Description

This 100GBASE-PLRL4 QSFP28 transceiver is built for data centre and campus links of up to 2 km over parallel single-mode fibre. It suits 100G-to-4x25G breakout designs and 40G-mode connections where PSM4 reach of 500m is too short but a 10km PLR4 optic is more than the link needs.

It connects through an MPO-12 APC interface over G.652 single-mode fibre at a nominal wavelength of 1310 nm. The module operates as either 100G or 40G (dual rate). 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 is designed for Arista switches with QSFP100 ports running EOS 4.27.1.1 or later. It interoperates with 4x25G LR-type optics such as SFP-25G-LR through an MPO breakout, and with 100GBASE-PSM4 modules at up to 500m. In 40G mode it interoperates with 40GBASE-PLRL4 at up to 1 km over parallel single-mode fibre.

FAQs

Q: Does it support 4x25G breakout?
A: Yes. The 1310 nm 4x25G lanes on the MPO-12 APC connector can be broken out to 4x25G, and it interoperates with 4x25G LR-type optics such as SFP-25G-LR.

Q: What fibre and connector does it use?
A: It uses parallel single-mode fibre (G.652) terminated with an MPO-12 APC connector. APC polish is required, so match the patch cabling accordingly.

Q: Which switches and software does it need?
A: It is designed for Arista switches with QSFP100 ports running EOS 4.27.1.1 or later. Check the Arista Transceiver Guide for per-platform support.

Q: How does it differ from PSM4 and PLR4 optics?
A: PLRL4 reaches up to 2 km, sitting between PSM4 at 500m and PLR4 at 10km. It also interoperates with 100GBASE-PSM4 modules at up to 500m.

Q: Can it run at 40G?
A: Yes. It is a 100G/40G dual-rate module. In 40G mode it interoperates with 40GBASE-PLRL4 at up to 1 km over parallel single-mode fibre.
