Understanding Fiber Optic Cleaver Types: Manual, Automatic and Specialized

A fiber optic cleaver is used to cut optical fibers accurately, resulting in clean, flat end-faces for strong splicing with the least amount of loss. It is important to cleave high-quality optical fibers because even minor flaws in the cutting process can cause errors in transmission or weak connections. The stability of the network depends on reliable and consistent cleaving.

Manual fiber optic cleaving tools, also known as "cleavers," are effective for basic splicing or repairs. These types of tools require the user to manually align and score the optical fiber. Therefore, both technicians and fiber optic enthusiasts utilize this type of fiber optic cleaver for smaller jobs, as it is commonly a more affordable option.

Automatic fiber optic cleavers can score and break the fiber in a single action. Automatic fiber optic cleavers can save time in the process and reduce the user error factor, which is why they are favored by those in the telecom world and are used frequently in very busy operations.

Another type of fiber optic cleaver is the FC 6S. This fiber optic cleaver is a specialty version that adds a high-quality cleaving blade design and ergonomic functionality to a fiber optic cleaver. This type of fiber optic cleaver is typically used in laboratories or by customers who require consistent results at a higher level of precision.

Choosing from the different types of fiber optic cleavers often comes down to whether you are doing many jobs in a day, how accurate the cleaving needs to be, and what kind of daily environment you are working in. Each cleaver type will satisfy various users and respective situations, which is a balance of cost, convenience, and precision.

Key Criteria: What Makes a Good Fiber Optic Cleaver?

When selecting a fiber optic cutter for optical fiber cleaving, it's not as simple as selecting a familiar brand name. Blade quality is a priority.
