OTC2500 OTDR Module Highlights

Smaller than A5-size for Optical Line Monitoring Systems

Space is a vital limitation which cannot be neglected in an optical line monitoring system designing. Also, functions, performance, and cost lead customer to prefer smaller OTDR module. OTC2500 Card OTDR module (90x70x12.5mm) is smaller than A5 size (200x130x25mm), absolutely can satisfy the monitoring system requirement for space compression.

High Performance OTDR Module

Event dead zone for OTC2500 Card OTDR is less than 0.8m, and attenuation dead zone is less than 3.5m. The maximum dynamic range is 43dB. The minimum sampling resolution is 8cm and the sampling points up to 256,000.

Fast Data Transmission over Ethernet Interface

Optical line is monitored by various reasons. Mainly for assessing long-term performance changes of the optical lines such as loss, the system will check the fibre every several hours by using OTDR regularly. For other applications, such as network fault by road repairs, installing post or guardrail, breaks caused by landslips, earthquakes, etc., the system checks the fibre immediately using an OTDR to find the fibre break.

OTC2500 OTDR module can perform trace sweep by 5 second interval smoothly average. The 10/100M Base-T Ethernet interface transmits waveform data to controller by high speeds, which makes fibre monitoring much easier.

Fast and Precision Operation from Controller

OTC2500 OTDR Module has a 10/100M Base-T compatible Ethernet interface for controlling over an Ethernet network. (The IP address is set using UART(3.3VTTL).)

A comprehensive set of commands is built-in, including commands for setting measurements conditions, transferring measured data to the controller, along with a full range of file formats, making it easy to match setting with monitored fibre.

A friendly user interface OTDR software developed by OPWILL, it can install in the PC to control OTC2500 OTDR module through the controller.
