration.

Good choice when you need an 80km CWDM SFP rather than a standard 1310nm gray optic. The DFB CWDM laser provides a clean fit for our passive CWDM transport design, and the price is reasonable for project quantities.

Installed a batch in a managed network supporting remote access cabinets connected back to an indoor aggregation room. Although the optics are commercial temperature rated, the modules are located in climate-controlled equipment areas, and the long single-mode runs are entirely within the 80km design target. The DFB transmitter and PIN receiver combination gave stable receive levels over the route, and the 1.25Gbps throughput is exactly right for the existing access layer. We also appreciate that the modules conform to SFP MSA and support DOM, since our NOC can trend optical levels instead of waiting for a service incident. This is the kind of low-drama optic operations teams want.

Our operations team likes the DOM support because we can check temperature, voltage, laser bias, transmit power, and receive power remotely. It makes preventive maintenance much easier than using non-DOM optics.

For a data-center-to-campus extension project, we needed a proven 1390nm CWDM transceiver that would work over existing single-mode fiber and LC patching. The LS-CW391G-80C did exactly that. We installed it as a 1.25Gbps uplink, confirmed the correct 1390nm channel through the passive CWDM infrastructure, and monitored DOM values through our normal network-management workflow. No special configuration was needed beyond selecting the correct compatibility version during procurement. It is a good fit for enterprise backbone, metro Ethernet, and indoor telecom-room applications where a 1G CWDM 80km SFP is required.

Our team needed to reuse a limited pair of single-mode fibers between a central data room and several remote utility sites. We selected multiple CWDM wavelengths and used the 1390nm LS-CW391G-80C for one of the longer 1.25G services. The Duplex LC format integrated directly with our fiber distribution frame, while the SFF-8472 digital diagnostics were available through the switch CLI for normal monitoring. We checked laser TX power, RX power, temperature, and voltage during commissioning, then set alert thresholds based on the measured baseline. The modules have performed consistently and saved us from installing additional outside-plant fiber.

We used these SFP transceivers for a phased refresh of older 1G CWDM uplinks in a regional enterprise network. Before rollout, we tested samples across our standard equipment inventory, validated DOM visibility, and measured optical power after the CWDM MUX, patch cords, and field fiber were included. The 1390nm channel stayed within the expected budget, and the modules did not show unusual temperature or bias-current behavior during burn-in. In production, they have supported normal enterprise traffic without errors or unexpected resets.

We deployed 10 LS-CW391G-80C CWDM modules in a campus fiber consolidation project, using 1390nm as one channel in an existing CWDM MUX/DEMUX system. The longest route was just under 70km including patch-panel and splice loss. DOM readings were consistent across the batch, and the reported receive power gave us enough margin to document the links before handover. After several weeks of carrying office, security, and management traffic, interface counters remain clean with no recurring link events. For indoor 1GbE CWDM backbone work, this is a dependable SFP option.
