We need to connect two campus nodes over an existing single-mode fiber span. What is the maximum transmission distance supported by this optical module?

The transceiver utilizes a CWDM DFB laser transmitter paired with a high-sensitivity PIN photo detector, enabling optical link spans of up to 80km over standard single-mode fiber terminated with duplex LC connectors.

We require continuous telemetry for predictive maintenance in our NMS. Does this transceiver support hardware monitoring without interrupting live traffic?

Yes. It features an integrated real-time digital diagnostic monitoring function compliant with SFF-8472, allowing your host system to monitor operational metrics such as internal temperature, supply voltage, laser bias current, TX optical power, and RX optical power in real time.

We want to multiplex both Gigabit Ethernet traffic and SAN traffic over our CWDM network. Can this 1350nm SFP module transport 1.063Gbps Fiber Channel?

Yes. The LS-CW351G-80C module supports bit rates up to 1.25Gbps. It is fully qualified for both 1.063Gbps Fiber Channel and Gigabit Ethernet applications across CWDM optical links.

We are building an 8-channel CWDM metro ring and need to purchase a batch of the 1350nm CWDM 1G SFP modules. Do you offer bulk tiered pricing for project rollouts?

Yes, we offer tiered volume pricing for bulk orders of the LS-CW351G-80C module. Please let us know your required quantity, target delivery timeline, or any other CWDM wavelengths you might need. Feel free to contact our team directly, and we will be glad to provide a detailed quote and availability for you.

Some of our distribution cabinets experience temperature fluctuations during peak summer loads. Does the module include temperature alert capabilities, and what are its environmental compliances?

Yes. Real-time operating temperature is continuously tracked via the built-in DDM function to alert when the threshold is exceeded. Furthermore, the unit is fully compliant with RoHS environmental directives and operates from a standard single +3.3V power supply.

In a multi-tenant office park, we used this 80km CWDM module to connect our core to a remote distribution building over existing SMF, running alongside other CWDM channels on a shared MUX/DEMUX. The 1350nm channel integrated cleanly with no crosstalk issues, and the duplex LC connectors made patching straightforward during our weekend changeover.

We use these CWDM SFP modules to expand channel capacity on our dark fiber lease without pulling new cables. The 1350nm wavelength grid alignment is precise, keeping adjacent channel crosstalk non-existent.

Rebuilt our off-site backup storage path using these 80km transceivers over standard G.652 single-mode fiber. The optical power budget is generous enough that we didn't need inline optical amplifiers to keep latency and jitter minimal.

Our campus fiber upgrade replaced legacy 1310nm optics with this 1350nm CWDM SFP to free up spectrum for future growth, and the transition was seamless across our mixed-vendor switch environment. The DOM support gave us real-time visibility into link health, and the 80km reach gave us plenty of margin for our longest spans without needing extra amplification.
