Description

The Arista OSFP-800G-2XDR4 is an 800G OSFP optical transceiver for data centre leaf, spine and AI/ML fabric links up to 2km. It carries two 400GBASE-XDR4 channels, equivalent to eight 100GBASE-FR lanes, over parallel single-mode fibre at 1310nm.

The module uses two MPO-12 APC connectors on G.652 single-mode fibre, with a reach of up to 2km. Transmit power is -2.4 to +4.0 dBm per lane and receive power is -6.4 to +4.5 dBm per lane. Maximum power consumption is 16W, so the host port must support the OSFP 800G power class. It is optically interoperable with 400GBASE-XDR4 optics and with 4 x 100GBASE-FR up to 2km, which allows breakout to 400G or 100G links.

This 2XDR4 variant uses parallel fibre with dual MPO-12 APC connectors and a 2km reach. That separates it from the 2PLR4 variant, which reaches 10km, and the 2FR4 variant, which uses duplex LC connectors. It is designed for Arista 800G OSFP ports and requires single-mode fibre terminated with MPO-12 APC connectors.

FAQs

Q: What fibre and connectors does this transceiver need?
A: It needs G.652 single-mode fibre terminated with MPO-12 APC connectors. The module has two MPO-12 APC connectors for its parallel optical lanes.

Q: Can it connect to 400G or 100G optics?
A: Yes. It is optically interoperable with 400GBASE-XDR4 optics and with 4 x 100GBASE-FR up to 2km, which allows breakout of the eight 100G lanes.

Q: What host port does it require?
A: It is designed for Arista 800G OSFP ports. It draws up to 16W, so the host port must support the OSFP 800G power class.

Q: How does 2XDR4 differ from the 2PLR4 and 2FR4 variants?
A: The 2XDR4 uses dual MPO-12 APC connectors with a 2km reach over parallel single-mode fibre. The 2PLR4 variant reaches 10km, and the 2FR4 variant uses duplex LC connectors.

Q: What is the maximum reach?
A: The maximum reach is 2km over parallel single-mode fibre at 1310nm.
