Description

The Arista OSFP-400G-PLR4-S is a 400GBASE-PLR4 OSFP transceiver designed for high-density data centre and cloud network deployments requiring long-reach parallel single-mode fibre connectivity up to 10km. Operating across four 100GBASE-LR lanes at 1310nm, it supports breakout to 4x 100G and delivers full optical interoperability with 4x 100GBASE-LR QSFP transceivers — making it a flexible backbone component in spine-leaf and hyperscale fabrics.

Equipped with SN optical connectors for superior cabling density compared to standard MPO-12 APC variants, this transceiver features an 8x 50Gb/s PAM-4 electrical interface (400GAUI-8), CMIS 4.0 management, and Digital Optical Monitoring (DOM) for real-time diagnostics. Hot-pluggable and rated for 0°C to 70°C operating environments, it integrates seamlessly into Arista 400G platforms. Need it fast? iptrading.com.au delivers across Australia — shop now.

FAQs

Q: What fibre type and reach does the OSFP-400G-PLR4-S support?
A: The OSFP-400G-PLR4-S operates over parallel single-mode fibre (SMF) at 1310nm across 4 lanes, supporting link distances up to 10km — making it suitable for intra-campus and data centre interconnect applications.

Q: Can this transceiver break out to 4x 100G connections?
A: Yes. The OSFP-400G-PLR4-S supports breakout to 4x 100GBASE-LR, and is optically interoperable with 4x 100GBASE-LR QSFP transceivers up to 10km, providing flexible connectivity options for mixed-speed environments.

Q: What does the SN connector offer compared to MPO-12 APC?
A: SN connectors are a duplex push-pull design that provides approximately double the port density of MPO-12 APC connectors in the same panel space, making them ideal for high-density data centre cabling infrastructure.

Q: Which Arista platforms are compatible with this transceiver?
A: The OSFP-400G-PLR4-S is designed for Arista switches and routers with OSFP ports supporting 400G, such as platforms in the 7050X4, 7060X5, and 7800 series. Always verify compatibility with your specific Arista platform's transceiver support matrix.

Q: Does the OSFP-400G-PLR4-S support Digital Optical Monitoring?
A: Yes. DOM is fully supported, allowing network operators to monitor real-time parameters such as optical transmit/receive power, temperature, and supply voltage via the CMIS 4.0 management interface.

Q: Can I purchase the Arista OSFP-400G-PLR4-S in Australia through IP Trading?
A: Yes. IP Trading is an Australian B2B IT hardware reseller stocking Arista transceivers and optics. The OSFP-400G-PLR4-S is available through iptrading.com.au with delivery across Australia.
