Optical Time Domain Reflectometer

The GW4000 optical time domain reflectometer is a portable OTDR designed for FTTx applications. It is mainly utilized to measure fiber length, overall attenuation, splice loss, mated-connector loss as well as other physical parameters, and it can also locate events and faults.

1. This single mode OTDR weighs only about 1kg, so it is very easy to carry. However, due to the overmolding process, it is very robust, and the anti-reflective LCD screen is able to provide clear images even in field environment.
2. Our optical time domain reflectometer carries out real-time measurement either automatically or manually, and it also offers rapid data analysis for a single curve as well as contrastive analysis among several curves.
3. The event dead zone is only 1.6m, and VFL function is provided as well. On the other hand, the light output tip is replaceable, and it is very convenient to clean its end faces.
4. With a USB interface, this optic fiber tester realizes both automatic and manual data storage of more than 1000 test results, and the standard format is Bellcore GR-196.
5. Thanks to the large-capacity Li-ion battery, the optical time domain reflectometer is able to work for 10 hours, making it an ideal choice for outside plant applications. For the convenience of users, remaining battery capacity is revealed on the LCD, and low battery notification is also supplied.
6. Our optical time domain reflectometer could be shut down automatically at the preset time.
