Fiber Delay Spools


  • Our fiber spools are used to create delays from tens of nanoseconds up to hundreds of microseconds
  • Optional integrated DCF (Dispersion Control Fiber) if required
  • Our engineers can assist you in spec’ing the appropriate delay line and RFoF transceiver in designing a delay line solution
  • Pass through connector option to eliminate the need for patch cables and reduce optical loss
  • Delay accuracy of <0.1% or better
  • Custom connectors: FC, SC, LC, ST and APC/UPC type
  • 1 km of single mode fiber provides approximately 5 uS delay

Optical Splitters

  • We offer passive and active splitters
  • 1:2, 1:3, 1:4 passive filters are used when the optical signal has to be split several ways to connect multiple Rx units to one Tx unit
  • Active splitters are needed to compensate the splitter loss as well as the loss that may stem from existing patch panels
  • Active filters may also be used when the RF input power is low and the fiber length is long
