Product Details:

Rack-mountable design: The frame can be mounted in a standard 19-inch equipment rack.
Size: The frame can come in different sizes, from 1U to 3U, depending on the number of fiber optic connections needed.
Capacity: The frame can support a varying number of fiber optic cables, ranging from 12 to 144 fibers or more, depending on the size of the frame.
Connector types: The frame can support different types of fiber optic connectors, such as LC, SC, ST, FC, and MTP/MPO.
Cable management: The frame includes cable management features such as cable guides, trays, and ties to organize and protect fiber optic cables.
Front and rear access: The frame can have front and/or rear access panels for easy access to the fiber optic connections.
Material: The frame is typically made of metal (such as steel or aluminum) for durability and protection.
Optional features: Some Rack-mount Fiber Optic Distribution Frames may include additional features such as splice trays, patch cords, and adapter plates.

Types of Fiber Optic Distribution Frame

According to the structure, ODFs can mainly be divided into three types, namely Rack-mount ODF, Wall-mount ODF, and Cabinet-mount ODF.

Cabinet-mount Optic Distribution Frame

How to configure a Rack-mount ODF or Fiber Optic Patch Panel?

Step 1: You need to choose the integral splicing tray which with 12 fibers or 24 fibers, which can be flexibly installed into the Rack-mount ODF, and the fiber optic patch panel has already deployed the splice tray for the 19inch 1U size for 12 fiber or 24 fiber.

Remark: An ODF with ports of duplex LC adapter size can be installed with duplex LC/SC adapters. An ODF with ports of ST adapter size can be installed with both ST adapters and FC adapters

Step 2: Choose the correct connectors for the Splicing Tray, it supports LC/SC/ST/FC adapters which shows below.

LC connector
1.25mm LC is mainly used for matching SFP/SFP+/XFP transceivers. Higher-density connections.
SC connector
2.5 mm SC is mainly used for EPON, GPON, GBIC, X2, and XENPAK transceivers, telecom, and datacom.
ST connector
2.5 mm ST is mainly used for Military, campuses, FTTH, datacom, and corporate networks.
FC connector
2.5 mm FC is mainly used for Telecom, datacom, single-mode lasers, and measurement equipment.

Step 3: Choose the polish type of connectors. There are two types of connector polish, UPC and APC.

Two Polish Types for Various Signal Sensitivity Demands.
Please Note. UPC and APC connectors couldn't be mated together - they are not compatible with each other.
No angles, with high return loss than APC polishment, are mainly used for used for TV, telephony, and data systems.
With 8 degrees angle, has better performance(lower return loss) than APC, which is mainly used for FTTH, PON, WDM systems, etc.

Step 4: According to the number of fiber strands, Optic fiber patch cords with connectors can have two types of strands: simplex or duplex.

Choose which type of strands you will need, Simplex or Duplex?

simplex connector


A simplex cable has one single strand of fiber with one simplex connector on each end. One end is a transmitter, the other end is the receiver, and these are not reversible. This is commonly used for Bidirectional (BIDI) fiber optic transceivers. Simplex cables are less expensive and can transmit at higher speeds.
Duplex connector


A duplex cable has two strands of fibers with a duplex fiber optic connector, One strand transmits one way, and the other strand transmits back the opposite way. This is a huge advantage over simplex because it can transmit simultaneous bidirectional data. This is a huge advantage over Simplex because it can transmit simultaneous bidirectional data.

Step 5: According to the fiber count capacity, you can choose the fiber from 12 to 144 depending on your requirements. Also depending on the number of splicing trays.
