• Multi-core branch cable: There are 2 or more trunk fibers, and corresponding branches.
• Pre-terminated branch cables: The trunk and branch fibers have been pre-terminated with connectors.
• On-site splittable branch cables: The main trunk and branches can be split on-site according to needs.

Differences in applicable scenarios of various types of fiber optic branch cables:

• Single-core branch cable: suitable for small-scale user access, and the wiring requirements are relatively simple. Branches are usually connected by direct welding or mechanical docking.
• Multi-core branch cable: It is suitable for large-scale user access and can introduce more branches at one time. Branches usually use fiber optic connectors to achieve fast splice-free connections.
• Pre-terminated branch cables: Connect the connectors in advance and quickly complete branch connections on site. Suitable for scenarios that require rapid deployment, such as FTTH, FTTx, etc.
• On-site splittable branch cables: The trunk and branch optical fibers can be flexibly split according to actual needs. Suitable for scenarios where wiring scheme changes are frequent.

Characteristics of different optical fiber branch cables in optical fiber networks:

• Improve the efficiency of fiber optic network deployment and shorten the construction cycle.

• Clean the environment around the cable promptly to prevent debris from causing mechanical damage to the cable.
• For branch cables used for a long time, the aging degree needs to be checked regularly and replaced if necessary.

Common faults of optical fiber branch cables and their troubleshooting measures:

• The optical power of some branch ports decreases: Check whether the corresponding branch connector is damaged or contaminated and needs to be cleaned or replaced. Check whether the trunk optical fiber has increased loss caused by macro bending or damage.
• Mechanical damage to branch cables: Check whether the outer sheath of the cable is damaged and repair the damaged parts. If the damage is severe, the entire branch cable may need to be replaced.
• The connection of the branch connector is unstable: carefully check whether the connector is plugged in and out properly to ensure that the connection is firm and reliable. If the connector itself is damaged, it needs to be replaced with a new fiber optic connector.
