Description

The Arista OSFP-800G-2PLR4 is an 800 Gigabit OSFP optical transceiver designed for high-speed data center interconnects up to 10km over single-mode fiber. It supports 800GBASE-PLR8 with 8 channels of 100Gb/s PAM4 modulation, delivering aggregate 800Gb/s throughput via dual MPO-12 connectors at 1310nm wavelength. This module enables flexible breakout options to 2x 400G-PLR4 or 8x 100G-LR configurations, making it ideal for spine-leaf architectures, hyperscale cloud data centers, and AI/ML workloads requiring extended reach and reliable performance.

FAQs

Q: What is the maximum transmission distance for the OSFP-800G-2PLR4?
A: The OSFP-800G-2PLR4 supports transmission distances up to 10km over single-mode fiber using 1310nm wavelength CWDM4 optics.

Q: Can this transceiver be broken out to lower-speed configurations?
A: Yes, the OSFP-800G-2PLR4 supports breakout to 2x 400G-PLR4 connections or 8x 100G-LR links, providing flexible deployment options for mixed-speed network architectures.

Q: Is the OSFP-800G-2PLR4 compatible with QSFP-DD ports?
A: No, OSFP and QSFP-DD are physically distinct form factors with different dimensions. OSFP modules require OSFP-compliant ports, though the optical signals can interoperate with QSFP-DD modules of the same type via fiber connections.

Q: What fiber type is required for the OSFP-800G-2PLR4?
A: This transceiver requires OS2 single-mode fiber (SMF) with MPO-12 or MPO-16 connectors (APC polished) for optimal 10km reach and signal integrity.

Q: Does this module support digital diagnostics monitoring?
A: Yes, the OSFP-800G-2PLR4 includes full DDM/DOM capabilities, enabling real-time monitoring of optical power, temperature, transmit bias current, and supply voltage for proactive network management.
