SUBSYSTEM REQUIREMENTS DOCUMENT

1. Scope. This specification defines the requirements for the external Video Camera System Outboard Cables to be used with Dry Deck Shelters (DDS). The vendor will provide two, different length cables.

2. Background. The Video Camera System under design shall be capable of viewing, to provide situational awareness, the full deployment of underwater payload and displaying the image on a screen inside the host sub for Special Operations Forces (SOF) viewing. The system will comprise of the Subsystems:

Subsystem A: Camera Power Supply

Subsystem B: Outboard camera cables

Subsystem C: Cameras

Subsystem D: Camera mounting brackets

3. Identification. A complete Video Camera System will consist of:

a. (1) AC-DC Power Supply per installed camera

b. Power and video distribution cables (permanently installed on host submarine) and/or distribution equipment to support all installed cameras

c. (1) Outboard cable to provide power to and video from each installed camera

d. (1) Forward Camera (per DDS), aft viewing, mounted on DDS

e. (1) Aft Camera (per Host Sub), forward viewing, mounted on deck of Host Sub

f. (1) Camera mount per installed camera

5. Subsystem B: Outboard Camera Cables.

There will be two different lengths for the outboard camera cables, 90 feet long and 6 feet long. The cables shall incorporate an M24231/3-002 connector on the end that interfaces with the host sub, and a Seacon or Burton 55R1-1508 connector on the end that connects to the camera. The cable shall have a minimum of 4 shielded pairs, capable of transmitting video and DC voltage with minimal loss. The cable shall have properties equal to or exceeding the Basic Electrical, Group A, Group B, and Group C requirements of Reference (a). The cable shall be armored with braided 304 stainless steel shielding with minimum 85% coverage. The outboard camera cables will be manufactured IAW Reference (b) and Reference (c). First Article and Conformance Testing will be IAW Reference (d). The cables are not within the Scope of Certification boundary.

Electrical pinout of the cable shall be:
