Keep critical 10 GbE links stable across longer fiber runs with this AddOn compatible XFP transceiver for Avaya/Nortel AA1403001-E5 deployments. Designed for Nortel Ethernet Routing Switch 5600 Series compatibility, it delivers 10GBase-LR performance over single-mode fiber with up to 10 km reach at 1310 nm. The LC interface and hot-swappable XFP form factor make it straightforward to deploy in production environments where downtime is not an option. TAA compliance supports procurement requirements for public sector and regulated buyers, while the low-power design helps reduce thermal load in dense switch environments. Each module is programmed, serialized, and tested to meet or exceed OEM expectations, which matters when the cost of a failed optic is measured in service disruption, not just replacement price. For teams standardizing on proven optics rather than overpaying for branded equivalents, this module offers a practical balance of compatibility, reach, and operational confidence.
