Key Features of HPE SFP40K-CW1610 Compatible LINK-PP 1.25G SFP
HPE SFP40K-CW1610 Compatible LINK-PP module is a 1G SFP transceiver that integrates CWDM technology, 1610nm wavelength, 40km reach, duplex LC interface, and digital optical monitoring (DOM) into a hot-pluggable MSA-compliant package. It operates over single-mode fiber and delivers real-time diagnostic data through its DOM function. These combined features make it a versatile option for medium-to-long distance fiber links.
This SFP transceiver adopts a hot-pluggable SFP footprint that allows quick installation and replacement without system shutdown. It is fully compliant with the SFP Multi-Source Agreement (MSA), ensuring mechanical and electrical interoperability with standard cages and host boards.
SFP40K-CW1610: 1 Gbps Connectivity for Metro Edge Access Spans
Operating at a 1Gbps data rate, this module provides reliable connectivity for metro edge access spans where bandwidth demand is moderate. It handles typical uplink and aggregation tasks in campus or city-edge networks with ease.
SFP40K-CW1610 Module with CWDM Technology for Fiber Efficiency
The CWDM technology embedded in this module enables multiple wavelengths to share a single physical fiber, reducing the number of fibers needed for network expansion. By using coarse wavelength division multiplexing, it helps operators make better use of existing dark fiber infrastructure.
SFP40K-CW1610 Module with 1610nm Wavelength
This transceiver operates on the 1610nm CWDM channel, which lies in the longer-wavelength window of the standard single-mode fiber transmission band. That wavelength is selected to minimise attenuation and to align with common CWDM multiplexer/demultiplexer grids.
SFP40K-CW1610 Module Supporting 40km Transmission
The module supports fibre transmission distances up to 40km, with an optical power budget sufficient to overcome typical fibre losses at 1610nm over that length. It is designed for single-mode fibre and maintains signal integrity across the full 40km span.
SFP40K-CW1610 Module with Duplex LC Interface
The duplex LC connector is used on the module’s optical interface, providing a secure and standardised connection for dual-fibre patch cords. This interface is widely deployed in telecom and enterprise environments, ensuring compatibility with most fibre distribution panels.
SFP40K-CW1610 Module with DOM for Real-Time Monitoring
Digital optical monitoring (DOM) gives this module the ability to track key operating parameters in real time. It is compatible with SFF-8472 digital diagnostics functions, reporting transmitter power, receiver power, operating temperature, supply voltage, and laser bias current continuously.
The HPE SFP40K-CW1610 Compatible LINK-PP 1G SFP transceiver is manufactured in compliance with strict international industrial standards. It holds key certifications including ISO 9001, CE, RoHS, and FCC to guarantee product quality and environmental safety.
Every optical transceiver undergoes rigorous functional and temperature testing prior to shipment. These evaluations verify signal integrity and operational stability under varying conditions.

A:
Fiber attenuation at 1610nm is slightly higher than at 1550nm, but significantly lower than 1310nm. However, macro-bending losses are more noticeable at 1610nm, so ensure standard fiber bend radius guidelines are maintained. By

A:
In most standard deployments, yes. The 40km design generally provides enough optical margin to handle the fiber distance plus typical filter insertion loss. However, since actual fiber quality and splice counts vary, we always recommend verifying your total route loss against the module's optical power budget before final turn-up. By

Good performance for the price point. We've had these running in a test lab for 6 weeks — no thermal issues, no CRC errors. The -26 to -1dBm RX power range gives us flexibility for varying fiber losses. Would buy again for our CWDM links.

Leasing additional dark fiber pairs between our HQ and backup data center was cost-prohibitive, so we deployed passive CWDM multiplexers. We needed a dedicated 1610nm 1G transceiver to complete our 8-channel topology. The LS-CW611G-40C SFP module integrated seamlessly into our switch uplinks. Latch release is sturdy, duplex LC connectors fit snugly, and the SFF-8472 compliance ensures standard diagnostic alarms trigger properly. Over a 27km route with multiple fusion splices, we achieved a sustained 1.25Gbps throughput with zero frame loss or jitter.

The 1610nm CWDM module itself works like a charm on our 30km fiber link with great DDM readings. Knocking off one star because the delivery was delayed by two days due to customs clearance. Optic is solid though!
