Test and Measurement Tool

The Tripp Lite N844-LOOP-12F is a fibre optic loopback tester designed for network engineers and technicians performing signal verification in MTP/MPO environments. It supports test and measurement procedures by returning the transmitted signal directly back to the source equipment. The aqua housing identifies the multimode OM3 rating at a glance.

Multimode OM3 Pin Configuration

The single specification that determines compatibility is the pin mapping: 1-12, 2-11, 3-10, 4-9, 5-8, 6-7 across twelve fibres. This tester is built for 50/125 µm multimode fibre rated to OM3 standards. It will not function in single-mode links or in systems requiring a different fibre count or polarity scheme.

Passive Operation

As a passive loopback device it draws no power and generates no heat or noise during normal use. The push-pull tab allows quick insertion and removal from dense patch panels without tools. A protective dust cover shields the female MTP/MPO connector from contamination during storage. Buyers needing active signal regeneration or protocol analysis require a different class of instrument.

Questions about this item

What does the 12-fibre pin configuration actually do in a live link?

The pin map pairs fibres 1–12, 2–11, 3–10, 4–9, 5–8 and 6–7 so each transmit path loops straight back to its matching receive path for end-to-end verification.

Which MTP/MPO standard does the tester follow and what bandwidth does that support?

It is built to the OM3 50/125 µm multimode specification, which is rated for 10 Gb/s and higher speeds over short-reach links.

Will the 4-inch body and push-pull tab fit inside a high-density patch panel?

The 4-inch overall length and integrated push-pull tab are designed for tight panel spacing, allowing quick insertion and removal without tools.
