Introduction to the ODC-20 cabinet

Information on the ODC-20 cabinet description, features, options, access, and size follows.

General description of the ODC-20 cabinet

The Calix C7 ODC-20 cabinet is an environmentally controlled, aluminum and steel enclosure designed to deploy the Calix C7 in outdoor terminal locations. The cabinet can be configured for purely copper, fiber, or a combination of both with flexibility for field migration from copper to fiber.

The Calix ODC-20 cabinet consists of a main cabinet sitting on a battery compartment base. The main cabinet houses three compartments, an equipment compartment, splice compartment, and a copper protection and fiber compartment.

The Calix C7 ODC-20 cabinet is wired for delivery of copper or fiber-based services supporting up to 480 subscribers. The patent-pending integrated cooling system combines low power DC cooling blowers with advanced air-to-air tubular heat exchangers to dissipate large amounts of heat in very small spaces.

Door description of the outdoor cabinet

The cabinet has three doors - front, rear, and side - as well as battery compartment access panels in the front and rear.

All main compartment doors have 2-point position tamper-proof Telco hex-pin locks, each with provision for a padlock, if required by local site practice. The front battery compartment panel has two tamper-proof hex-key locks, each with provision for a padlock.

The rear door can be removed by accessing it from the front door. No external hardware or pad lock tab is present on the rear door. (Note: For the ODC-20 with the optional extended battery back-up configuration, the rear door has two tamper-proof hex key locks with provision for a pad lock.)
