Aruba 100G SR1.2 QSFP28 transceiver

This Aruba QSFP28 transceiver delivers 100 Gigabit Ethernet connectivity for data networking and optical networks. It uses a plug-in module form factor with a single LC connector for multi-mode fiber links. The unit is built for high bandwidth performance and reliable connectivity between servers and network components.

100 metre reach on multi-mode fiber

The module supports a maximum distance of 0.10 km over multi-mode fiber using 100GBase-SR1.2 signalling. Multi-mode cable with its thicker diameter carries multiple wavelengths to sustain the 100 Gbit/s rate. Beyond the rated reach the link will not operate reliably.

Single LC 100GBase-SR1.2 interface

The transceiver presents one LC port running 100GBase-SR1.2, so it only fits links designed for that exact standard and distance. Ports expecting a different SR variant or a longer reach will not interoperate with this module.

Questions about this item

Will this S4B44A module link with my existing OM4 multi-mode patch cables at 100 Gbit/s?

Yes, the transceiver uses a duplex LC connector and is rated for 100 Gbit/s over multi-mode fibre up to 100 m, matching standard OM4 patch cords.

How can I verify the link is running at the advertised 100 Gbit/s after I install the module?

Check the switch port status or monitoring software; it should report a 100GBase-SR1.2 link at 100 Gbit/s with the module recognised as an S4B44A.

Does the S4B44A ship with any cables or cleaning tools, or must I order them separately?

Only the transceiver module is included; LC duplex patch cables and fibre cleaning supplies must be purchased separately.
