rBT3250

50G Burst Mode Bit Error Ratio Tester

Semight 50G Burst Mode Bit Error Ratio Tester rBT3250 is specifically designed for testing new burst error code analyzers for optical line terminals (OLTs) in next-generation 25G/50G passive optical network (PON) applications, used to evaluate the performance of 25G or 50G OLT receivers in burst mode.

  • Multirate – Burst rate: 24.8832/25.78125/49.7664/51.5625 Gbps
  • Sudden channel configuration – 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
  • 2 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 rBT3250 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.
