Description

The Arista OSFP-800G-2PLR4 is an 800Gbps OSFP optical transceiver module engineered for high-performance data centre interconnects up to 10km over single-mode fibre. Utilising eight parallel 100Gb/s channels with PAM4 modulation at 1310nm wavelength and dual MPO-12 APC connectors, this transceiver supports breakout configurations to 2x 400G-PLR4 or 8x 100G-LR, making it ideal for spine-leaf architectures and multi-tier network deployments. It complies with OSFP MSA and IEEE 802.3 standards and features Digital Diagnostics Monitoring (DDM) for real-time performance tracking.

Features

Eight-lane 100Gb/s PAM4 electrical signalling per OSFP MSA specification
- Dual-port optical architecture supporting 2x 400G or 8x 100G breakout topologies
- Long-reach 10km transmission over industry-standard G.652 single-mode fibre
- Hot-pluggable OSFP form factor with finned heatsink for efficient thermal management
- Real-time Digital Diagnostics Monitoring (DDM) for proactive health monitoring
- Low-latency operation suitable for high-frequency trading and real-time analytics
- IEEE 802.3ck 800GBASE Ethernet compliance ensuring standards-based interoperability
- Backwards-compatible breakout to existing 100G and 400G network infrastructure
- Advanced PAM4 signalling technology for high spectral efficiency
- Commercial temperature range operation for standard data centre environments

FAQs

Q: What network configurations does the OSFP-800G-2PLR4 support?
A: This transceiver supports native 800G point-to-point links up to 10km, or can break out to 2x 400G-PLR4 or 8x 100G-LR connections, enabling flexible spine-leaf topologies and migration paths from 100G and 400G infrastructure.

Q: Is this transceiver compatible with non-Arista equipment?
A: Yes, the OSFP-800G-2PLR4 follows OSFP MSA and IEEE 802.3 standards, ensuring optical interoperability with any vendor's 400G-PLR4 or 100G-LR transceivers on the remote end, though host system compatibility should be verified for non-Arista platforms.

Q: What type of fibre cable is required?
A: The transceiver requires single-mode fibre (SMF) with dual MPO-12 APC connectors, typically using 8-fibre or 12-fibre MTP/MPO trunk cabling for the 10km parallel optics transmission.

Q: Does this module require a specific software version?
A: For Arista platforms, consult the Arista Transceiver Compatibility Guide for minimum EOS version requirements. Generally, recent EOS releases (4.29+ and later) support 800G OSFP optics.

Q: What is the typical use case for this transceiver?
A: Ideal for hyperscale data centre spine-to-leaf interconnects, AI/ML cluster networking, high-performance computing fabrics, and cloud infrastructure requiring 800G throughput with medium-distance reach and breakout flexibility.
