Overview
		
	
Optical distribution modules are designed for the purpose of optic fiber organization, storage and fiber optic fusion protection within optical cable distribution frame, patch panels, optical cable outdoor cabinets etc.
		
	
	
Connecting the DDCTool board to multiple DDCs
	
In the case of only one DDC, a direct connection between the DDCTool board and the DDC is sufficient.
	
If there are several DDCs and only one PC, YPC111A optical distributors can be used between the DDCTool board and the DDCs. YPC111A has one connection for the DDCTool board and four connections for the DDCs or lower level optical distributors. When using the YPC111A board and plastic fibre cable, the maximum length between the boards is 20 metres.
	
If the lengths between the DDCTool boards are over 20 metres the YPC115A board and glass fibre cable should be used. The maximum length in this case is 1000 metres.
	
Optical distributors can be connected to a tree or chain form. The height of the tree / length of the chain depends on the number of DDCs in the system (max number of DDCs is 249).
	
Optical distributors use +24 V auxiliary power

Summary Overview
Optical distribution modules, like the YPC111A, organize and protect fiber connections within various setups and allow for flexible configurations (tree or chain forms) to connect multiple DDCs with specific length and power requirements.
