2-Channel 850 nm Multimode Video Receiver
The IFS VR1001 is a 2-channel video receiver designed for multimode fibre links operating at 850 nm. It accepts optical signals through ST connectors and converts them to a 1 volt peak-to-peak video output at 75 ohms. The unit is powered via a terminal block with screw clamps and provides a bandwidth of 5 Hz to 10 MHz for baseband video transport.
Installers Extending Analogue Video Over Fibre
This receiver suits installers who need to extend composite video signals over existing multimode fibre infrastructure using ST terminations. It is not intended for digital video formats such as SDI or HDMI, nor for single-mode fibre runs. Buyers requiring more than two channels or a different connector type should consider alternative models.
Receiver Sensitivity -30 dBm
The optical receiver sensitivity is rated at -30 dBm (1 µW), which determines the maximum allowable link loss for a reliable video signal. System designers must calculate the total attenuation of the fibre plant, connectors and splices to ensure the received power stays above this threshold. The transmitter output of 25 µW sets the launch power for the corresponding VR1001 transmitter.

Questions about this item
How is the IFS VR1001 mounted and which wiring step is often missed?
The receiver mounts in a rack or panel and draws power from a terminal block with screw clamps; the step most installers miss is tightening each clamp firmly so the connection stays secure under vibration.
What part will need replacement first and how often?
The 850 nm multimode optical receiver degrades slowly; plan to verify the -30 dBm sensitivity threshold annually and swap the module if received power drops below that level.
What is the first limit reached during continuous operation?
The 10 MHz video bandwidth ceiling is the first hard limit; signals with frequency content above that roll off, so the link cannot pass full-motion detail beyond 10 MHz regardless of fiber length.
