1 Overview
1.1 Product Overview
ZW-3327 IL&RL Test Station is a combination of years production and testing
experience of its own optical passive components and optical communication
instrumentation, fully drawing on the advantages of instrumentation at home and
abroad, elaborate development of a precision optical detection instrument. It is widely
used in insertion loss and return loss testing for fiber optic cables, Passive optical
device and Fiber-optic communication systems, it is the basic test instrument for
manufacturers, scientific research institutions and operators for production testing,
research and development, and Engineering Construction and maintenance.
1.2 Features
1) Built-in High Stability Optical Light Source;
2) Multi-test mode, support dual-wavelength IL RL simultaneous test;
3) The upper computer and lower computer threshold can be set;
4) Support Multiple Fiber interface conversion;
5) Large color screen display
6) Support Multiple Communication Interfaces;
7) The insertion loss of multimode patch cord can be detected by adding 850
wavelength
8) Light Path built-in VFL, easy to find the other end of the patch cord, enhance the
test speed;
