Belden FC4U03SDMF FX Ultra Cassette, OM4, 3-Port, MPO12(F)

Optimize high-density backbone and data center connectivity with the Belden FC4U03SDMF fiber optic cassette. This Fiber Optic Cassette is engineered to simplify trunk-to-panel transitions and speed installations in data centers, main distribution rooms and telecommunications rooms. The OM4 multimode design delivers enhanced bandwidth and reach for demanding applications, while the 3-port MPO12(F) interface supports multi-fiber trunking for efficient, scalable networking.

Designed for indoor use and a compact footprint (4.5 in W x 1.5 in H, 6.6 in length), the cassette conserves valuable rack space and streamlines patching workflows. The purple OM4 color coding helps teams quickly identify multimode circuits, reducing downtime during maintenance or expansions. Ideal for security, surveillance and monitoring systems, the FC4U03SDMF integrates with FiberExpress infrastructure to provide predictable, low-loss performance for mission-critical connectivity.
