Protect fiber optic cable connections：The joint box provides physical protection for the fiber optic cable connection parts to prevent damage to the fiber optic cable caused by external environmental factors such as moisture, dust, chemical corrosion and mechanical damage.
Provide a stable transmission environment：The joint box is sealed to prevent moisture and dust from intruding, ensuring the transmission quality of fiber optic signals.
Core functions：Synchronous power supply and data transmission While transmitting data signals, POE switches can provide DC power to terminal devices such as IP phones, wireless APs, and network cameras without the need for additional power wiring.
Simplified wiring architecture：By integrating power cables and network cables, POE switches significantly reduce wiring complexity, especially for scenarios where it is difficult to deploy power sockets (such as ceilings and outdoor areas), and the maximum power supply distance can reach 250 meters.
Improve system reliability：The centralized power supply design reduces the risk of failure caused by decentralized power supplies, and supports remote power management for unified maintenance.
ODF（Optical Distribution Frame）
ODF rack's official name is Optical Distribution Frame. It is mainly used in optical fiber communication systems for the fixation, protection, termination and line adjustment of optical cables
Functions and uses of ODF racks：ODF racks play an important role in optical fiber communication systems.
Fiber cable fixation and protection: ODF racks can fix optical cables to prevent them from being affected by external forces during transmission.
Fiber cable termination: Connect the optical fiber in the optical cable to other devices or systems.
Line adjustment function: Facilitate the connection and adjustment of optical fibers, and improve the flexibility and maintainability of the network.
Fiber core and pigtail protection: Provide protection for optical fiber connectors to ensure the stability and reliability of signal transmission
These three accessories are common accessories for optical cables. Today we briefly introduce their functions and uses, so that we can understand the communication process more quickly.
