ODF patch panel is used to accommodate optical fiber and fiber optic components of the activities of the transfer, its role is mainly used to fix and receive optical fiber, optical fiber termination and installation of optical fiber coupler, but also can protect the optical fiber connector, to prevent it from being damaged , In general, is a protective device. Optical fiber patch panels on the market are also the same as many products, they have common features and different points, different shapes and different specifications. Each manufacturer has its own unique style and main features. So when we are in the choice of fiber optic patch panel, we first consider the factors that are installed on the wall or rack? Is it for horizontal systems, backbone or centralized cabling?
ODF patch panels are normally installed in wiring closets and may be installed directly on the wall for small installations. If the patch panel is used for horizontal systems, its density will be relatively high, centralized fiber optic cabling technology can be formed in the main trunk or horizontal channel, and then use the pull from the work area, interconnection or splicing The cable to the center distributor can produce this channel. When used in a horizontal system or centralized wiring, the optical fiber can be a dual-mode optical fiber or a four-mode optical fiber cable. The backbone fibers can be multimode, singlemode, or hybrid fiber, and these typically use connectors to complement the network hardware.
The number and size of the optical fibers entering the distribution frame takes into account the number and size of the optical fibers entering the distribution frame to ensure that a sufficient number of holes are sized to accommodate the cable glands. With a small package (SFF) connector, a 1U patch panel can accommodate up to 24 duplex connectors or 48 fiber bundles. So how to choose the right patch panel? We need to consider what the problem?
The first thing to consider is cable retention: a certain amount of fiber cable should be retained to ensure a fiber-strength film on the chassis of the distribution frame. This prevents the fiber from being pulled out of the distribution frame and at the same time avoids excessive stress on the cable. The second is its protective properties: Fiber patch panels should provide adequate protection for connectors to prevent accidental contact. And finally, its suitability: Fiber distribution frames should allow the removal of existing connectors and the addition of new connectors or fibers, which must also be able to store and identify non-connectorized fibers from horizontal or trunk cables.
