Description

This 100GBASE-XSR4 QSFP28 transceiver is built for short-reach 100G links over parallel multimode fibre inside the data centre. It suits leaf-spine and aggregation links where a standard SR4 optic runs out of reach, and it plugs into 100G QSFP100/QSFP28 ports on Arista switches.

It transmits at 850nm using four 25G lanes over a parallel multimode fibre pair with an MPO-12 UPC connector. Reach is 150m over OM3 and 300m over OM4, which is more than standard 100GBASE-SR4 at 70m on OM3 and 100m on OM4. Maximum power consumption is 3.5W, and the module operates at a case temperature of 0 to 70 C.

It needs parallel OM3 or OM4 multimode fibre terminated with MPO-12 UPC connectors. Optical interoperability with 100GbE CFP, CFP2 and CPAK optics is listed in the Arista datasheet.

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

FAQs

Q: What fibre does this transceiver need?
A: It needs parallel multimode fibre, OM3 or OM4, terminated with MPO-12 UPC connectors. Reach is 150m over OM3 and 300m over OM4.

Q: How does XSR4 differ from standard SR4?
A: XSR4 extends reach over the same parallel multimode fibre. It reaches 150m on OM3 and 300m on OM4, compared with 70m and 100m for 100GBASE-SR4.

Q: What ports does it fit?
A: It is a QSFP28 form factor module for 100G QSFP100/QSFP28 ports on Arista switches.

Q: How much power does it use?
A: Maximum power consumption is 3.5W, drawn from the host switch port, so no separate power supply is needed.

Q: Will it interoperate with other 100G optics?
A: The Arista datasheet lists optical interoperability with 100GbE CFP, CFP2 and CPAK optics.
