3Optical network design
3.1Introduction
The DCN Wireless has three parts: the wireless network, the DCN and the optical network. This chapter tells how to design the optical network.
3.2Calculation tool
The calculation tool makes the planning and design of the optical network easier. You can find the calculation tool on the
3.3Limits
Make sure that these limits are not exceeded when you make the optical network:
Limit 1: Control capacity
The maximum number of nodes in the optical network is 63 (refer to section 3.4).
Limit 2: Number of devices
The maximum number of devices that you can connect to the optical network of the central control unit is 16. The maximum number of
Limit 3: Power capacity
The maximum power that the optical network sockets of the central control unit can supply is 65 W (refer to section 3.5).
Limit 4: Cables
Refer to section 3.6:
•The maximum length of a POF cable is 50 m.
•The maximum cable length (POF and GOF) of the optical network is dependent on the number of nodes in the optical network.
•The minimum bend radius of a 90 degree bend in a POF cable is 110 mm.
•The minimum coiling radius of a POF cable is 110 mm.
3.4Control capacity
Each device in the optical network has a number of nodes (refer to table 3.1). The maximum number of nodes in the optical network is 63.

3.5.1Introduction
Each device uses power and most devices do not have an independent power supply.
3.5.2Power consumption
The table shows the power each device in the optical network uses.
