OSN 3500

Dear friend!

Slots are used to house boards.

The subrack is the physical subrack of the OptiX OSN 3500. It contains multiple slots. The core part of a subrack is the backplane of the subrack,

A board is a unit that can perform one or more functions. Boards with different functions must be installed in different slots.

The boards communicate with each other through the bus on the backplane of the subrack. A subrack consists of boards installed in multiple slots to form a powerful device.

An independent OptiX OSN 3500 is a subrack. Its slots are divided into two layers: upper and lower. As shown in the following figure:

1. Interface board area: This area houses the interface boards of the OptiX OSN 3500.

2. Fan area: This area houses three fan modules, which dissipate heat generated by the equipment.

3. Processing board area: This area houses the processing boards of the OptiX OSN 3500.

4. Cable routing area: This area houses fiber jumpers in a subrack.

Thanks！
