Network Transceiver for 10 km Links

The HPE Aruba JL781A is a 1G SFP LC LX transceiver designed for single-mode fibre connections up to 10 km. It suits network administrators extending campus or metro Ethernet links between switches or routers.

Industrial Temperature Operation

The module supports an industrial temperature range for deployment in harsh environments such as outdoor cabinets or unconditioned wiring closets. This capability reduces the need for additional climate control hardware in demanding installations.

Verify SFP Port and Fibre Type

Confirm the host device accepts standard SFP transceivers and that the link uses LC-terminated single-mode fibre. Ensure the required 10 km reach matches the planned cable run before ordering.

Questions about this item

When will the JL781A transceiver need replacement?

The JL781A is a new component with no moving parts; it runs until optical output degrades or a link budget change demands a different reach.

What limits the JL781A during continuous operation?

The 10 km single-mode reach defines the maximum link distance; signal loss beyond that is the first hard boundary.

How much heat does the JL781A produce when running all day?

As a passive 1 G SFP module it draws minimal power and generates negligible heat inside the switch chassis.
