QSFP-100G-ZR4-S Cisco Compatible 100G QSFP28 80km SMF Transceiver

At 80km over single-mode fiber, the QSFP-100G-ZR4-S pushes 100 Gigabit across the kind of inter-site and metro spans where the link has to leave the building. Housed in the QSFP28 form factor and terminated in a duplex LC, it seats in a standard cage and comes up on Cisco platforms as a recognized module with no host configuration. Live optical readings stream over DDM for monitoring the 80km span.
