Our fiber route is about 72 km and includes patch panels and splice points. Can we use this 80km CWDM SFP module for the link?

Potentially, yes. The 80km rating is the maximum nominal transmission distance, but the total fiber loss must remain within the module’s optical budget after including fiber attenuation, connector loss, splice loss, and CWDM MUX/DEMUX insertion loss.

We already have a 1470nm CWDM module at the remote end. Can we pair it with this LS-CW451G-80C 1450nm module?

No. For a normal duplex CWDM connection, both ends should use matching 1450nm modules. A 1450nm module should not be directly paired with a 1470nm module.

Our modules are installed inside a controlled central office, but some racks run warm during peak traffic. Is the 0°C to +70°C rating based on ambient temperature or module case temperature?

The stated 0°C to +70°C specification is the operating case-temperature range. Actual module case temperature can be higher than room ambient temperature, depending on airflow, switch design, port density, and power consumption.

Our switch provides a standard 3.3V SFP power supply. Does this module need any additional power connection?

No. The LS-CW451G-80C module operates from a single +3.3V power supply through the SFP host interface and does not require an external power connection.

Good fit for a long-distance enterprise network where we still have active 1GbE access switches. The 1G SFP format saved us from replacing working equipment while adding another CWDM wavelength to the existing SMF pair.

We needed 1450nm CWDM modules specifically, not a generic 1310nm long-reach SFP. This module matched our CWDM channel plan, delivered a stable 1.25G connection, and fit our duplex LC patching setup perfectly.

Installed as part of a multi-vendor switch refresh where legacy access equipment still relies on standard SFP ports. We provided the required host coding information before ordering, and the modules were delivered ready for our planned device profile. On a 57km single-mode fiber link, the 1.25Gbps port negotiated normally and stayed stable through traffic tests. The Duplex LC interface was convenient because the field plant already used LC patch panels, and DOM helped quickly identify one dirty connector during installation.

A practical option for a 1G backbone over single-mode fiber. Our techs like that it is a standard duplex LC SFP, so there is no special handling beyond checking polarity and cleaning the connectors.

The module works well for long-haul 1G Ethernet transport where a 1450nm CWDM channel is needed. Vendor coding was handled before shipment, which made the rollout much faster for our operations team.

Ordered these 1G SFP modules for a CWDM MUX/DEMUX upgrade where the 1450nm channel was already assigned in the fiber plan. The modules came up quickly, and DDM monitoring lets our NOC keep an eye on transmit power, receive power, temperature, and supply voltage.

Our data-center team used this 1G 1450nm CWDM SFP module to carry management and storage-related traffic between facilities over single-mode fiber. It is not intended to turn a 1G port into 10G, but for legacy Gigabit interfaces it gives a clean, cost-conscious way to use a long CWDM span. The standard SFP MSA form factor seated properly, and the SFF-8472 DOM data integrated into our normal monitoring workflow.

We deployed 18 units of the LS-CW451G-80C in a municipal campus network connecting branch buildings to a central data room. The longest fiber section was just under 73km after splice and patch-panel losses, so we selected the 80km CWDM 1G SFP to retain reasonable margin. Initial DDM readings showed TX around the expected range and receiver levels comfortably above the sensitivity threshold. After several weeks, interface counters remain clean with no observed packet loss or CRC growth.

We used this LS-CW451G-80C 1450nm CWDM SFP to extend a 1G link between two campus buildings. The 80km rating gave us plenty of optical margin on our much shorter single-mode fiber route, and the duplex LC connector made replacement straightforward.

We evaluated a pair on a long enterprise fiber route that includes multiple fusion splices, distribution frames, and CWDM passive components. The 1450nm channel passed traffic continuously during a 72-hour soak test, while optical diagnostics remained consistent with the calculated loss budget. The -26dBm receiver sensitivity is useful for these longer links, although we still recommend validating actual attenuation and keeping appropriate engineering margin. This is a good commercial-temperature 80km CWDM SFP for indoor network cabinets and managed backbone sites.

This was purchased for a 1G base-station backhaul extension where available fiber was limited and the wavelength plan could not be changed. The module’s 1450nm CWDM wavelength allowed us to add capacity without deploying additional fiber pairs. We monitored DOM values during peak utilization and saw no abnormal drift in transmit or receive levels. The unit is commercial-grade rather than industrial temperature rated, so we installed it inside a conditioned enclosure as planned; for that environment, performance has been excellent.

Great module for point-to-point Gigabit links where trenching new fiber wasn't an option. Adding this 1450nm wavelength channel into our existing CWDM filter allowed us to spin up a dedicated backup link across 68km. Solid optical link stability over 30 days of continuous traffic.

Our operations team used these modules in a CWDM transport overlay for several 1GbE aggregation links. The key requirement was a 1450nm DFB CWDM transmitter compatible with our existing passive MUX/DEMUX channel map, plus readable SFF-8472 diagnostics. During acceptance testing, we checked temperature, voltage, laser bias, TX power, and RX power on both ends; the readings were consistent across the shipment. For commercial indoor racks operating within 0–70°C, this has been a dependable long-distance 1G SFP optical transceiver.
