Burst Mode Bit Error Ratio Tester
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.
Features
Multirate
Burst rate: 24.8832/25.78125Downlink Continuous Error Bits Testing Channel
2 channels with NRZ/PAM4 up to 50GbpsControl Signal Matching
Provides 2 synchronous ONU laser enable control signalsRich Trigger Signal
Supports 1 RSSI Trigger signalHigh Efficiency
Quick configuration download and fast hardware response speedFully Match ATE Application
With powerful and flexible database management capabilitiesFunctions and Advantages
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.Built-in Clock Recovery, Supports 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.
