This transceiver is a high-performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 100Gbps bandwidth. Each lane can operate at 25Gbps up to 70m using OM3 fiber or 100m using OM4 fiber. They are compliant with the QSFP28 MSA1 and IEEE 802. The transceiver is. The Cisco 100GBASE Quad Small Form-Factor Pluggable (QSFP) portfolio offers customers a wide variety of high-density and low-power 100 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider. A 100BASE FX SFP transceiver enables Fast Ethernet transmission over multimode fiber, typically operating at 1310nm and supporting distances up to 2km. Compared with copper-based 100BASE-TX connections, it offers stronger EMI immunity, longer reach, and improved reliability in electrically noisy. Mellanox® MMA1B00-C100D is a 4-channel, pluggable, QSFP28 optical transceiver designed for use in 100GbE Ethernet. Featuring an LC style connector, it supports 100BaseFX Ethernet over multimode fiber for distances up to 2 kilometers, providing a reliable fiber optic connection.
