Key Features of FS CW-SFP10G40-35-I Compatible LINK-PP 10.7G SFP+

FS CW-SFP10G40-35-I Compatible LINK-PP module is an industrial-grade CWDM 10G SFP+ optical transceiver designed for dependable 40km transmissions over single-mode fiber. It combines a 1350nm wavelength with a duplex LC interface and real-time diagnostic monitoring to optimize fiber capacity. Built for demanding temperature environments, it delivers steady 10Gbps connectivity across modern metro and telecom networks.

FS CW-SFP10G40-35-I Compatible LINK-PP 10G SFP+ Optical Module

Built in a hot-pluggable SFP+ footprint, this module enables quick installation and upgrades without interrupting active network operations. It strictly complies with SFP+ MSA and SFF-8472 standards, ensuring smooth hardware interoperability with standard host devices. This compliance makes it a flexible choice for expanding enterprise and telecom infrastructures.

CW-SFP10G40-35-I: 10 Gbps Connectivity for Long-Reach Metro Networks

Delivering a full 10Gbps line rate, this transceiver supports bandwidth-intensive data transport over extended physical distances. It is well-suited for linking distant sub-stations, enterprise campuses, and regional metro aggregation nodes. This steady line-rate performance ensures seamless data flow across demanding long-reach optical paths.

CW-SFP10G40-35-I Module with CWDM Technology for Fiber Efficiency

Utilizing Coarse Wavelength Division Multiplexing (CWDM), this transceiver allows multiple data channels to run over the same fiber cable. This capability maximizes existing strand usage without the need to lay costly new fiber lines. It offers an economical path for network operators looking to multiply their total carrying capacity.

CW-SFP10G40-35-I Module with 1350nm Wavelength

Operating on a precise 1350nm center wavelength, the module integrates cleanly into multi-channel CWDM grid layouts. Its dedicated channel frequency prevents signal crosstalk with neighboring optical wavelengths. This accurate spectral targeting ensures crisp optical signaling across long-distance links.

CW-SFP10G40-35-I Module Supporting 40km Transmission

Equipped with a cooled EML laser and PIN receiver, this module achieves reliable point-to-point links up to 40km over single-mode fiber.

We installed these CWDM SFP+ modules to connect security systems, flight displays, and baggage handling across three terminals. The 1350nm CWDM channel fits our existing wavelength plan without conflicts. The industrial temperature rating handles our rooftop equipment enclosures through seasonal extremes. DDM monitoring lets our network team check link status remotely without site visits. After 2 months of 24/7 operation, all 22 units are still performing flawlessly. The 40km reach easily covers our entire airport campus.
