Noyes Noyes OFI-200 Handheld Optical Fiber Identifier Noyes Fiber Systems
NOYES Optical Fiber Identifiers are rugged, hand-held, 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 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 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 suitable for use outside plant or in the central office. The OFI-200 is battery operated with a battery indication feature and performs thousands of tests before battery replacement is necessary. Features • Rugged, hand-held, lightweight • • Accepts 250 µm, 900 µm coated fiber, 3 mm jacketed fiber cable and ribbon fiber • • No head swapping or adjustments • • Identifies light carrying fiber and indicates direction of traffic • • Low insertion loss, traffic remains uninterrupted • • Indicates Tone signal visually and audibly • • 2 kHz Tone detection • • Low battery indication •

Ideal IDEAL 61-737 400Amp 600V AC/DC Digital TRMS Clamp Meter with NCV and Temp Audible Alert
The IDEAL 61-737 clamp Meter is a CAT III auto ranging true root mean square (TRMS) digital clamp meter that measures up to 400 Amp AC via the clamp head. It measures up to 600-Volt AC and DC, frequency, resistance, continuity, capacitance, and diodes via test-leads (included) and measures temperature (F/C) via a K-Type thermocouple (included). It's capable of detecting the presence of voltage between 40-Volt to 600-Volt via a non-contact sensor in the right tip of the clamp. The large display can be backlit when working in poor or zero lighting conditions. The unit uses an illuminated red LED in the center of the meter and emits audible tones to notify when voltage is above 30-Volt, when continuity is detected and when the NCV senses voltage within its set range. The clamp head has a built-in probe tip holder on the backside of the right clamp to allow measurements holding the clamp in 1 hand and the second lead in the other hand. The meter has a hanging strap mount (compatible with all other IDEAL meters with this feature) that allows for a hanging strap (sold separately) to be attached to the meter so it can be hung from a nail, screw or magnetic surface.
