What are the differences between Flat Top modules and Finned Top modules?

Flat Top module's height is 9.5 mm without heat sinks, relying on the heatsinks on the NIC ports to assist the module in cooling, which fits into compact or constrained spaces without interference. Finned Top modules feature a top design equipped with heat dissipation fins. The integrated top heatsink enhances cooling efficiency when handling massive data.

Description

NVIDIA/Mellanox Original MMA4Z00-NS Twin-port Transceiver, 800Gbps, 2xNDR, OSFP, 2xMPO, 850nm MMF, SR8, up to 50m

NVIDIA/Mellanox Original MMA4Z00-NS is an InfiniBand and Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, SR8 multimode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb/s each. The parallel multimode, short reach 8-channel (SR8) uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using 8 multimode fibers.The Quantum-2 and Spectrum-4 switches require finned-top OSFP shells for extra transceiver cooling. The main application for MMA4Z00-NS is linking two switches together with up to 50-meter transceivers.

Questions & Answers

Ask a Question

What kind of optical fiber do I need to use with the MMS4X00-NS optical module?

When the connection rate of both devices is 2x400G-2x400G, it is paired with two OM4 MPO-12/APC patch cords. When the connection rate of both devices is 2x400G-4x200G, it is paired with two multimode OM4 MPO-2xMPO-4/APC patch cords.

Why is the polished type of multimode patch cable used in the NDR module MPO/APC (Angled Polished Connector)?

100G-PAM4 optoelectronic devices are very sensitive to reflections occurring within the fiber, about 10% of the light is reflected back to the transmitter as it passes through the optical connector, distorting the data signal, APC's optical connector deflects this reflected light.

What is the modulation method of the MMS4X00-NS optical module?

8-channels of 100G-PAM4 electrical modulation, Two ports of 4-channel 100G-PAM4 optical modulation.
