Key Features of NVIDIA/Mellanox OSFP-SR8-400G Compatible LINK-PP 400G OSFP
NVIDIA/Mellanox OSFP-SR8-400G Compatible LINK-PP module is a 400G OSFP optical transceiver designed for short-reach connections over multimode fiber. It features an 850nm operating wavelength, an MPO-16/APC interface, and real-time monitoring to keep network links stable and easy to manage.
This pluggable transceiver complies fully with the OSFP MSA, IEEE 802.3bs protocol, and 400GAUI-8 electrical interface standards. Such broad standard compliance ensures direct plug-and-play interoperability with modern multi-vendor switching platforms.
OSFP-SR8-400G: 400 Gbps Connectivity for Cloud Data Centers
Aggregate bandwidth reaches 400Gbps to handle dense spine-leaf east-west traffic loads efficiently. It provides the low-latency throughput required by modern cloud computing facilities and distributed storage clusters.
OSFP-SR8-400G Module with 850nm Wavelength
An 850nm VCSEL transmitter array delivers cost-effective optical transmission across parallel multimode glass. Operating at this established spectral window minimizes power consumption while maintaining clean signal integrity over short distances.
OSFP-SR8-400G Module Supporting 100m Transmission
Reach capabilities extend up to 100m over multimode fiber, easily covering standard equipment rows. This span makes it an ideal fit for intra-rack and adjacent-cabinet switch uplinks within the server hall.
OSFP-SR8-400G Module with MPO-16/APC Interface
The integrated MPO-16/APC optical receptacle accommodates eight parallel transmit and receive channels in a single compact port. Its angled physical contact design helps control optical return loss across dense patch panel links.
OSFP-SR8-400G Module with DOM for Real-Time Monitoring
Integrated digital optical monitoring (DOM) continuously tracks operating parameters including temperature, bias current, supply voltage, and laser power. Network engineers can leverage these real-time operational diagnostics to detect link degradation before outages occur.

A:
Yes. The electrical interface is 8×53.125 Gb/s PAM4 (400GAUI-8), and the optical side uses 8 parallel 850 nm lanes for 400GBASE-SR8. It delivers full line-rate throughput and is well suited to 400G Ethernet as well as InfiniBand compute and storage fabrics, with overall latency determined by switch ASIC design and fabric configuration. By
admin
A:
Yes. You can continue using your installed OM3 multimode fiber plant. When Forward Error Correction (FEC) is enabled on 400G switch ports in line with IEEE 802.3bs, the LO-M85400-SR8C supports reliable operation up to 100m over OM3 MMF in typical 400GBASE-SR8 deployments. Before finalizing link lengths, confirm your switch’s FEC mode and verify the end-to-end optical loss budget. By
admin
A:
The module expects standard MPO-16 Type-B polarity for direct module-to-module links. Type-B uses a fully reversed mapping with key-up on both ends, ensuring each transmitter channel on one side aligns to the corresponding receiver on the other. Ensure your structured MPO-16 trunk and patch cords maintain this TX-to-RX cross-connection end-to-end. By
admin
A:
Each LO-M85400-SR8C OSFP module has a maximum power consumption of 12 W. Plan chassis power and cooling based on up to 12 W per port; actual draw varies with FEC configuration, traffic load, and ambient temperature. The module is designed for front-to-back airflow, keeping case operating temperatures within the commercial 0°C to 70°C range under sustained load. By
admin
A:
No. This transceiver uses a native 16-fiber MPO-16 interface (8 Tx + 8 Rx) and cannot accept MPO-12 or MPO-24 connectors directly. Use dedicated MPO-16 patch cords (UPC unless your module is specified as APC) or appropriate MPO conversion cassettes/harnesses to interface with existing trunk infrastructure. By
