OTDR launch boxes and fibre test accessories

An OTDR suitable for the fibre and measurement task, compatible test cords and, depending on the objective, launch and receive fibres. Wavelength, settings and connector interfaces must match the setup.

It provides a defined length before the first connection of the fibre under test so that this connection can be assessed outside the relevant dead zone. Length depends on the instrument and settings.

Transmission mode and specific fibre specification must match the instrument, wavelength and fibre under test. Also check both connector interfaces.

The connector end-face polish geometry differs. Match connectors, adapters and mating interfaces; the same connector shape does not automatically ensure compatibility. Do not mate UPC and APC directly.

The launch fibre precedes the fibre under test; a receive fibre at the far end enables assessment of the final connection. Required components depend on the test objective and specification.

No. An OTDR analyses events along the route; insertion loss testing assesses the total connection loss. Required methods depend on the result needed.

The length depends on the OTDR, measurement settings and test objective. Confirm these before selection.

According to its product information, the OM3 through-type box MT09949 shown is also intended for use as a receive fibre. Suitability of other models must be checked separately.

This listing currently contains launch boxes. These are test setup accessories, not measuring instruments.
