NVIDIA/Mellanox MFP7E40-Nxxx Compatible Single-mode MPO Splitter Fiber Cable
NVIDIA/Mellanox MFP7E40-Nxxx Compatible Singlemode Splitter Fiber Cable (8 Fibers MPO to 2xMPO 4 Fibers, 9/125um, Low Insertion Loss: <0.35dB, 8 to 2x4 Cores, Type B, MPO female connector without Pins )
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.
