Burst Mode Bit Error Ratio Tester
rBT2250
25G Burst Mode Bit Error Ratio Tester
Nexustest rBT2250 is a Burst Mode Bit Error Ratio Tester to evaluate 10G/25G/50G OLT (Optical Line Terminal) receiver performance in burst mode. rBT2250 provides 2 independent pattern generator/ error detector channels, and provide laser enable/ receiver reset/ RSSI trigger signals and SD signal detect function. With built-in burst clock data recovery, clock would be recovered from the burst data every time. It is a must in long fiber testing. The high integration multi-channel design of rBT2250 make it the best choice for burst bit error ratio analysis.
Highlights
  • Multi-rate
    Burst Rate:9.953/ 10.3125/12.4416/24.8832/ 25.78125 Gbps
  • Downlink continuous error bits testing channel
    Optional 1 channel with NRZ up to 25Gbps or 2 channels with NRZ/PAM4 up to 50Gbps
  • Control signal matching
    Provides 2 synchronous ONU laser enable control signals or 2 synchronous reset control signals
