May 30, 2018

As the demand for computing power grows rapidly, it’s vital for data center operators to look for the high-density equipment that can offer higher performance without needing to expand into a larger physical space. Fiber enclosure, or fiber splice box, as a necessary fiber cable management component, is widely used in data centers to house, organize, manage and protect fiber optic cables. Simultaneously, these fiber optic enclosures come in different configurations such as rack mount, wall mount enclosure, and indoor or outdoor enclosure. Among these different configurations, rack mount fiber enclosure is the most commonly used in data centers.
