FTTH CPE gateways
Neutral Fiber Termination Unit (FTU)
Key features
- Combined FTU & Media Converter
- Maximum flexibility and scaleability
- Auto sense 100/1000 MBits/s
- Attractive installation cost (CAPEX)
- Minimal maintenance overhead (OPEX)
Built upon the strong DKTCOMEGA CPE/gateway product line, this is a new series of Fiber Termination Units / Wall Outlet that offers operators an easy FTTH Termination demarcation point in euro connector size. The series include a passive part to be installed during fiber termination as well as several active parts to be installed by the end customer.

Product presentation
The 79700 Passive Fiber Termination Unit (FTU) consists of two pieces, one part for
fiber management and one protection part curved cover.
Usage models:
Active Optical Outlet
The bottom part is used for fiber management, the protection cover is removed, and an
active part (79701 - 703) can be clicked on top of the bottom part.
Passive Optical Outlet
If 3rd party active equipment is used, such as switches and routers, then the FTU can
be used as Passive Optical Outlet. The protection part of the device can be used
to secure patch cables for external connectivity, whereas the bottom part
is used for fiber management.
