Hello everyone!
The ODN is an important link in the access network. Nowadays, fiber optical splitters in ODNs also play a crucial role. The advent of fiber optical splitters helps users maximize the performance of optical network circuits. It is one of the most important passive devices in optical links.
So today, let's learn more information about Fiber Optic Splitter.
Basic principles of the Fiber Optic Splitter
Fiber optical splitter is a multi-input and output optical fiber serial connection equipment, especially for passive optical networks (such as EPON, GPON, BPON, FTTX, FTTH, etc.) that connects the main distribution frame and terminal equipment to branch optical signals.
The optical splitter divides optical fibers two to 32 times and reallocates optical signals among multiple optical fibers. This is the origin of optical splitters.
The loss of a single 1 x 32 splitter is lower than any combination of 1 x 2 and 1 x 16 or 1 x 4 optical splitters and 1 x 8 cascaded splitters or 1 x 16 or optical splitters 1 x 4 and 1 x 8 cascaded splitters in the network. With the evolution of optical networks, there is a need for multiple distributions of optical signals.
Type of the Fiber Optic Splitter
Optical splitters can be classified by packaging style, transmission medium, and manufacturing process.
The common and common splitter types are PLC and FBT. The following table lists the differences.
Type | PLC Splitter | FBT Coupler Splitters |
Operating wavelength | 1260nm-1650nm (full wavelength) | 850nm, 1310nm, 1490nm, and 1550nm |
Splitter Ratios | Equal splitter ratios for all branches | Splitter ratios can be customized |
Performance | Good for all splits, high level of reliability and stability | Up to 1:8 (can be larger with higher failure rate) |
Input/Output | One or two inputs with an output maximum of 64 fibers | One or two inputs with an output maximum of 32 fibers |
Housing | Bare, Blockless, ABS module, LGX Box, Mini Plug-in Type, 1U Rack Mount | Bare, Blockless, ABS module |
