Introduction
The NVIDIA MFP7E20-Nxxx, is a multimode, 4-channel-to-two 2-channel splitter fiber cable. The Multiple Push On, 12 fiber, Angled Polished Connectors (MPO-12/APC) uses 8 active fibers to transmit light and 4 inactive fibers as strength members. The Angled Polished Connector has a 8-degree polished angle to deflect internal optical back reflections from entering the transceivers 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 can output 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 enable directly attaching two transceivers together and allow the transmit laser fiber on pin 1 to “crosses over” and align with pin 12 of the opposite fiber end transceiver photodetector.
The typical usecase 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. NVIDIA’s optical solutions provide short, medium, and long reach scalability for all topologies, utilizing innovative optical technologies to enable high signal integrity and reliability.
