How to choose a fiber distribution box?

When you want to select one fiber distribution box, you’d better consider all the features mentioned above to find the most appropriate one.

You have to determine three things beforehand, i.e., the capacity of the fiber optic distribution box based on your projects, like an 8-core distribution box, the placement you want to deploy it, wall mount or pole mount, and finally, a loaded or unloaded version to buy.

What’s the difference between ODF (optical distribution frame), OFPP (optical fiber patch panel), and OFDB (optical fiber distribution box)?

I recently came across this question, as they are much alike in functions, sometimes even appearance. I observed there’re lots of guys also get confused by the relationship between these three pieces of equipment. Therefore, I want to talk a little about this question.

First, let’s summarize their similarities.

Similarities between ODF, OFPP, OFDB

Generally speaking, most of the functions they provide are similar, listed as below:

Termination: fusion splicing/mechanical splicing with fiber pigtails or a fiber connector approach.

Splitter, splitting an optical signal into more parts to branch.

Appropriate space for storage of excess patch cables or pigtails allows for minimum bending radius.

Protection of splice joints, adapters, and other components.

Better cable management.

Given the strong likeness between them, no wonder people mix them up with each other.

As we’re more concerned with the differences between ODF, OFPP, and OFDB, thus we’ll go into the distinctions between them.

Differences between ODF, OFPP, OFDB

Concisely, there’re two important aspects used for differentiating them. One is the usage environment, and one is the dimensions.

usage environment

Besides a considerable overlap of usage environments, ODFs are typically used in high-density cabling systems like data centers, service rooms, etc. Optical fiber patch panels are often used in intra-building wiring systems, typically used for LAN applications. OFDBs are often used in FTTH and FTTB networking systems to provide the local loop used for last mile telecommunications.


With some exceptions, ODFs are the biggest among them, and it even houses patch panels as accessories within it, while it’s hard to compare the last two pieces of equipment, as they all have lots of varieties of shape and sizes. The bigger the size, the larger the number of ports.


So, this is it. We’ve introduced the basics of the fiber distribution box, and it would be helpful for you to choose the best appropriate one. In addition, if you still have some questions about the fiber distribution box, feel free to leave a comment.
