S0010270 OptiX OSN 1500B

The OptiX OSN 1500 consists of the cabinet, subrack, and boards.

The OptiX OSN 1500 can be installed in an ETSI cabinet (300 mm or 600 mm deep) or a 19-inch standard cabinet. It can also be installed against the wall.

The OptiX OSN 1500 uses various types of boards and thus forms the system frame where the cross-connect matrix is the core. The system frame of the OptiX OSN 1500 has the following units:

• SDH interface unit
• PDH interface unit
• DDN interface unit
• Ethernet interface unit
• Resilient packet ring unit
• ATM interface unit
• SAN interface unit
• WDM unit
• SDH cross-connect matrix unit
• Synchronous timing unit
• SCC unit
• Overhead processing unit
• Auxiliary interface unit
• Power interface unit
• Optical amplifier unit

• Figure 1 shows the structure of the OptiX OSN 1500B subrack.

• 

• The OptiX OSN 1500B subrack is of a two-layer structure. The subrack consists of the slot area for processing boards, slot area for interface boards, slot area for the auxiliary interface board, power supply area and fan area.

  • Slot area for interface boards: This area is used to house the tributary interface boards and Ethernet interface boards of the OptiX OSN 1500B.
  • Slot area for processing boards: This area is used to house the line, tributary and Ethernet processing boards of the OptiX OSN 1500B.
  • Fan area: This area is used to house one fan module, which dissipates the heat generated by the equipment.
  • Slot area for the auxiliary interface board: This area is used to house the auxiliary interface board, which provides alarm interfaces, orderwire phone interface, management and maintenance interface, and clock interface.
  • Power supply area: This area is used to house two PIU boards, which are used to supply power for the equipment.
  • Cable routing area: This area is used to route fibers and cables in the subrack.

• The functions of each subrack area are as follows:

  1. Interface board area	2. Power supply area	3. Fan area	4. Processing board area
  5. Processing board area	6. Cable routing area	7. Ear bracket	-
