Santec introduces the RD-SP, a combined integrating sphere and polarity detector
Product Name: Remote-head Integrating Sphere and Polarity Detector
Model: RD-SP-100
SANTEC CORPORATION, a leading manufacturer of advanced optical components, tunable lasers, optical test equipment, and OCT systems, announces the product launch of the RD-SP remote-head integrating sphere and polarity detector. Compatible with Santec’s RLM Return Loss Meter and OSX Optical Switch, the RD-SP lets you test polarity, insertion loss (IL) and return loss (RL) in a single stage for multifiber assemblies such as MPO and duplex LC.

The widely anticipated RD-SP combines the Gen.2 integrating sphere technology already used in the RLM and RD-S with the polarity detector technology used in the RD-P, launched in 2022. This new detector no longer requires any operator intervention between the polarity and IL/RL test stage allowing for insertion loss, return loss, and polarity to be tested in one step. A typical 12 fiber MTP/MPO cable takes only 35 seconds from pressing start to completed results at 2 wavelengths for polarity, IL and RL
Tailored for automated high-volume production testing, Santec's complimentary Cable Assembly software streamlines the process—simply connect the reference cable from the device under test (DUT) to the RD-SP, click start, and let the software do the rest, eliminating operator errors and delivering over double the speed of other premium test solutions.
Revolutionize multifiber assembly testing with the RD-SP remote-head integrating sphere and polarity detector, designed to effortlessly integrate with Santec's RLM Return Loss Meter and OSX Optical Switch for advanced optical testing.

Features:
- Polarity and insertion loss all in one
- Mass production ready: based on ruggedized and proven RD-S and RD-P design
- Efficient: reduces technician interaction and is twice as fast as conventional polarity and IL methods
Fiber Array Units (FAU) have become a necessary tool for coupling light into and out of a photonic integrated circuit. Qualifying these assemblies for loss can be challenging due to the non-standard nature and compactness of the FAU assembly. Santec has released a new application note detailing the equipment requirements and testing methods to obtain repeatable and accurate loss measurements on such assemblies.
