Multi-Fiber Testing Platform

The MBR1 Multi-Channel Backreflection Meter is an instrument developed with extremely stable optics for precise measurement of backreflection, insertion loss, and power. Available with 4, 12, 16, 24, 32, 48 or 72 output channels, the MBR1 is a practical choice for both single fiber and multifiber testing.


  • Stable BR measurements at low values

  • Single Mode and Multi-Mode

  • Available with 4, 12, 16, 24, 32, 48 or 72 output channels

  • IL and BR measurements

  • Up to 4 internal lasers

  • The MBR1 features up to four built-in laser sources at wavelengths of 450, 650, 780, 850, 1060 1300, 1310, 1490, 1550, 1625 or 1650 nm (depending on fiber type)

  • The multimode option of the MBR1 meets IEC 61280-4-1 Encircled Flux standard.


  • The MBR1 is a practical choice for both single fiber and multifiber testing

  • Custom configurations available per request

  • The MBR1 achieves ultra-stable backreflection measurements at very low values with accuracy typically at ±0.4 dB and measurement sensitivity is to –80dB. c

  • Cavity option available for multi-fiber connectors with large fiber counts

  • GMS software to help automate short and long term testing

Cassette Testing with the MBR5

Testing short devices can be dificult and time consuming. By using the MBR1, testing of IL/BR can be completed faster than any other solution while maintaining measurement accuracy. Results can be saved and test sequences can be automated by using the GMS Software.

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.
