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.
