These products are all specialized enclosures for telecommunications infrastructure. Here is a summary of their primary functions:

• Communication Cabinet:​ A general-purpose enclosure for housing and protecting active network equipment (like routers, switches) and passive components (like patch panels) in central offices or data centers.

• Outdoor Integrated Cabinet:​ A rugged, weatherproof cabinet designed for harsh outdoor environments. It integrates and protects multiple subsystems—such as power, transmission, and access equipment—into a single, compact unit, often used in sites like cell towers or roadside installations.

• Transmission Cabinet:​ Specifically designed to house and protect transmission equipment (e.g., SDH, OTN, microwave devices). Its key role is to ensure the stable and reliable long-distance transport of high-capacity voice, data, and video signals across the network backbone.

• Communication Power Cabinet:​ Dedicated to housing power supply and distribution systems for telecom sites. It contains components like rectifiers, batteries, and distribution units to provide stable, backup-protected DC power to all the communication equipment within a facility.

In essence, they work together: the Power Cabinet​ provides energy, the Transmission Cabinet​ moves data over long distances, the Communication Cabinet​ manages and distributes data locally, and the Outdoor Integrated Cabinet​ often combines these functions in a single, hardened package for remote locations.
