What is a Fiber Distribution Cabinet?

Fiber Distribution Cabinets (also known as FTTH cabinets)  are devices for connecting feeder cables and distribution cables, to protect optical fiber splicing points, and distribute and schedule optical fiber routings.

In North America, it is called a fiber distribution hub (FDH), while it is called a street cabinet in Europe.

And in the Middle East, it has another name-optical distribution cabinet (ODC).

People may also call it a Fiber Distribution Terminal (FDT) or an optical cross-connection cabinet (OCC).

Application: To Integrate fiber optic equipment for interfacing between distribution cables and feeder cables.
Function: To provide the splice and distribution space and be used as a junction box.

Fiber Splitting Cabinet

Application: To ensure a secure transition point from the passive optical network (PON) to the subscriber drop.
Function: To split the fiber signal and used as a fiber splitter hub

The FDC converts the distribution cable into individual cables, extending end-user connectivity.

For this purpose, The deployment of Fiber Distribution cabinets is nearly the same as fiber cable deployment, which is along the roadside or at the corner.

Sometimes, People also call them traffic lights of fiber cables.
