Burst Error Ratio Tester
rBT3250
50G Burst Mode Bit Error Ratio Tester
Semight Instruments 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: 24.8832/25.78125/49.7664/51.5625 GbpsSudden channel configuration
Integrated 2 independent high-speed burst data channels,Support LOS measurement
Separate LOS monitoring/SD monitoring/LOS judgment for each channelBuilt-in clock recovery
It can work in the real long fiber environment to avoid the influence of long fiber on time delay and jitter2 synchronous ONU laser enable control channels
The control level is LVTTL3.3V without the need for external level conversionSupports two dual reset control channels
The reset position and reset width can be adjustedFeatures 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,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.
