Multimode Two-Way Loss & Length Test Set
DESCRIPTION
A Two-Way Optical Loss Test set (OLTS) that’s perfect for medium to ultra high fiber count loss & length testing applications on multimode fiber at 850 / 1330nm. A pair of these compact instruments set new standards of productivity, accuracy and ease of use. The 650 nm VFL VisiTester feature mixes a VFL in with the test signal during Autotest. It operates as a stand-alone VFL, or gives positive visual identification of a fiber to be connected during loss testing.
Each fiber needs just one test hook-up and one key press for a complete bidirectional loss and length test, eliminating administration, training and test errors. Testing is accurate and can take only 5 seconds, direct onto flexible standards-compliant Tier 1 certification reports.
A pair of instruments both display length & bi-directional loss, in real time, with no need to specify master/slave instruments. A single instrument can also be used as a stand-alone light source & power meter, VFL, or tone generator / detector.

Common Questions About the Multimode Two-Way Loss & Length Test Set
What type of fiber is this test set designed for?
It is purpose-built for multimode fiber testing at 850 and 1300 nm, making it ideal for medium to ultra high fiber count environments.
How does two-way testing improve efficiency?
Each fiber requires only one connection and one button press to complete bidirectional loss and length testing, cutting test time and reducing setup and training errors.
What is the benefit of the built-in VFL?
The integrated 650 nm VisiTester functions as a standalone VFL and provides positive visual identification of fibers during loss testing.
Can a single unit be used on its own?
Yes, one instrument can operate independently as a light source, power meter, VFL, or tone generator and detector.
