FH-400G-ZR FiberHome Compatible 400G QSFP-DD ZR 80km SMF Transceiver

FH-400G-ZR is a 400G coherent ZR module in the QSFP-DD form factor, rated for spans up to 80km over single-mode fiber and coded for FiberHome platforms. The line side terminates in a duplex LC connector, and the host reads the module as the FiberHome part it replaces, so commissioning amounts to seating it in the port.

Compatibility: Coherent 400G/800G modules are host-dependent — support varies by chassis, line card, port, airflow, and software release. This compatible module is coded per order for your platform — add your switch model and OS release in the order notes, or email 10.4@tenfouroptics.com, and we confirm coding before it ships.

Tested & Proven: Every TenFour Optics part is coded, tested, and verified before shipment — see Tested & Proven.

An 80km coherent reach puts this optic on the site-to-site spans where 400G has to leave the facility. DDM/DOM diagnostics report optical performance throughout operation. Conformance testing against the QSFP-DD MSA, plus coding and cleanliness verification, precedes every shipment. This module is covered by the GreenLights4Life® Limited Lifetime Replacement Warranty.
