Fiber optic cross connect cabinet is an outdoor optical equipment that is especially designed for outdoor optical nodes in access network and widely used in the installation of various equipment in the communication system. Outdoor cross-connect cabinet is the best choice for cross-connecting outdoor optical cables. The cabinets offer ideal environment for fibers to be spliced and well organized under any outdoor environment. The Cross-connection Cabinet can be applied in active link with trunk optical cables and cable distribution, accomplishing fusion, storage, distribution and dispatch for the cables. Its capacity can be flexibly customized as required and built-in direct splice unit is capable for providing direct connection function. It also can able to counter abrupt climate change and extreme environment. It is suitable for outdoor light splitter in FTTH application, provided with light splitting function, easy for installation, safety in use and reducing costs. Cross connect cabinets allow for termination of and cross-connections between cabling elements. These enclosures provide a wide array of functionalities that meet your business and budget requirements. Integrating systems such as putting DSLAM and cross connect chambers in a single enclosure reduce deployment cost and simplify transition to digital services. These are integrated interface systems that include housings, terminal fields, and cables to provide interface between feeder and distribution cables. Some enclosures integrate a protective, ventilated compartment for weather-hardened DSLAM electronics with a weather-sealed compartment for cross connect fields in a single enclosure. They can either be configured as aerial enclosures with a cross-connect capacity range of 200 to 900 pairs or as pad-mount types that can range from 400 to 1200 pairs. Some units allow upgrade of active DSL network and increase the termination capability for an existing cross connect cabinet without disrupting service or circuit downtime, reducing installation expense and labor costs. The cabinet has the functions of fiber distribution, splice, storage and dispatch. It has dogged performance of resisting the open-air environment and can resist severe climatic changes and serious working environment. The protection grade reaches IP65. The cabinet is made from quality stainless steel. It has not only excellent performance of anticorrosion and aging resistance but also pleasing appearance. The cabinet has the advantages of small volume and large capacity of 288 cores.
