Fluke FOS-850/1300 Fiber Optic Light Source

Description

Trace multimode fiber optic cable attenuation and loss margins across commercial data centers by powering on the Fluke Fiber Optic Light Source. This handheld optical source emits calibrated 850 nm and 1300 nm light waves. It generates infrared laser energy, demanding that technicians never stare directly into optical output ports during network cable testing.

High-impact composite thermoplastic constructs the handheld meter case, fitted with an integrated protective elastomer shock boot and ST optical output port. Solid-state LED light-emitting diode circuits run on a standard nine-volt alkaline battery, delivering twenty-four hours of continuous optical power. Total dry tool weight measures 0.8 lbs with battery installed. Dimensions measure 7.5 inches long, 3.5 inches wide, and 1.5 inches deep for tool pouch carry.

Key Features of Fluke FOS-850-1300

Network data technicians buy Fluke FOS-850-1300 optical sources to verify loss budgets and test multimode fiber optic links alongside optical power meters. Equipment pricing delivers dual-wavelength LED optical output and rugged field portability for commercial telecommunications infrastructure testing.

• Dual-wavelength optical LED outputs transmit calibrated 850 nm and 1300 nm infrared light down multimode fiber.
• Stabilized light emission circuits hold optical output power within 0.1 dB drift over continuous testing runs.
• Standard ST optical connector ports interface with commercial patch cords and fiber distribution panels.
• Continuous wave and modulated 2 kHz pulse modes allow optical fiber tracing through active cable bundles.
• Protective rubber holsters absorb drops onto concrete data center floors and protect optical port ferrules.
• Battery life indicators signal voltage drops to ensure optical power output remains within calibrated tolerances.
• Compact pocket-sized chassis dimensions allow single-hand operation while patching jumpers inside fiber racks.

Optical Power Drift Bench Metrics

Optical bench testing with a calibrated laboratory power meter confirms output power holding at minus twenty dBm into 62.5/125-micron multimode fiber. Optical power stability holds within 0.05 dB drift across one hour of continuous transmission after five minutes of warm-up. Center wavelength spectral testing measures 850 nm plus or minus thirty nanometers and 1300 nm plus or minus thirty nanometers. Battery circuit monitoring confirms stable optical output down to seven volts battery cutoff. Operating sound meter tests record zero decibels.

Fiber Testing Usability Realities Maintenance

Holding this 0.8 lb optical source in one hand allows fast wavelength toggling using the top slide switch while inserting ST patch cords. Protective dust caps protect internal optical ferrules between test passes. Do not buy this multimode LED source for single-mode fiber networks over 1310/1550 nm, OTDR backscatter testing, or visual red-light fault finding.

• Clean the optical connector ferrule using lint-free fiber wipes and pure reagent alcohol before every connection.
• Keep protective rubber dust caps threaded over optical ports whenever patch cables are disconnected.
• Replace the nine-volt alkaline battery whenever the low battery LED illuminates on the front panel.
