Description

The QSFP-100G-PLRL4 is a 100GBASE-PLRL4 QSFP100 optical transceiver from Arista's 100G optics range. It is built for data centre links of up to 2 km over parallel single-mode fibre, and for operators who need 100G-to-4x25G breakout or a 40G/100G dual-rate migration path.

The module operates at 1310 nm over SMF G.652 fibre and terminates in an MPO-12 APC connector. Reach is up to 2 km, sitting between the 500m QSFP-100G-PSM4 and the 10km QSFP-100G-PLR4. Transmit power is -5.5 to +1.5 dBm per lane and receive power is -12.6 to +2.0 dBm per lane. Maximum power consumption is 3.5 W, drawn from the host switch QSFP port. It runs at 100G or 40G, and breaks out to 4x25G links that interoperate with 25GBASE-LR optics up to 2 km, as well as 4x10G breakouts.

It fits QSFP100 ports on Arista switches, with supported platforms and minimum EOS versions listed in the Arista Transceivers and Cables Guide. For breakout deployments, use MPO-to-4xLC single-mode breakout cabling. It is also optically interoperable with the 100GBASE-PLR4 module over shorter distances.

FAQs

Q: How does this differ from the QSFP-100G-PLR4 and QSFP-100G-PSM4?
A: All three use parallel single-mode fibre with an MPO-12 connector. The PLRL4 reaches 2 km, the PLR4 reaches 10 km and the PSM4 reaches 500m.

Q: Can it break out to 25G links?
A: Yes. It supports 4x25G breakout to 25GBASE-LR optics up to 2 km, and 4x10G breakouts. The same FEC mode must be used on both ends for 4x25G breakout links to come up.

Q: What fibre and cabling does it need?
A: It uses parallel single-mode fibre (SMF G.652) with an MPO-12 APC connector. For 4x25G breakout, use MPO-to-4xLC single-mode breakout cabling.

Q: Which ports and switches does it fit?
A: It fits QSFP100 ports on Arista switches. Supported platforms and minimum EOS versions are listed in the Arista Transceivers and Cables Guide.

Q: How much power does it draw?
A: Maximum power consumption is 3.5 W, supplied by the host switch QSFP port.
