Keep critical network paths open with a transceiver designed for short-reach multimode fiber runs. The Black Box LFP441 delivers 1.25 Gb performance for 1000Base-SX environments and supports dual-rate operation at 1.063/2.125 Gb/s, making it a practical fit for mixed infrastructure where compatibility matters. Its LC connector and SFP form factor suit high-density equipment where port space is limited and clean cable management matters. With support for up to 550 m over multimode fiber, it covers common campus, aggregation, and equipment-room links without forcing a move to more expensive optics. This module is also aligned to fiber channel and wireless transport use cases, including CPRI, OBSAI, and LTE-related deployments. For teams standardizing on proven short-reach optics, it offers the right balance of reach, interoperability, and deployment simplicity.
