Introduction
The NVIDIA MFP7E40-Nxxx, is a single mode, 4-channel-to-two 2-channel splitter fiber cable. It uses 8 active fibers to transmit light and 4 inactive fibers used as strength members enabled by the Multiple-Push-On, 12 fiber, Angled-Polished-Connectors (MPO-12/APC) optical connectors. The Angled Polished Connector has a 7-degree polish angle to deflect internal optical back reflections from entering the transceiver and distorting the signal quality.
The 4-channel end is inserted into a Twin port OSFP, 800Gb/s transceiver. The 2-channel ends are inserted into two, single port 400Gb/s OSFP and/or QSFP112 transceivers which with only 2 fibers results in 200G rates. Two splitter fiber cables are used in the Twin port OSFP transceiver enabling four, 2-channel ends to four transceivers.
The fibers are “crossover”, Type-B cables enabling directly attaching two transceivers together and aligning the transmit laser fiber on pin 1 to “crosses over” to align with pin 12 of the opposite fiber end transceiver photodetector.
Typically use is linking OSFP switches to in ConnectX-7® network adapters and/or BlueField-3® Data Processing Units (DPUs) in compute and storage servers.
Rigorous cable production testing ensures best out-of-the-box installation experience, performance, and durability. Mellanox optical solutions provide short, medium, and long reach scalability for all topologies, utilizing innovative optical technologies to enable high signal integrity and reliability.
