Technical content

Coherent’s XPDV21x0R(A) platform exhibits an optimized frequency response in both power and phase. It is ideally suited for OC-768/STM-256 long-haul systems. The on-chip integrated bias network with an optimized RF design ensures an undisturbed frequency response from DC to the 3 dB cut-off frequency and saves costs for internal bias tees. The hermetic module is especially designed for optimal RF performance; therefore, the pulse response reveals virtually no ringing. A further advantage of the waveguide structure is the unbeatable highpower behavior. The photodetector shows a linear response up to an optical input power of 10 dBm, resulting in a high output voltage swing and avoiding the need for electrical amplification. FEATURES APPLICATIONS

  • 50 GHz typical bandwidth with flat response
  • High linearity
  • Excellent pulse behavior
  • Well-matched 50 Ω output
  • Unique on-chip integrated bias network
  • Metro and long-haul transmission
  • Datacenter interconnects
