PCVFL Description
PCVFL (Precision Coupled Visual Fault Locator) is a light-weight, hand-held tool used to quickly troubleshoot faults
in the near-end of both singlemode and multimode fibers, as well as used for port identification and fiber continuity.
The PCVFL holds its own against the best visual fault locators (VFL) in the industry. As with any quality VFL, the
PCVFL uses a precision-coupled laser diode to inject a maximum amount of optical energy into an optical fiber. A
multi-million dollar semiconductor machine is used in the manufacture of a special precision coupled micro sized
ball lens. This tiny ball lens is used to focus the high-intensity red laser at the optimum point of the optical fiber core.
Since cheap laser light pens do not use precision-coupling optics, their red lasers are not focused at the correct
point, and thus produce sub-par results. Each unit comes with a protective rubber boot, carrying strap, 9-volt
battery, and CD-ROM with operations manual.

Application #2: Visual Fault Location
The PCVFL can also be used as a troubleshooting tool to determine if there are breaks, micro-bends, or
any other anomalies causing excessive loss within the first few feet of the fiber under test, located in the
splice tray. The laser diode in the PCVFL injects high-intensity red laser light into the near-end connector.
If this light encounters any anomalies, such as a break or a micro-bend, the light is deflected into the fiber
jacket, producing a red glow at the point of the anomaly. Some optical fiber jackets are colored so that it is
difficult to see red light shining through, so it is recommended to keep the room light at a minimum when
using the PCVFL for visual fault location.
Application #1: Port Identification
The PCVFL can help take the guesswork out of
identifying ports in a fiber patch panel or
checking polarity of a duplex connector.
Connect the PCVFL to one end of a fiber link,
and the high-intensity, precision-coupled red
laser diode will allow the user to visually identify
the port by the presence of a red glow emitting
from the connector on the other end. The
PCVFL allows for visual port identification of
fiber optic links up to 5 kilometers (3.1 miles)
