Description
The AddOn SFP-25GB-CW-29-40-AO is a high-performance, MSA and TAA compliant 25GBase-CWDM SFP28 transceiver designed for reliable data transmission in demanding network environments. Operating over single-mode fiber (SMF) with a center wavelength of 1290nm, this transceiver delivers up to 25.78 Gbps throughput and supports transmission distances of up to 40km via an LC connector.
Built with a CWDM DFB laser and APD receiver, it ensures stable and efficient signal integrity for a variety of applications, including 25G Ethernet, mobile fronthaul (CPRI/OBSAI), and metro or enterprise networking. The module supports digital optical monitoring (DOM), providing real-time access to critical operating parameters, and is rigorously tested for seamless integration and optimal performance. With a low power consumption of 2.0W and hot-pluggable SFP28 form factor, this transceiver is ideal for scalable, high-speed network infrastructure.
