Description

The QSFP-40G-PLR4 is a 40G QSFP+ optical transceiver that runs four parallel 10G lanes over parallel single-mode fibre, reaching up to 10km. It uses an MPO-12 APC (MTP-12) connector and operates at 1310nm over G.652 SMF, making it suited to long-reach 40G links and 4x10G breakout deployments in data centre and campus networks.

This 40GBASE-PLR4 optic interoperates with 4x10G LR optics up to 10km and with LRL optics up to 1km. It forms part of Arista's 40G QSFP+ optics portfolio, with a maximum power consumption of 3.5W.

FAQs

Q: What fibre and connector does the QSFP-40G-PLR4 use?
A: It uses parallel single-mode fibre (SMF G.652) terminated with an MPO-12 APC (MTP-12) connector, operating at 1310nm.

Q: What is the maximum reach of this transceiver?
A: The QSFP-40G-PLR4 supports links of up to 10km over parallel single-mode fibre.

Q: Can it interoperate with other optics?
A: Yes. It interoperates with 4x10G LR optics up to 10km and with LRL optics up to 1km.

Q: Does it support breakout to 10G links?
A: Yes. Its four parallel 10G lanes support breakout to 10G links over parallel SMF.

Q: What is the power consumption?
A: Maximum power consumption is 3.5W.

Q: Is this the same as a duplex LC 40G LR4 optic?
A: No. The PLR4 uses four parallel fibre lanes over an MPO-12 (MTP-12) connector rather than a duplex LC connector, so it needs parallel SMF cabling.
