Description

This 100G QSFP28 bidirectional (BiDi) transceiver from the Arista 100G QSFP optics range carries 100G over duplex multi-mode fibre with LC connectors. It suits data-centre links that need to run 100G over existing duplex OM3 or OM4 cabling, including migration from duplex 10G and 40G links and breakout from 400G-BIDI ports.

The BiDi design sends 50G in each direction on each fibre, giving 100G in aggregate over the two LC ports, so no parallel MPO fibre infrastructure is needed. Reach is up to 70m over OM3 and up to 100m over OM4 multi-mode fibre, using 855 nm and 908 nm wavelengths on 50 um core fibre.

It is supported on Arista QSFP 100G ports and interoperates with Arista OSFP-400G-SRBD and QDD-400G-SRBD 400G-BIDI optics when breaking out to 4x100G. Both ends of a link must use the same transceiver type, as it does not interoperate with QSFP-100G-SWDM4.

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

FAQs

Q: Which fibre does this transceiver need?
A: It runs over duplex OM3 or OM4 multi-mode fibre with LC connectors. Reach is up to 70m on OM3 and up to 100m on OM4.

Q: Does it work with Arista 400G-BIDI ports?
A: Yes. It interoperates with Arista OSFP-400G-SRBD and QDD-400G-SRBD optics when breaking out a 400G port to 4x100G.

Q: Can I link it to a QSFP-100G-SWDM4 transceiver?
A: No. It does not interoperate with QSFP-100G-SWDM4. Both ends of a link must use the same transceiver type.

Q: Which switch ports is it supported on?
A: It is supported on Arista QSFP 100G ports and is powered by the host switch QSFP28 port.
