Description

This 100GBASE-SR4 QSFP28 optical transceiver is built for short-reach 100GbE links inside the data centre. It runs over parallel multimode fibre at 850nm using an MPO-12 UPC connector, and is hot-swappable so a link can be added or replaced without taking the switch offline.

Reach is up to 70m over OM3 and up to 100m over OM4 multimode fibre, both with a 50.0 um core. Per-lane transmit power is -8.4 to +2.4 dBm and receive power is -10.3 to +2.4 dBm. Maximum power consumption is 3.5W, drawn from the host switch port. The module measures 13.5 x 18.4 x 72.4 mm and operates at a case temperature of 0 to 70 C.

It is intended for Arista switches with 100G QSFP28 ports and interoperates with other 100GBASE-SR4 optics over MPO-12 parallel multimode fibre. It complies with IEEE 802.3 and the QSFP28 SFF-8449 and SFF-8636 specifications. Where the host port supports it, 4x25G breakout cabling is also possible.

FAQs

Q: What fibre do I need for this transceiver?
A: It uses parallel multimode fibre terminated with MPO-12 UPC connectors. OM3 fibre reaches up to 70m and OM4 fibre reaches up to 100m.

Q: Which switches does it work with?
A: It suits Arista switches with 100G QSFP28 ports. It also interoperates with other 100GBASE-SR4 optics over MPO-12 parallel multimode fibre.

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

Q: Can it be used for 4x25G breakout?
A: The manufacturer datasheet describes 4x25G breakout cabling with this optic type. Confirm that your switch port supports breakout mode before ordering.

Q: Is it hot-swappable?
A: Yes. The module can be inserted or removed while the switch is powered, so you can add or replace links without a maintenance outage.
