Fiber optic patch panel are essential for long-distance transmission in low-voltage engineering, as only fiber optic patch panel can extend network transmission further. Today, we will explore the supporting products of fiber optics, specifically the Optical Distribution Frame (ODF), which is used in fiber optic communication systems to terminate and distribute trunk cables at the central office. It makes it easy to connect, distribute, and manage fiber optic lines.
Common ODF frame capacities include 12-core, 24-core, 48-core, 72-core, 96-core, and 144-core.
The fiber tray in ODF can be selected based on the type of cable and interface, with options like FC, ST, SC, and LC fiber couplers, as well as indoor/outdoor single-mode, multi-mode, and 10G OM3 cables.

The fiber distribution frame, serving as the terminal equipment for the cable line, should have four basic functions. Securing function: After the cable enters the rack, its outer sheath and reinforcing core are mechanically secured, grounding protection components are added, end protection is processed, and the fibers are grouped and protected. Fusion function: Fibers drawn from the cable are fused with the tail cable, excess fibers are coiled and stored, and the fusion joints are protected. Allocation function: Connectors on the tail cable are plugged into the adapter to connect with the optical connector on the other side, creating an optical path. The adapter and connector should be able to plug and unplug flexibly; the optical path can be freely allocated and tested. Storage capability: Provides storage for various cross-connected optical connecting lines between racks, allowing them to be placed neatly and orderly. The fiber distribution frame should have appropriate space and methods to make the wiring of these optical connecting lines clear, easy to adjust, and meet the minimum bending radius requirements.
Why is the fiber tray called an integrated fusion tray? It includes a plastic tray, fiber couplers, and fiber pigtails (mostly using bundled tails).
Introduction to bundled pigtails: These are also known as bundled tails, featuring a connector at one end and a fiber break at the other. They are connected to other cable cores through fusion and are commonly found in fiber terminal boxes and fiber distribution frames, used to connect cables to terminal equipment.
The color coding of bundled tails generally follows the standard color spectrum sequence.
The fiber coupler is a device that allows for detachable (active) connections between fibers. It closely aligns the two end faces of the fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber, minimizing the impact on the system by intervening in the optical link. Commonly used fiber couplers are as follows:
Among them, the FC coupler in ODF is generally replaced with a square coupler.
Next, let's examine the practical application of ODF.
First, strip the fiber optic cable,
secure it,
perform the fusion,
Put the fiber optic cable in the fiber tray.
