Sumitomo FC-6S Precision Fiber Cleaver

Before introduce Sumitomo FC-6S fiber cleaver, let’s talk about what is optical fiber cleaving? Simply put, optical fiber cleaving is the art of cutting glass optical fibers at a perfect 90°angle with a mirror like surface. This isn’t as easy as it sounds. As we know the quality of the bare fiber end face will determine the quality of the joint of the fibers in the fiber optic fusion process, and the joint point quality means higher or lower attenuation of the fiber connection line. So the fiber cleaver is very important in the fiber splicing process, it works together with the fusion splicer to meet the end needs.

Why do we need to cut the fiber at a perfect 90°angle at all? Well, this is required when we want to fuse two optical fibers together. Optical fiber fusion splicing always requires that the fiber tips have a smooth end face that is perpendicular to the fiber axis. The cleave quality is very important in determining the fusion splicing loss. This is especially true for specialty fibers such as erbium-doped fibers and dispersion compensating fibers.

The basic idea of optical fiber cleaving is first to scratch the fiber with a very hard diamond edge scribing tool, which induces a sufficiently large surface crack, then the fiber cleaver applies a tensile stress to the fiber which causes the crack to expand rapidly across the fiber cross section. Some other fiber cleavers apply the tensile stress first and then scratch the fiber with the diamond edge scribing tool.

Sumitomo FC-6S Introduction


With the introduction of FC-6 series, Sumitomo now has the utimate tool for single and ribbon cleaving. Built on a robust high quality platform, the FC-6 is ideal for use with fusion splicing or other precision applications, setting a new standard for flexibility and performance.
The FC-6 is available with a single fiber adapter for 250 to 900 micron coated single fibers. It is a simple operation for the user to remove or install the single fiber adapter and alternate between mass and single fiber cleaving.

An optional fiber scrap collector can be installed to help maintain loose scraps resulting from cleaving. The scrap collector works to automatically grab and store the scrap fibers as the cleaver’s lid is raised following a completed cleave.

Fiber Optic Tool- Underground Wire Locator NF-816

When first introduced approximately 40 years ago, underground wire locator needed to do little more than find buried water, gas, or sewer lines. Today, locating has become more complex as telecommunications cables join utility lines in the underground environment. Surprisingly, though, today’s underground cable locators rely on the same basic technology found in their early counterparts–injecting an electrical signal onto the cable being located.

Since its development, the cable locator has generally consisted of two parts–a transmitter and a receiver. The transmitter puts an electrical signal onto the cable or pipe being traced, while the receiver picks up that signal, allowing the locator operator to the trace the signal’s patch and follow the cable being located.

The electromagnetic field created by the transmitter can usually be set to a specific frequency, depending on the type of conductor in the cable. Frequency choices can range from less than 1 kilohertz to about 480 kHz. With this range of frequencies, it is important to keep one thing in mind, according to Jim Grimes, Metrotech regional manager. “You want to start out at the lowest frequency, and if that frequency works, don`t change it,” he explains. “Lower frequencies seem to bleed over less and stay on the conductor you are attached to better.”

While the basic technology for locating hasn`t changed much, the ways for getting the signal onto the cable have. In addition to passive signals, which do not require the use of a transmitter, the three most common methods of sending signals are direct connect, general induction, and inductive coupling. In the inductive coupling method, the cable must be grounded to form a complete circuit path.

As its name implies, the direct-connect method allows you to physically attach your transmitter to the cable to be located. That may mean connecting at a cabinet or a pedestal and then gaining access to the shield that surrounds the cable, which is usually grounded at this point.

If directly attaching to the cable is impossible, then the induction method may be the logical choice. Here, you place the transmitter on the ground directly over the cable. Once the transmitter is turned on, it induces a signal into any nearby conductor within its range. This, of course, can lead to problems if there are multiple cables buried within close proximity because the signal could be picked up on a cable other than the one you are trying to trace.

Although inductive coupling doesn`t let the user directly connect to the cable, it provides a higher level of confidence than does general induction. It uses a donut-shaped coupling device that surrounds the cable and emits a signal onto the cable.

FiberStore offer NF-816 underground wire finder, it is designed to locate the path of non-energized wires behind walls and underground. The NF-816 underground cable wire locator can locate a specific circuit breaking, point out wires before drilling and verifying dig sites underground. This underground wire tracer effective range is up to 3 feet deep and up to 1000 feet in length.
