Description

This Arista 100GBASE-BIDI QSFP transceiver carries 100G Ethernet over a single duplex LC multi-mode fibre pair. It is built for data centre switch-to-switch links where existing duplex OM3 or OM4 cabling is already in place, and for 100G links into 400G-SRBD breakout ports.

It uses two wavelengths, 855 nm and 908 nm, to send traffic in both directions over one fibre pair. Reach is up to 70m on OM3 and 100m on OM4 multi-mode fibre with a 50.0 um core. Transmit power is -6 to +4 dBm per lane and receive power is -7.9 to +4 dBm per lane. This is the 100GBASE-BIDI (100G-SRBD) variant with a duplex LC connector.

It is optically interoperable with the 4x 100GBASE-BIDI breakout mode of Arista OSFP-400G-SRBD and QDD-400G-SRBD modules. It does not interoperate with 100GBASE-SWDM4 optics, which use a different wavelength scheme.

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

FAQs

Q: What 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 100m on OM4.

Q: Can it link to 400G-SRBD ports?
A: Yes. It is optically interoperable with the 4x 100GBASE-BIDI breakout mode of Arista OSFP-400G-SRBD and QDD-400G-SRBD modules.

Q: Will it work with 100GBASE-SWDM4 optics?
A: No. QSFP-100G-SWDM4 uses a different wavelength scheme, so the two types cannot be linked directly.

Q: How does it differ from other 100G short-reach optics?
A: This is the 100GBASE-BIDI variant that uses 855 nm and 908 nm over a duplex LC fibre pair, with reach of 70m on OM3 and 100m on OM4.

Q: Where can I check switch platform support?
A: Arista's Transceiver and Cable Guide lists the supported switch platforms for the QSFP-100G-SRBD.
