Basic structure of ODN in FTTH

• ODN (Optical Distribution Network): FTTH optical cable network based on PON equipment, used to provide optical channels between OLT and ONT.
• PON (Passive Optical Network): Passive Optical Network
• OLT (optical line terminal): Optical line terminal, a terminal device used to connect optical fiber trunk lines.
• FMS (Fiber management System): Fiber management system for ODN line testing and fault location.

Features

1. It is suitable for overhead, buried, and wall-mounted installation of pipeline manholes.
2. The built-in laminated fusion splicing tray is easy to open and can be removed for operation, which is convenient for line installation and maintenance.
3. The internal storage space is large, which can meet the storage and protection of residual fibers.
4. The shell material of the product is made of high-strength engineering plastic ABS, which is flame-retardant, waterproof, and impact-resistant, and can withstand harsh field climates.
5. The box body is sealed with vulcanized sealing strips for automobiles, which is resistant to corrosion and the influence of high and low temperatures. At the same time, it uses high-quality rubber seals to meet the requirements of IP65-IP68 protection grades.

Typical application scenarios of optical cable splice boxes

The optical cable splice box, also known as the optical cable protection box, is an indispensable product in the optical fiber communication system. It is mainly used in branching and splicing the leading optical cable in the optical fiber communication network and plays a vital role in protecting the incoming and outgoing optical cables. Because of its good sealing performance, small size, and good re-packaging effect, it is prevalent. It can connect multiple optical cables at the same time and has the functions of distribution, switching, and built-in optical splitter according to requirements to optimize the line. It is widely used in telecommunications, electric power, radio and television, and many other fields.

Optical cable splice box usage scenarios

• The use form can be divided into ordinary optical cable joint box, photoelectric composite optical cable standard box, and split optical cable box.
• According to the product structure, it can be divided into horizontal/horizontal splice closure (fiber optic horizontal splice closure), Vertical / vertical splice box (fiber optic vertical splice closure).
• According to the use of optical cable, it can be divided into overhead, pipeline (tunnel), and direct burial.
• According to the optical cable connection method, it can be divided into straight-through connection and branch connection.
• The sealing method can be divided into mechanical seal and heat shrink seal.
• According to the capacity, it can be divided into 24 cores or less, 36 cores or less, 48 cores or less, 72 cores or less, 96 cores or less, 144 cores or less, and 288 cores or less.
