Bosch DCN Next Generation - Optical network design

Optical network design
This chapter tells how to design the optical network.
Calculation tool
The calculation tool makes the planning and design of the optical network easier. You can find
the calculation tool on the DVD that is supplied with your system.
Limits
Limit 1: Number of nodes
The maximum number of nodes that you can connect to the optical network of the central
control unit, that has 2 nodes, is 61. Refer to Control capacity, page 78 to see how many
nodes the devices have.
Limit 2: Number of WAPs
The maximum number of DCN-WAP Wireless Access Points in the optical network is 1.
Limit 3: Cables
– The maximum length of the standard network cable LBB4416/xx (Plastic Optical Fiber)
cable is 50 m.
– If longer cables are required, the PRS-FINNA can be used to convert from plastic to glass
and vice versa. The total maximum cable length of Glass Optical Fiber (GOF) plus the
Plastic Optical Fiber (POF) is dependent on the total length of GOF and POF plus the
equivalent cable length per used device. Refer to Control capacity, page 78. This should
not exceed
2090 m. Refer to Optical fiber length, page 80.
– The minimum bend radius of a 90 degree bend in a POF cable is 25 mm.
– The minimum coiling radius of a POF cable is 100 mm.
