1.1.1 The TOP Optica! LED Source
The Tektronix TOPI 30 Dual-Wavelength (850/1300nm)
Optical LED Source is a small, rugged handheld
instrument for use in installing and testing attenuation of
both singlemode and multimode fiber optic links, including
telephony, datacom, CATV, FDD I and LAN applications.
The instrument provides two calibrated outputs at 850nm
and 1300nm to speed up transmission loss measurements.
Providing both CW and MODulated outputs, the user can
internally set the modulation frequency to match the
frequency signatures (270/1000/2000Hz) required by fiber
identifiers and signal tracers.
The palm-sized TOPI30 provides the flexibility in a single
unit to interface to all industry standard fiber-optic
connectors with high throughput, repeatability and stability.
This optical interface of this instrument features the
precision snap-on connector (SOC) interface. A wide range
of push-pull SOC adapters are available covering all
popular industry-standard fiber-optic connectors (including
FC, ST, SC, SMA, E2000, DIAMOND, etc.).
The TOP series LED source is powered by two common
AA alkaline batteries which provide over 20 hours of
portable life. The front panel Status LED blinks when the
batteries are low. Together with the TOP200 optical power
meter, the fiber optic technician possesses the smallest,
high-performance fiber optic test set in its class.
