Transponders TQ-10P and TO-10P

Cost-effective solution for transferring client streams from 155 Mbit/s to 10 Gbit/s without FEC

  • Transmission of client signals: STM-4/16/64, 1/10GE, OTU1, 2/4GFC
  • Linear and client interfaces SFP/SFP +
  • Universal multi-service and inexpensive solution
  • 4 or 8 transponders on one board
  • Ultra-low signal delay

Universal transponder without FEC enables you to build flexible and cost-effective CWDM/DWDM systems. 3R-regeneration of the signal is performed for each channel (reamplification, reshaping, retiming). Tunable SFP+ or “color” SFP/SFP+ with a fixed wavelength can be used on each line port. The use of standard SFP+ connectors significantly increases the cost-efficiency of the solution. A wide range of client interfaces with speeds from 155 Mbit/s to 10 Gbit/s enables smooth upgrade of client equipment without a need to change the transponder. The device supports both STM and 1GE/10GE ports that makes it possible to arrange SDH-rings and IP-networks.
