Fiber optic Splice trays are necessary to support and protect individual fusion splices or mechanical splices.
Splice trays are available for all different types of splices, such as 3M, Corning, AMP and Siemon company mechanical splices, bare fusion splices and heat shrinkable fusion splices etc.
Typically, the splice trays must match the type of splice used. A splice tray designed to hold mechanical splices generally cannot be used for bare fiber fusion splices or heat shrinkable fusion splices. Although there are splicing chips that you can buy to make them work, it is not the ideal way.
Standard splice trays can hold up to 12 splices, and you can use multiple splice trays together for fiber optic cables with higher number of strands. The splice tray has room to mount excess fiber and fiber splices.
Loose fiber tubes enter the splice tray at one end and secure to the splice tray. The loose tube stops at the end of the splice tray and the individual fibers are exposed and spliced within the splice tray.
NOTE: Bare fibers without protective tubes should never be exposed outside of a splice tray. When splicing a large fiber optic cable with more than 12 strands of fiber, appropriate shield tube splitters must be used when routing bare fibers to another splice tray.
Be very careful when mounting the splices inside the tray. The minimum fiber bend radius requirement should always be observed.
The following is a sample image of a splice tray with fusion splices mounted inside.

2. How to use the fiber optic Splice Tray
The fiber optic splice tray is designed to provide a place to store fiber cables and splices and prevent them from being damaged or misplaced. Also called as junction box or splice organizer. The splice tray does not contain any technical function, and the design is simple. In addition, it has a very low price so that people can pay. However, the importance of the fiber splice tray to protect the fibers is significant. And the skills necessary to use the fiber splice cassette are not as simple as you think.

2.1 Fiber Splice Tray Function
With such a simple structure, you may wonder how the fiber splice casstte really works. Here is the brief introduction of its working function: the incoming fiber is brought to the splice center where the outer sheath of the cable is removed. The fibers are completely wound around the tray and inside a splice holder. Different supports are available for different types of splices. The fibers are spliced in the output cable if it is an intermediate point or in pigtails if it is a termination point. These, too, wrap completely around the tray and then feed from the tray.

2.2 Installation procedures
The installation procedures can be divided into five steps:
Step One, route the fibers to the splice tray using spiral transport or fiber furcation tubes and secure with cable ties.
Step two, splice fibers per local practice.

Step three, place spliced fibers into the sleeve holders arranged by color code.

Step four, carefully coil the outgoing fiber slack into the tray (coil 1).

Step five, carefully coil incoming fiber slack into the tray (coil 2).
Fiber splice trays are generally placed in the middle of a path where cables are required to be attached or at the termination and at the patch panel points at the end of cable runs. Additionally, splices can be placed in a splice tray which is then placed inside a splice closure for OSP (off-site) installations or a patch panel box for local applications. As for indoor application, fiber splice trays are often integrated into patch panels to provide connections to the fibers.
As protection for fiber splices, the fiber splice tray is arguably the most cost-effective device. This simple design solves many problems when installing fiber cables. Welink offers splice trays of different shapes with different fiber capacities at a competitive price.
