50G Burst Mode Bit Error Ratio Tester rBT3250-Semight Instruments

Features

Multirate
Burst rate: 24.8832/25.78125/49.7664/51.5625 Gbps
The burst channel is fully configured
Integrated 2 independent high-speed burst data channels,
Support 2 burst timing configurable code pattern generator channels and 2 burst error test channels
Support LOS measurement
Separate LOS monitoring/SD monitoring/LOS judgment for each channel
Built-in clock recovery
It can work in the real long fiber environment to avoid the influence of long fiber on time delay and jitter
Two synchronous ONU laser enable control channels
The control level is LVTTL3.3V without the need for external level conversion
Supports two dual reset control channels
The reset position and reset width can be adjusted

Features and Benefits

Support Combo PON for burst testing,
Dual reset signals, adjustable reset position, Combo pon requires 2 reset signals;
Dual package testing
Each data packet has different attenuation, there is a phase jump between different data packets, and there are long connections of "1" and "0" in the data packets,
Need to simulate the generation of the worst 2 ONU signals;
Built-in clock recovery, support for long fiber testing
The built-in clock recovery allows rBT2250 to operate in a real long fiber working environment, which is basically impossible to achieve in other commonly used solutions in the industry, because those systems do not support clock recovery and cannot adapt to the impact of long fibers on latency and jitter.
