Key Features of H3C SFP-GE-LH40-SM1450-CW Compatible LINK-PP 1.25G SFP
H3C SFP-GE-LH40-SM1450-CW Compatible LINK-PP module is a commercial-grade SFP transceiver that bundles essential features for reliable fiber links. It supports a 1Gbps data rate over a 1450nm CWDM channel, reaches 40km on single-mode fiber, and uses a duplex LC connector. The module also includes digital optical monitoring (DOM) and fully complies with the SFP MSA for hot-swappable operation.
This 1G CWDM module follows the standard hot-pluggable SFP footprint, enabling installation or replacement without powering down the host equipment. It is fully compliant with the SFP MSA, guaranteeing mechanical and electrical interoperability with most commercial switches and routers.
SFP-GE-LH40-SM1450-CW: 1 Gbps Connectivity for Long-Haul Enterprise Backbones
The transceiver provides a steady 1Gbps line rate, which is well suited for enterprise backbone links that span extended campus or metropolitan areas. Its speed meets the bandwidth demands of corporate data traffic over long distances.
SFP-GE-LH40-SM1450-CW Module with CWDM Technology for Fiber Efficiency
The CWDM implementation allows multiple wavelengths to be combined onto a single strand of fiber, significantly improving the utilization of existing cabling. It reduces the number of physical fibers needed in dense network topologies, lowering overall infrastructure costs.
SFP-GE-LH40-SM1450-CW Module with 1450nm Wavelength
The 1450nm wavelength is part of the standard CWDM grid, offering a stable transmission window with low attenuation in typical single-mode fibers. This specific channel avoids crosstalk with adjacent wavelengths, making it a reliable choice for multiplexed systems.
This module’s 40 km reach over single-mode fiber covers most metro-area and inter-building connections. It maintains sufficient optical power budget to ensure error-free data delivery at that distance.
SFP-GE-LH40-SM1450-CW Module with Duplex LC Interface
The duplex LC interface provides a compact, secure, and polarity-clear connection for standard fiber patch cords. It facilitates easy integration into existing patch panels and reduces the risk of misinsertion during field deployment.
SFP-GE-LH40-SM1450-CW Module with DOM for Real-Time Monitoring
Real-time monitoring is delivered through the built-in DOM function, which tracks Rx optical power, Tx optical power, temperature, supply voltage, and laser bias current. This functionality is compatible with SFF-8472, allowing network hosts to read diagnostic parameters via the usual I²C bus for proactive maintenance.

Purchased multiple units for our metro-Ethernet distribution ring and put them through a full month of rigorous production testing across various single-mode fiber routes. The transceiver handshakes immediately with our core hardware, delivering consistent Gigabit transmission speeds without thermal throttling. The dynamic range on the receiver is versatile enough to support both mid-range and full-distance links without overloading or signal degradation. Everything from the great optical clarity to the durable metal housing meets our high data center reliability standards. Truly excellent enterprise optics that perform far above their price point.

Our team needed to establish a dedicated Gigabit uplink between two corporate facilities across dark fiber without leasing extra fiber pairs. This 40km duplex LC transceiver locked onto the 1450nm channel instantly through our passive Mux/Demux filters and standard OS2 patch cables. The mechanical latch is smooth to operate during hot-plugging, and the optical link headroom easily handled our multiple patch panel transitions along the route. We have seen zero CRC faults or link flapping since commissioning last month. These optics deliver true carrier-grade stability for long-haul enterprise connections. (^_^)

The 1450nm CWDM SFP works perfectly on our 30km fiber link. It was instantly recognized by our switch. The only reason for 4 stars is that the shipping took a few days longer than the estimate. The product itself is flawless.
