Indoor Fiber Optic Cabinet

Indoor fibre optic cabinet finds application in protecting critical junctions just before the last mile fiber optic network. They are made of weather-proof, vandalism-proof material and security to provide a safe housing to telecom equipment, fibers, stacks, servers, etc.

Product Details:

An indoor fiber optic cabinet is a piece of equipment used to distribute fiber optic cables within a building or facility. It typically contains a variety of components, including fiber optic splitters, patch panels, and cable management hardware.

The cabinet is designed to provide a secure, controlled environment for fiber optic cables, protecting them from environmental factors such as moisture, dust, and temperature changes. It also provides a central location for network operators to manage and maintain fiber optic connections.

Indoor fiber optic cabinets can vary in size and configuration depending on the specific needs of the network. Some cabinets may be small and designed to handle just a few fiber optic connections, while others may be larger and more complex, with multiple layers of cable management and a greater number of connections.

Overall, an indoor fiber optic distribution cabinet plays an important role in the reliable and efficient distribution of fiber optic connections within a building or facility.

How to configure a Fiber Optic Cabinet?

Step 1: You need to choose the integral splicing tray which with 12 fibers or 24 fibers, which can be flexibly installed into the cabinet. Or the 19inch integrated ODF unit which full configured with the splice trays.

Remark: An splice tray with ports of duplex LC adapter size can be installed with duplex LC/SC adapters. An splice tray with ports of ST adapter size can be installed with both ST adapters and FC adapters
12 Fibers of Splicing Tray with LC/UPC Adapters
24 Fibers of Splicing Tray with SC/APC Adapter
19inch ODF unit configured with Splicing Tray

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 cabinet capacity, you can choose 144 cores, 288 cores, 576 cores, and 720 cores for your requirements.
