OPM 4 Optical Power Meter
The OPM 4 optical power meter may be used to measure optical power in Premises, Telco, or Broadband fiber optic networks. When used with an LED or Laser light source, the OPM 4 also measures insertion loss of multimode or single-mode cables. The OPM 4 offers Wave ID, automatic wavelength identification and switching, when used with the OLS 1 Dual or OLS 2 Dual or OLS 4 with Wave ID feature. Multiple test Tone detection is provided for fiber identification. The OPM 4 stores optical references for each calibrated wavelength. An easy to read Dual Wavelength LCD display with Backlight shows measured power [dBm or µW] or insertion loss [dB], calibrated wavelengths, tone signal [Hz], wavelength ID, and the battery charge status. In addition to being powered by two AA alkaline, the OPM 4 can be powered by optional AC adapter and/or rechargeable NiMH battery pack. The OPM 4 optical input port accepts Noyes thread-on style adapter caps. Adapter caps are required for operation and must be ordered separately. The OPM 4 is fully N.I.S.T. traceable.

The OLS2-Dual laser source is a cost-effective, rugged, handheld instrument designed for performing insertion loss measurements on single-mode fiber optic links when used with an optical power meter. When paired with an optical fiber identifier, the OLS2-Dual may be
used for fiber identification. The LASER output is stabilized to ensure accurate test results per current TIA/EIA requirements.
The OLS2-Dual features 1310 nm and 1550 nm (or 1550 nm and 1625 nm) LASER output from a single output port and is easy to operate. This light source offers 4 modes of operation: Dual wavelengths sending ID, single wavelength sending ID, CW, and modulated Tone. [Active Output], [Tone], [Battery], and [External Power] indicators identify the currently enabled operating mode, battery charge status, and external power presence.
The OLS2-Dual output port is equipped with a UCI based removable adapter to allow the output connector to be inspected and cleaned.
In addition to being powered by two AA alkaline batteries, the OLS2-Dual can be powered by optional AC adapter and/or rechargeable NiMH battery pack. The OLS2-Dual is fully N.I.S.T. traceable.

• Cost-effective, easy to use
• N.I.S.T. Traceable
• The OLS2-Dual may be substituted for terminal equipment in the central office or head end to provide a stable output for loss measurements.
• For single-mode applications, such as Telecom or CATV, the OLS2-Dual may be coupled with an optical power meter as a test kit to perform optical loss tests at 1310 and 1550 nm.
• In the modulation Tone mode, the OLS2-Dual generates a Tone signal into the fiber. This signal is detected by the OFI-200, optical fiber identifier, to isolate specific fibers in a bundle prior to splicing or rerouting.

Noyes OFI 200B Optical Fiber Identifier
Noyes Optical Fiber Identifiers are rugged, handheld, and easy-to-use fiber optic test instruments designed to detect optical signals transmitted through a single-mode fiber without disrupting traffic. During installation, maintenance, rerouting, or restoration; it is often necessary to isolate a specific fiber. By simply clamping an Optical Fiber Identifier onto a gently bent fiber, the unit will indicate if there is [No Signal], [Tone], or [Traffic] and identify signal direction.
The OFI 200 model Identifier is equipped with a unique two-position head design that can be configured to work with 250 µm, 900 µm, ribbon, or jacketed fiber in seconds, without tools or adjustments. When testing coated fibers, the slim design of the OFI 200 model allows easier access on a splice tray where the amount of work space is limited. The clamping trigger is ergonomically designed to fit the natural motion of the operator’s hand. A high impact molded plastic case makes the OFI 200 model suitable for use outside plant or in the central office.
The OFI 200 model Identifier is battery operated with the battery indication feature and performs thousands of tests before batteries replacement is necessary.

OFS 300-200C Optical Fiber Scope
The OFS 300 is a versatile instrument for the inspection of optical fiber connectors. By employing a universal adapter mount, the OFS 300 offers the ability to inspect virtually any connector style for scratches, dirt, or other problems normally associated with poor transmission performance.
The OFS 300-200C offers precision 200x magnification to easily inspect both multimode and single-mode fiber optic connectors.
The OFS 300 offers 60 hours of continuous battery life. A low battery indicator will flash when approximately 8 hours of optimum brightness remains reducing the risk of eye strain. Various adapter caps are available to convert the mount to the desired connector style. The OFS 300-200C uses the same common threaded connector adapter caps as the Noyes Optical Power Meters and Loss Test Sets.
