Four-Channel RCA Fiber Extender

This device converts four line-level unbalanced RCA audio signals into optical fibre for transmission over long distances. It supports both single-mode fibre up to 20 kilometres and multi-mode fibre up to 2 kilometres. The unit handles 16-bit and 24-bit digitally encoded analog audio without software drivers.

Hot-Pluggable SFP Modules Included

Supplied SFP transceivers enable immediate deployment and allow the link type to be changed by swapping modules. The extender operates in point-to-point or daisy-chain topologies and can be used standalone or mounted in an FVC14 chassis. Front-panel LEDs provide instant visual confirmation of signal presence and link status.

20 Kilometre Single-Mode Reach

The maximum transmission distance over single-mode fibre is 20 kilometres, while multi-mode fibre is limited to 2 kilometres. Installations requiring longer single-mode runs or different connector types will need alternative equipment. Buyers needing more than four audio channels or balanced XLR connectivity cannot use this unit.

Questions about this item

Will the SFP modules need replacing after a certain distance or time?

The hot-pluggable SFP modules are included and rated for 20 kilometres on single-mode fibre or 2 kilometres on multi-mode; they require no scheduled replacement under normal operation.

What limits the maximum cable run before signal quality drops?

The extender supports up to 20 kilometres on single-mode fibre and 2 kilometres on multi-mode fibre with no loss in signal quality.

How much heat or noise does the unit produce when running continuously in a rack?

The device is fanless and uses passive cooling, so it generates minimal heat and no audible noise during all-day operation.
