Optical network design

This chapter tells how to design the optical network.
4.2.1

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.
4.2.2

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 Table 4.6 to see how many nodes the devices
have.
Limit 2: Number of WAPs

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 Table 4.6. This should not exceed
2090 m. Refer to Section 4.2.6 Optical fiber length.
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.
