The Optical Wavelength Labs HO-850 HOOTS is a High Output Optical Talk Set configured to 850nm. The transmitter in the HO-850 HOOTS also serves as a calibrated -20.0 dBm multimode light source. It uses LED technology to convert your voice into optical signals for full-duplex voice communications over a pair of multimode fibers. The HOOTS is a reliable alternative to wireless communications systems, and is very simple to use. Communications over optical fibers with the HOOTS offers both security and electromagnetic immunity.

The HOOTS has been designed to be an economical alternative to walkie-talkies. Optionally, it can be embedded as a permanent part of a fiber network installation. Use it during the installation for end-to-end voice communications. After installation, leave it attached to a pair of unused fibers in the patch panel. This way, the HOOTS can be used by communications personnel any time operations or management functions need to be performed in the fiber cable closet.

The HOOTS comes standard with two talk set units (one for both ends of the fiber) in a hard-shell carrying case, and each unit comes with a headset, headset adapter, protective rubber boot, lanyard, 9-volt battery, and a CD-ROM based operations guide.
