NOYES OFI-400 Optical Fiber Identifiers are designed to detect and measure 1 the core power levels of optical signals on singlemode optical fiber without disconnecting or cutting the fiber. These instruments are simply clamped onto a fiber and indicate the presence and direction of traffic, continuous test signals and modulated test tones. This permits network personnel to easily and quickly identify a specific fiber without risk of revenue service disruption. The OLS7, OLS2, CSS1-SM and CSS1-MM  series of optical light sources are ideal companions for the OFI-400 optical fiber identifiers.

No Adapters to Purchase, Store, Swap, or Misplace.
The OFI-400 uses a unique optical head design featuring a two-position plunger that enables it to be used with 250 µm, 900 µm and ribbon fiber or 2 mm and 3 mm jacketed fiber. Other brands of optical fiber identifiers require users to purchase, store and swap out optical plungers each time a different type of fiber is tested. The OFI-400 optical head induces a safe, repeatable macro-bend to the fiber that allows a small amount of light to escape for analysis. The insertion loss induced by the macro-bend is too small to affect the signal on the fiber and the integrity of the fiber is unaffected by the measurement process.

OFI-400 instruments are designed to be simple, easy- to-use and reliable. Each features an ergonomically designed macro-bend trigger that is comfortable to use. An integrated, backlit LCD display allows OFI-400s to be used in dimly lit spaces. Powered by 1.5 V AAA batteries, the OFI-400 can make thousands of fiber tests before repalcing batteries.

OFI-400
The OFI-400 is designed for use with a wide range of single-mode fibers including 250  μm (bare) coated, 900 µm buffered and ribbon fibers or 2 mm and 3 mm jacketed fibers. The OFI-400 is ideal for network personnel involved in installation, reconfiguration, restoration and maintenance tasks that involve bare, buffered, jacketed or ribbon fibers in outside plant pedestals, fiber cabinets, aerial
enclosures and inside plant premises demarcation cabinets. The slim design of the OFI-400 head facilitates access in crowded splice trays.

OFI-400C
Designed specifically for use with 2 mm or 3 mm jacketed single-mode fibers, the OFI-400C is ideal for general purpose maintenance, configuration and installation tasks. The OFI-400C is functionally equivalent to the OFI-400 but includes an optical head design and a calibration scheme optimized for use with jacketed fiber.

OFI-400HP
The OFI-400HP is designed for use where high levels of optical power are present. This includes fibers carrying a single high-power signal, CWDM or DWDM signals with high total power levels, amplified optical signals, or pump lasers associated with EDFA or Raman amplifiers. When display reaches +23 dBm (200 mW) or greater, the OFI-400HP will display “High” warning indication.
