Blockless vs ABS Box PLC Splitter: FTTx Guide
Choosing the right fiber components is vital for a stable network. However, many engineers struggle to choose between a Blockless vs ABS Box PLC Splitter. Both styles have unique benefits for FTTx deployment. In this guide, we will compare their size, protection, and usage.
Why Compare Blockless vs ABS Box PLC Splitter Styles?
Planning an ODF or a street cabinet requires careful thought. Specifically, you must balance space and durability. A Blockless vs ABS Box PLC Splitter comparison helps you pick the right tool for the job. First, let’s look at the mini-module design.
1. The Blockless PLC Splitter: Best for Tight Spaces
The blockless type is very small. Therefore, it fits easily into splice trays. In addition, it uses a stainless steel tube to hold the fiber.
Small Size: It saves a lot of room.
Splicing: Most technicians use it for fusion splicing in closures.
Cost: It is often the most affordable option.

2. The ABS Box PLC Splitter: Superior Protection
Meanwhile, the ABS Box style uses a hard plastic shell. This shell protects the fragile glass fibers inside. As a result, it is much stronger than the blockless version.
Strong Shell: The box prevents physical damage.
Plug and Play: It often comes with SC APC or SC UPC connectors. However, before selecting, ensure you understand the difference between APC vs UPC fiber connectors to keep your signal clean.
Versatility: You can mount it on walls or inside outdoor cabinets.


3. Blockless vs ABS Box PLC Splitter: The Main Differences
To help you choose, we have listed the main factors below.
First, consider the environment. If you have a crowded tray, choose the blockless type. However, if the fibers might move, choose the ABS Box. Second, think about the installation. ABS boxes are easier to manage without splicing tools.
Comparison Table: Style Comparison
| Feature | Blockless Type | ABS Box Style |
| Protection | Basic (Steel Tube) | High (Plastic Box) |
| Best For | Splice Trays | Wall Mounting |
| Density | Very High | Medium |
Which One Should You Choose?
In conclusion, the best choice depends on your specific installation environment. If you have a lot of room and need easy maintenance, the ABS Box is excellent. On the other hand, if you are working with a crowded distribution frame, the Blockless type is the winner.
Furthermore, don’t forget the connectors. Using LC APC or LC UPC options can also help save space. Finally, always check the APC vs UPC standards to reduce signal loss.
