Description

The 400GBASE-SR8 OSFP transceiver delivers 400Gbps aggregate throughput across 8 parallel optical channels, each running at 50Gb/s PAM4, over an MPO-16 APC connector. Designed for short-reach data centre and cloud network deployments, it supports up to 100 metres over parallel OM4 multimode fibre — making it ideal for high-density spine-leaf and top-of-rack interconnects on Arista 400G and 800G switch platforms.

Software configurable for 400G-SR8, 2x 200G-SR4, or 2x 100G-SR4 operation, this transceiver offers exceptional deployment flexibility without hardware changes. The gearbox-free design delivers low latency direct electrical-to-optical conversion, while Digital Diagnostic Monitoring (DDM/DOM) enables real-time performance visibility. RoHS compliant and hot-pluggable, it meets IEEE 802.3bs and OSFP MSA standards. In stock and ready to ship from iptrading.com.au — order now for fast dispatch.

FAQs

Q: What fiber type and cable is required for the OSFP-400G-SR8?
A: This transceiver requires parallel OM4 multimode fibre with an MPO-16 APC connector. It uses 16 fibres total (8 transmit, 8 receive) and supports a maximum reach of 100 metres over OM4 MMF. OM3 MMF can also be used but will yield a reduced reach of approximately 70 metres.

Q: Can this transceiver be used in breakout mode?
A: Yes. The OSFP-400G-SR8 is software configurable to support 2x 200G-SR4 or 2x 100G-SR4 breakout operation in addition to native 400G-SR8 mode. This makes it highly flexible for connecting to lower-speed downstream devices without requiring additional hardware.

Q: Which Arista switch platforms are compatible with the OSFP-400G-SR8?
A: This transceiver is designed for use with Arista switch platforms that feature OSFP ports, including 400G and 800G data centre switches such as the Arista 7800R3 and 7060X5 series. Always verify compatibility with your specific Arista EOS version and hardware platform.

Q: Does the OSFP-400G-SR8 support Digital Diagnostic Monitoring?
A: Yes. The transceiver supports Digital Diagnostic Monitoring (DDM/DOM), allowing real-time visibility into optical parameters including transmit/receive power, temperature, supply voltage, and laser bias current directly through the host system management interface.

Q: Is the OSFP form factor different from QSFP-DD?
A: Yes. OSFP and QSFP-DD are both 400G form factors but are physically distinct and not interchangeable. OSFP is slightly larger, supports higher power dissipation (up to 15W), and is designed for next-generation 400G and 800G platforms. Always ensure your switch has OSFP ports before ordering.

Q: Can I purchase the Arista OSFP-400G-SR8 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller with the OSFP-400G-SR8 in stock and ready for fast dispatch. Contact us for volume pricing, compatibility advice, or to discuss deployment requirements for your data centre or cloud network project.
