Description
The AddOn SFP-16GB-DW21-40-AO is a high-performance, MSA-compliant 16GBase-DWDM Fibre Channel SFP+ transceiver designed for reliable and scalable optical networking over single-mode fiber (SMF). Operating at a 1560.61 nm wavelength (DW21, 100 GHz), it delivers data rates up to 16 Gbps and supports transmission distances of up to 40 km, making it ideal for access, metro, and enterprise applications.
Built with a cooled EML transmitter and PIN receiver, this hot-pluggable module features a duplex LC connector and includes Digital Optical Monitoring (DOM) support for real-time performance monitoring. It complies with TAA, RoHS, and SFF-8432/8472 standards and undergoes extensive serialization, data-traffic, and application testing to ensure seamless network integration. Backed by AddOn’s limited lifetime warranty, it’s a cost-effective and dependable alternative to OEM optics.
