FTS2 Series Fiber Optic Talk Sets

Fiber Optic Talk Sets are an inexpensive solution to meet your communication needs when testing multimode or single-mode fiber optic cables. Designed for voice communication over spare fibers, NOYES FTS units from AFL provide full duplex, hands-free operation. Ease of use and compact size allow the operators to focus on the task at hand, rather than operating the talk set.

FTS2 Series Fiber Optic Talk Sets


  • 1310 nm operation lessens bend loss
  • 45 dB dynamic range communicates up to 128 km (80 miles) over SM fiber
  • 20 dB dynamic range with (OM1 – OM4) multimode fiber


  • 1550 nm operation for maximum distance over single-mode fiber
  • 45 dB dynamic range communicates up to 225 km (140 miles) over SM fiber
  • 20 dB dynamic range with (OM1 – OM4) multimode fiber
FTS 2 multiparty communication feature allows for connection of two NOYES FTS2 talk sets at a common site to extend the range or to include three or more persons in the conversation.

FTS-20C Clip-on Coupler

Available FTS2 accessory provides connectivity in the middle of  single-mode fiber spans or at bare fiber ends.  The FTS-20C can also be used in conjunction with a laser source or a tone detector to inject or detect 2 kHz test tones for fiber identification. It works at 1310, 1550, or 1625 nm. Coupling efficiency is approximately 18 dB.

With the wide coverage of cell phones who needs a fiber optic talk set?  

  • Fiber technicians who want to be assured they can communicate while testing fiber spans regardless of location.  Fiber distribution hubs can be located in basements or enclosed areas with limited or no cell phone coverage.  Utilizing one unused fiber for talk set communication ensures crystal clear communication regardless of location.
  • Military and other secure locations may prohibit cell phone usage – especially today where most cell phones include a high resolution camera.  This is not a barrier to technicians equipped with a fiber optic talk set.
