We use the QSFPTEK 100GBASE-BX80 for long-distance backbone links, and it has proven to be highly reliable. The signal quality remains strong even near the 80 km limit. Although it is more expensive than shorter-reach modules, the performance makes it worthwhile.

This module meets our company's transmission needs. This module supports single-fiber bi-directional communication, which saves a lot of fiber optic resources, and replaces the previous dual-fiber solution in our company's 75km-long transmission link, which directly reduces half of the cabling cost.
