Overview
Product overview
The MMS4X00-NS400 is a single-port OSFP transceiver supporting both InfiniBand NDR and 400GbE protocols with auto-detection. Its flat-top housing mates with ConnectX-7 adapter riding heatsinks, utilizing a single MPO-12/APC optical connector with four transmit and four receive fibers powered by 1310nm EML lasers.
Key features
- 400Gb/s Data Rate: 4x 100G-PAM4 modulation, DR4 single-mode: Dual Protocol Support: InfiniBand NDR and 400Gb Ethernet auto-detection
- 100m Reach: Single-mode fiber with two patch panels assumed: Low Power Operation: 9W max (400G) / 5.5W max (200G) / 1.5W sleep
- Automatic Speed Reduction: Self-configures to 200Gb/s with 1:2 splitter cables
- Flat-Top OSFP Design: Riding heatsink compatibility for ConnectX-7: CMIS 4.0 Compliant: DDM, loopback, PRBS generator, field upgrade capability
- Class 1 Laser Safety: RoHS compliant, hot-pluggable, 0°C to +70°C operating range
Typical applications
- 25G / 100G / 400G / 800G optical links
- Switch-to-adapter interconnect
- Rack-to-rack optical deployment
