The Tellabs 81.71T-SPMRLR2-R6 is a long-reach (LR) SFP optical transceiver module designed for the Tellabs / Coriant 7100 Nano platform. It enables high-speed optical communication over extended distances, making it ideal for metro, inter-office, and backbone fiber networks.
This module converts electrical signals to optical signals for transmission over single-mode fiber, supporting carrier-grade performance in telecom and data center environments. The LR variant is optimized for longer fiber links compared to standard short-range SFP modules.
