# NVIDIA MMA4Z00-NS400 Compatible 400G OSFP SR4 Flat Top PAM4 850nm 30m on OM3/50m on OM4 MTP/MPO-12 Multimode FEC Optical Transceiver Module #### NVIDIA MMA4Z00-NS400 Compatible 400G OSFP SR4 Flat Top PAM4 Optical Transceiver Module (850nm MTP/MPO12 OM3/OM4 50m with FEC DDM) #### Cisco compatible 400G transceivers ![](https://cdn.shopify.com/s/files/1/0758/0362/3703/files/dft2025112218.webp?v=1763803289) This product is a 400Gb/s Octal Small Form-factor Pluggable (OSFP) optical module without a top open fin designed for 50m with OM4 fiber optical communication applications. The module converts 4 channels of 100Gb/s (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s. On the receiver side, the module converts 4 channels of parallel optical signals of  100Gb/s each channel for an aggregate data rate of 400Gb/s into 4 channels of 100Gb/s (PAM4) electrical output data. MPO-12 connector can be plugged into the OSFP112 SR4 module jack with 4 channels. The guide pins inside the receptacle ensure proper alignment. The cable usually cannot be twisted for adequate channel-to-channel alignment. The electrical connection is achieved through an OSFP MSA-compliant edge-type connector. The I2C interface supports reading and controlling this product's status. ### Product Details NVIDIA Compatible MMA4Z00-NS400 Vendor Name DFTTELECOM Form Factor OSFP Max Data Rate 425Gbps Wavelength 850nm Max Distance 30m on OM3/50m on OM4 Modulation Format PAM4 Host Required FEC Connector MPO-12 (APC) Voltage Supply 3.3V Cable Type MMF DDM Support  Yes Transmitter Type  850nm VCSEL Receiver Type  PIN TX Power \-4.6~+4.0dBm Receiver Sensitivity < -4.6dBm Operation Temperature  0 to 70°C (32 to 158°F) Maximum Power < 8W Protocols OSFP MSA, IEEE 802.3bs Application                                                 2x400G to 400G Links                           400GIB/EN Switches to 2 Connectx-7 and BIueField-3 ![](https://cdn.shopify.com/s/files/1/0758/0362/3703/files/dft2025112215.png?v=1763801607)                                           400G NDR Switch to NIC Links                       400G NDR Switch to 2x400G NIC Links Using Multi-mode Fiber ![](https://cdn.shopify.com/s/files/1/0758/0362/3703/files/dft2025112216.png?v=1763802104)                     400G QSFP-DD Swtich to 400G OSFP NVIDIA ConnectX-7 NIC Use 400G QSFP-DD SR4 transceivers on the 400G switch and 400G OSFP SR4 transceivers on the 400G switch, connected via MPO Trunk Cables. ![](https://cdn.shopify.com/s/files/1/0758/0362/3703/files/dft2025112217.png?v=1763802666) ### Quality Certifications We control the quality of our products, including our strict qualification of manufacturers, quality control process and production technology, and compliance with certification and safety standards.
