What is Fiber Splice Tray

The fiber splice tray is a device used to hold and protect fiber cables and their splices. The design of the fiber optic splice tray is intentionally simple, as it does not need to perform any complex tasks or functions.

What is a fiber splice tray?

Fiber splice trays are specialized devices used to maintain and protect fiber optic cables. They are typically made from a durable plastic material and consist of slots or compartments that hold the individual fiber cables inside the splice cassette. This helps to prevent damage or loss of the fibers, while also making them easier to route within a network.

A variety of different splice tray designs are available, including 12 fiber splice tray and 24 fiber splice tray, which can accommodate larger numbers of fibers. Some optic splice trays may also include additional features, such as holders for buffer tubes or adapters. Overall, fiber optic splice trays are essential components in any fiber optic network and are an important part of ensuring reliable connectivity and performance.

What are fiber optic splice trays used for?

Splice cassettes are typically used in fiber optic networks to route and protect individual fiber cables. They provide a convenient way to manage and organize the many different cables that make up these complex systems, while also helping to prevent damage or loss of the fibers.

How do you route fiber in a splice tray?

Several different methods can be used to route fiber cables in a optic splice tray. One common approach is to lay the fibers side-by-side, with small spacers to keep them separated and prevent crosstalk. Another option is to arrange the fibers in layers, with each layer running perpendicular to the one below it.

Ultimately, the best routing method will depend on your specific needs and preferences, as well as the design of the splice tray itself. Below are the detailed steps to use the tray.

Step 1. Set a pen at 1/4″ for each tube past the tie-down slot and use a buffer tube cutter to cut at the mark. After cutting, take out any excess tubes from every group. Note: LBT wrap should go around the buffer tubes before placing them in the tray.

Step 2. Cut the fibers that need to be spliced so they are 24 to 42 inches long. The 900-micron fibers might have to be cut closer to ich lower end of this range because of how much space the fiber optic splice cassette can hold.

Step 3. Splice two fibers, and store the splice sleeve in the Splice module. Note: Ensure you are routing the fiber correctly by referring to Figure 5 for an example of incorrect fiber routing.

Step 4. Gather the slack fiber and store it at one end of the tray. Fold the fiber loops over on themselves to form a coil roughly three inches in diameter. Lay the coil on the tray around the arcs, as shown as below photo.


Step 5. As shown below photo, direct fibers 1-6 toward one end of the tray and route fibers 7-12 to the other end. Note: Keep a minimum 30 mm bend radius (2-3/8” diameter).


Step 6. Use tray tabs to help keep fibers together.

Step 7. Cover each splice tray with its corresponding protective plastic cover.

Step 8. Take the buffer tubes that have not been cut and coil them before placing them in the provided storage “sock” or basket. Keep the trays close together and use the Velcro fastener strap to secure the sock to the bottom of both trays.

Fiber Optic Splice Cassette features

  • Splice sub-assemblies have a groove plate that goes around the outside. This holds trays with organizers for splices.
  • Fiber channels keep fiber optic cables in place while protecting their bend radius.
  • Groove plates have slots that help guide fiber to and from the organizer trays.
  • Touchless fiber inspection is possible with clear covers.
  • This allows for a single circuit of fiber to be stored on the splice tray without having to cut the fiber.
  • This splicer works with most types of splices and doesn’t need any special type of fiber to work.
  • This product is made from high-quality plastic that is engineered to last. It is made in North America, so you can be sure that it meets the highest safety standards.
  • You can choose between a 12-tray or 24-tray option for small or large fiber runs.
  • The tension-hinged trays stay open while routing fiber, making it easy for you to access and install the fiber.
  • This is a universal splice tray that can be used for single fusion, ribbon, or mechanical splicing applications. The tray has snap-in splice clips to make the process easier.
  • Stackable design means that you can add more of what your application needs when it needs it.
  • The tray is UL-listed and industry-standardized, which means it is reliable.
