The ABCs of Fiber Enclosure Choosing Considerations

Posted on by FS.COM

All fibers are eventually terminated, spliced, patched and stored in some sort of fiber enclosure. There are thousands of fiber enclosures suppliers in the market to offer all kinds of fiber enclosures. How to choose a good one from them? Knowing your ABCs is critical in choosing the right enclosure for your network. “A” is for accessibility. “B” is for bend radius control and “C” is for compact design. In this article, I will discuss how to choose a reliable and good performance fiber enclosure from these three aspects.

Accessibility
Can it be a good fiber enclosure if you cannot access a specific fiber or connector without disturbing neighboring “active” fibers? The answer is NO. The ability to access the enclosure in order to add cables, without moving/disturbing “active” fibers already installed within, has been no simple task. For some fixed fiber enclosures, insertion and removal of fiber adapter panels are not very easy. When we do this, we may place additional pressure on fiber patch cables, resulting in high attenuation. FS.COM high-density FHD series fiber enclosure (shown in the figure below) makes access to the connections easy via a fixed tray that can be released and slide-out of the front or rear of the enclosure, which increased access between ports and enabled the ease of moves, adds, and changes for fiber optic network.

Bend Radius Control
One of the most important considerations when installing fiber optic cable is maintaining the minimum bend radius. Bending a fiber cable excessively may cause the optical signal to refract and escape through the cladding. It could also cause permanent damage by creating micro cracks on the delicate glass fibers. And when over bending interferes with light transmission, the resulting increased attenuation compromises the integrity of your valuable data. Therefore, bend radius control clips or bend radius guides must be installed on most fiber enclosures to help maintain proper bend radius control of fiber patch cords from patch field to vertical fiber manager. Picture below shows FS.COM high-density FHD series fiber enclosures installed with the bend radius control clips. We can see that the bend radius control clips provide ample bend radius protection for fiber cables exiting out of the enclosure.

Compact Design
There is a definite trade-off between density and accessibility. Many new designs fiber enclosures were developed and deployed, but the outcome has not been very promising nor user-friendly. Accessibility was greatly sacrificed with these new dense enclosures. The FS.COM has succeeded in designing a high-density enclosure that is compact yet accessible. Our high-density FHD series fiber enclosures combine splicing and patching in the same shelf and can hold fiber adapter panels or MTP cassettes in the same shelf, which provides a high-density flexible and modular system for managing fiber terminations, connections, and patching in data center application to maximizing rack space utilization and minimizing floor space.

Conclusion
Select a good fiber enclosure based on the ABCs mentioned in this passage may help a lot. A feature-rich fiber enclosure may cost a bit more than the “bare bones” box, but it will save you a hundred-fold in the long run considering the revenue loss from an interrupted transmission. FS.COM high-density FHD series fiber enclosures are compact design and provide good accessibility and reliable bend radius protection, which can accommodate a maximum of 288 fiber ports in a 4U space.
