Distribution from core to customer
Frames, terminals, and boxesat every level.
ODF at the core, FAT and FDB toward the customer, ATB at the premises — clear, serviceable connection points across the network.
Fittings and hardware
Core frames, access terminals, distribution boxes, and premises termination.
ODF (Optical Distribution Frame)
Rack or wall-mounted frames at the network core or building entry that terminate and patch fibers.
FAT (Fiber Access Terminal)
Pole, wall, or pedestal terminals close to customers, where drop cables connect to the distribution network.
FDB (Fiber Distribution Box)
Boxes that hold splices or splitters and distribute fiber within an area or building.
ATB (Access Termination Box)
Small wall-mounted boxes at the customer's premises where the drop cable terminates.
Adapters, trays, and accessories
Fittings that complete each enclosure.
Why purpose-made fittings matter.
Faults can be isolated at one level, and new customers can be added without disrupting existing ones.

Match to equipment and site.
Network position
Core equipment connects through the ODF, then feeder, FDT, distribution, FAT or FDB, drop, and finally ATB.
Splitters and splices
Splitters sit in FDT, FAT, or FDB enclosures; splices sit in trays.
Cables
Entry ports must suit the feeder, distribution, or drop cable.
Connectors
Adapters and pigtails must match the network's connector and polish type.
Environment
Outdoor terminals must be weather-rated; indoor boxes suit buildings.
Patch cords
Link equipment and terminals to adapters inside each enclosure.
Decisions that get the choice right.
Capacity
Allow for future customers at each level.
Location
Indoor or outdoor, pole, wall, or rack.
Cable compatibility
Check entry ports and cable diameters.
Connector standard
Keep it consistent from ODF to ATB.
Common questions
What is the difference between FAT and FDB?
Both distribute fiber toward customers. FATs are commonly used for access points on poles and walls, while FDBs are often used within buildings or local areas. Exact usage varies by network design.
What does the ATB do?
It gives the customer's drop cable a protected termination point, with an adapter where a patch cord plugs into the ONT.
Can I add customers later?
Yes, if the FAT or FDB was sized with spare capacity.
