Fiber Optic Desktop Insertion Loss& Return Loss Test Machine

Product Details

1. Outlines

Desktop Insertion Return Loss Tester with color screen has stable and reliable performance, which integrates stable light source, high-precision power meter, insertion loss meter and return loss meter into one multifunction instrument. Based on domestic customers’ requirements, R&D team combined advantages of same type instrument within China/overseas and then developed the high-precision tester by several years’s unremitting effort. With high cost effective and state of art characteristics, it can be widely used for OEM device verification, research institutions R&D and construction maintenance in optical fiber/passive devices/optical communication system industries where demand plug loss, return loss and stability measurements



l Advanced OS

Multiple display, easy handling, fast response and stability

l High precision

Stable output power/high detection speed/wide measurement range

l Wavelength synchronous switching

l Light source and power meter achieve wavelength synchronous switching under insertion/return loss mode

l Multiple working modes

Return loss mode/insertion loss mode/power meter/dual-wavelength testing

l Color recognition for test result

Different colors correspond different test results. Pass/Fail is available by just a glance. P

l Easy handling

Return loss/insertion loss are synchronously measured. No buttons switching

l Rich display interfaces

High definition LCD plus multi-level test interfaces bring rich visual experience and easing visual fatigue

l Perfect outward design

Electro-magnetic proofing by metal covering. Durable buttons bring comfortable finger handling experience

l Smart removable interfaces of light source and power meter

Easy to be disassembled to clean optical detector or replace with others adapters(FC/SC/ST/2.5mm general/1.25mm general/MT-RJ) or clean inside APC adapter. Note only need to rotate light source/power meter interface to disassemble it

l Clock display

Time is available to reasonably organize work

l Communication interfaces

The tester can connect to computer and transmit test data to it. Specialized program give Pass/Fail result of jumper. Test data is available for analysis, readout and record.
