Description
The AddOn SFP-16GB-DW21-40-C-AO is a Cisco® compatible TAA-compliant 16GBase-DWDM Fibre Channel SFP+ transceiver designed for high-performance data transmission over single-mode fiber (SMF) at distances up to 40 km. Operating on the DWDM ITU Channel DW21 (1560.61 nm) with a 100 GHz channel spacing, this transceiver delivers reliable connectivity for demanding 8x/10x Fibre Channel and 16G Gigabit Ethernet over DWDM applications across access, metro, and enterprise networks.
Featuring a cooled EML transmitter and PIN receiver, it ensures exceptional signal integrity and performance. The unit is hot-swappable, fully SFF-8432/SFF-8472 compliant, and supports Digital Optical Monitoring (DOM) for real-time diagnostics. Rigorously tested for interoperability, serialization, and traffic performance, it is guaranteed to perform identically to the OEM part. With robust ESD protection, low EMI design, and RoHS compliance, this transceiver ensures long-term network reliability backed by a limited lifetime warranty.
