Description

This 40GBASE-PLRL4 QSFP+ transceiver is built for data centre links of up to 1km over parallel single-mode fibre. It suits operators who want to run 40G on single-mode cabling, or who are stepping from 10G towards 40G and want to keep their fibre plant and port options flexible.

The module uses four parallel 1310nm lanes over a single MPO-12 APC (MTP-12) connector on G.652 single-mode fibre. Transmit power is -8.2 to +0.5 dBm per lane and receive power is -12.5 to +0.5 dBm per lane. Maximum power consumption is 3.5W, drawn from the host switch port, and the module is rated for an operating case temperature of 0 to 70 C. The QSFP+ body measures 13.5 x 18.4 x 72.4 mm.

It is optically interoperable with 4x10G LR/LRL optics up to 1km, which makes it practical for breakout links and gradual 10G-to-40G migration. It installs in Arista QSFP+ ports, and the sibling QSFP-40G-PLR4 (10km) uses the same MPO-12 APC connector.

FAQs

Q: What fibre and connector does this transceiver use?
A: It uses parallel G.652 single-mode fibre with an MPO-12 APC (MTP-12) connector, operating at 1310nm.

Q: Can it link to 4x10G LR or LRL optics?
A: Yes. It is optically interoperable with 4x10G LR/LRL optics up to 1km over parallel single-mode fibre, which suits breakout and migration designs.

Q: How does it differ from QSFP-40G-PLR4?
A: Both use the same MPO-12 APC connector over parallel single-mode fibre. This PLRL4 module reaches up to 1km, while the QSFP-40G-PLR4 reaches 10km.

Q: How much power does it draw?
A: Maximum power consumption is 3.5W, supplied by the host switch port. No separate power supply is needed.

Q: Which switches does it work with?
A: It installs in Arista QSFP+ ports. Check Arista's transceiver compatibility matrix for the supported switch platforms and EOS versions.
