Description

The Arista OSFP-400G-PLR4 is a 400GBASE-PLR4 OSFP optical transceiver engineered for high-density data centre interconnects requiring long-reach parallel single-mode fibre connectivity. Operating across 4x 100GBASE-LR lanes at 1310nm, it delivers 400Gb/s aggregate bandwidth over standard parallel SMF infrastructure using an MPO-12 APC connector, reaching up to 10km. Its 4x 100G breakout capability and optical interoperability with existing 100GBASE-LR QSFP modules make it an ideal choice for network architects migrating or scaling to 400G without replacing installed fibre plant.

Built to the OSFP form factor with an 8-lane 400GAUI-8 electrical interface (8x 50Gb/s PAM4), this module supports CMIS 4.0 and Digital Optical Monitoring for real-time link diagnostics and simplified operations. Designed for Arista 400G OSFP-based switching platforms, it is hot-pluggable for seamless deployment in production environments.

FAQs

Q: What fiber type and cable infrastructure does the OSFP-400G-PLR4 require?
A: The OSFP-400G-PLR4 requires parallel single-mode fibre (9µm SMF) with an MPO-12 APC connector. It uses four parallel lanes at 1310nm, making it compatible with widely deployed parallel SMF cabling infrastructure in enterprise and data centre environments.

Q: Can the OSFP-400G-PLR4 break out into multiple 100G connections?
A: Yes. The module supports 4x 100G breakout mode and is optically interoperable with standard 4x 100GBASE-LR QSFP modules, enabling flexible connectivity and gradual migration from 100G to 400G infrastructure without replacing installed fibre.

Q: Which Arista platforms is this transceiver compatible with?
A: The OSFP-400G-PLR4 is designed for Arista switching platforms with OSFP ports, including 400G data centre switches in the Arista 7800, 7500, and 7000 series that support OSFP-based 400G interfaces.

Q: Does this transceiver support Digital Optical Monitoring?
A: Yes. The OSFP-400G-PLR4 includes Digital Optical Monitoring (DOM) and complies with CMIS 4.0, providing real-time visibility into optical power levels, temperature, voltage, and bias current for simplified troubleshooting and proactive link management.

Q: Can I purchase the Arista OSFP-400G-PLR4 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller supplying Arista transceivers and networking hardware with expert pre-sales support and fast local fulfilment. Contact us or visit the product page to place your order.

Q: What is the maximum transmission distance supported by this module?
A: The OSFP-400G-PLR4 supports a maximum reach of 10km over parallel single-mode fibre, making it suitable for campus backbone, inter-building, and data centre interconnect scenarios requiring long-reach 400G connectivity.
