Description

The Arista 400G QSFP-DD XDR4 transceiver is a 400GBASE-XDR4 optic for data centre links of up to 2km over parallel single-mode fibre. It suits spine and leaf uplinks and 400G to 4 x 100G FR breakout deployments on supported Arista 400G platforms.

This standard variant uses an MPO-12 APC connector at 1310nm over G.652 single-mode fibre. 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 12W. The optic interoperates with 4 x 100GBASE-FR links, so each 100G lane can terminate on a 100G FR port.

It fits 400G QSFP-DD ports on supported Arista platforms. The related -S variant uses SN optical connectors and the -C variant supports channelised 2x 200G, so confirm the connector type and breakout needs before ordering. The OSFP equivalent is OSFP-400G-XDR4.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What connector does this transceiver use?
A: It uses an MPO-12 APC connector over parallel single-mode fibre. The related QDD-400G-XDR4-S variant uses SN optical connectors instead.

Q: Can it connect to 100G ports?
A: Yes. It interoperates optically with 4 x 100GBASE-FR links up to 2km, so each lane can terminate on a 100G FR port using a suitable breakout arrangement.

Q: How does it differ from the -S and -C variants?
A: This is the standard variant with an MPO-12 APC connector. The -S variant uses SN optical connectors and the -C variant is channelised to support 2x 200G.

Q: What fibre and reach does it support?
A: It supports up to 2km over G.652 parallel single-mode fibre at 1310nm.

Q: What is the power consumption?
A: Maximum power consumption is 12W per module, which should be considered in the port power and cooling budget of the host platform.

Q: Is there an OSFP version?
A: Yes. The OSFP equivalent is OSFP-400G-XDR4, for platforms with OSFP ports instead of QSFP-DD.
