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 CD-ROM that is supplied with your system.

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 DCN-WAP Wireless Access Points in the optical network is 1.

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.

Note

The Integrus transmitters do not use power from the system.
