Single Fiber or Multi-Fiber Testing Platform

The RL1 Automated Return Loss Meter has been precisely designed for the most accurate mandrel-free insertion loss and return loss measurements available in the industry. The RL1 can contain up to 4 built-in wavelengths (850, 1300, 1310, 1490, 1550, 1625, 1650nm) with the option of a dual front panel output. Unique to the RL1, the optical meter has been designed with many innovative smart features that increase production efciency and improve overall usage


  • Most accurate RL in its class

  • ​Self-calibration

  • Chassis modular

  • Wireless integrating sphere detector

  • No computer required

  • Ready for production automation

  • Barcode Scan and Test available

  • XN1 ready

  • Cable Assembly Test Software for selecting XN1 profiles, running test sequences, printing labels, and storing data to the XN1 server

  • RL1 can be paired with up to four RD-S Wireless Remote Head power meters.

  • Chassis modular, allowing for quick pairing to equipment part of the XN1 family via USB

  • Integrating sphere can measure loss on MTP/MPO and also duplex LC with one connection

  • RD-S comes standard with SD Slide Detector adapters allowing for the ultimate in ease-of-use

  • RL1 can contain up to 4 built in wavelengths (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm)

  • 1x1 or 1x2 front panel output available

Multi-Fiber Testing with the RL1

Chassis Modular, the RL1 can be connected directly to an additional SX1 switch for multi-fiber testing. The RL1 takes full control of the switch, automating measurements while storing all references and results. If desired, a second SX1 switch can be connected to measure insertion loss, return loss, and verify mapping of multi-fiber connectors or complex assemblies.

XN1 Expandable Network Software

The XN1 expandable Network is designed with reliability and ease of use as top priorities. It is a single server which all XN1 ready devices or software can communicate with to create test plans, store results or print labels.

Pair with an Inspection Scope

Fast End-Face Check Prior to Test

The benchtop CS Inspection Scopes utilize coaxial illumination to provide users with a critical view of fine scratches ideal for post polish, component assembly and QC inspection of fiber connectors. The CS Inspection Scope is available in 200x or 400x magnification. The workstation includes a video microscope, video monitor and universal adapters for 2.5 and 1.25 mm ferrules.
