Compatible 100G QSFP28 Transceiver

The AddOn JL309A-AO is a 100GBase-SR4 QSFP28 transceiver module built for 100 Gigabit Ethernet links. It operates at 850 nm over multimode fibre with an MPO connector and reaches 100 metres. Digital optical monitoring is included for real-time link diagnostics. The unit weighs .4 pounds and carries TAA compliance for regulated procurements.

For 100G MMF Links Up To 100m

This module suits network engineers deploying 100GBase-SR4 connections between switches or routers within a single data centre row or campus building. It matches the HP JL309A form factor and wavelength exactly. Buyers who need single-mode reach, longer distances, or a different connector type such as LC should look at other form factors.

850nm Multimode 100m Reach

The decisive specification is the 850 nm multimode interface rated for 100 metres over OM4 fibre. This distance and wavelength define the physical link budget and fibre plant compatibility. If the installation requires a longer span or single-mode cabling, this transceiver will not meet the requirement.

Questions about this item

Does the AddOn JL309A-AO transceiver ship with any cables or patch cords?

The transceiver is supplied as a standalone module; compatible MPO multi-mode fibre patch cords must be purchased separately.

How do I confirm this 100GBase-SR4 module matches the port I need to populate?

Verify the host equipment accepts a QSFP28 form factor and supports 100GBase-SR4 over multi-mode fibre at 850 nm.

What link distance can I expect when the module is installed in a live switch?

The transceiver is rated for 100 metres over OM4 multi-mode fibre when used with a compliant MPO connection.
