Support long-reach 10 Gigabit Ethernet connections with the AddOn 455886-B21-AO TAA-compliant 10GBASE-LR SFP+ transceiver. Designed for single-mode fiber, this module uses a 1310 nm wavelength and LC connectivity to deliver up to 10 km of reach for enterprise uplinks, distribution links, and inter-building runs. For procurement teams working under TAA requirements, compliance matters as much as performance. This module gives you a standards-based optical path without forcing compromises on distance or port density. The SFP+ form factor keeps deployment simple in compatible switches and routers, while the LR profile is the right choice when the network must span more than a rack or a room. Compared with shorter-reach optics, this module is built for environments where the cost of a failed link is higher than the cost of the transceiver itself. It is a practical fit for regulated networks, standardized fiber plants, and infrastructure teams that need long-reach 10 GbE with clear sourcing requirements.
