Mr Henry Thai
    Kocent Optec Limited is our long-term partner. In 8 years of co-operation times we together win many projects. Their fast connector and FTTH drop cable quality are best. Their products are cover my country now.
    Mr Pablo
    I was surprised when i made first order with Kocent Optec Limited in 2014. One container 40GP of GYXTW cable and one container 20GP for fast connector, patch cord and adapter. They finished this order in 2 weeks only. Now we also purchase many type of FDB box and Splice Closure Box from them. Hope we will be stronger and stronger in telecom field.

Product Description

IL RL Fiber Optic Polishing Equipment Optical Return Loss Test Sets




-Insertion Loss/Return Loss Test Station is a high performance loss test station that is designed specially for Optical Passive Components production Test and Lab Test. It combines three different working modes as a return loss meter, optical power and loss meter and a stable laser source in one test station.



- Outstanding measurement accuracy and repeatability:

With built-in optical isolators in the lasers, with the most advanced microelectronics technology and high quality optical devices, and incorporated well-designed built-in software, to ensure the test station has a high stable output power, quick testing speed and wide measurement range.

- Automatic wavelength setting with synchronization:

In return loss test model, the optical laser source and optical power meter are at the same measurement wavelength simultaneously. In optical power meter model, measurement wavelength can be set separately."

- Multiple working modes:

Three working modes in one test station: Return loss test, optical power and loss test and stable laser source.

- Easy Operation:

NO button-press operation needed during the measurement of return loss test and insertion loss test. Two LCD window displays design, the return loss value and insertion loss value are displayed on LCD separately to enable the testing results can be seen or read clear in a glance. Operation of “Zero setting” and “Ref setting” be stored in test station automatically, even if the power supply is cut off suddenly and to power on again, normally needn’t recalibration."

- Human Engineering Design:

Comfortable appearance outline, using high quality metal case, to avoid electrical interference caused by production conditions. Attractive and durable Press-button with a perfect handle sense. Equipment holder can be adjustable to satisfy the various applications, meet the Human Engineering requirements. 

- Dust proof and active Optical Interfaces, easy removal for clean and replacement

Active interface be used in both laser source and power meter, easy to remove to clean Optical interface adaptors and photo detector or replace other types adaptors, such as FC/SC/ST/2.5mm universal/1.25mm universal/MT-RJ etc. so that to be used in various types patch cords.
