Yokogawa AQ4270-01 Hand Held LD Light Source

Overview
Excellent cost performance instrument in a compact package. The AQ4270-01 LD light source is one-third the size of previous LD light sources even though it provides output on two wavelengths. With a cleanable universal adapter, the AQ4270-01 is easy to maintain, and is rugged and durable. This handheld light source can be used with confidence even when working outside on fiber-optic installation and maintenance.

AQ4270-01 Hand Held LD Light Source

Functions

The cleanable universal adapter makes the AQ4270-01 easier to maintain.
The service life of the ferrule edge, which can easily damage during field work, has been greatly improved, helping to reduce maintenance costs. (even if it is damaged, it is possible to replace just the connector unit at low cost).
Low-power consumption design allows approximately 24 hours of battery life at normal temperatures (using two alkaline dry cells).
The AQ4270-01 is the ideal light source for use in fiber-optic installation and maintenance.
Excellent output stability:-
Wavelength: 1310/1550nm ±20nm.
Stability: 1dBpp or less (temperature stability)
±0.05dB or less (time stability).
CHOP light output capability (frequencies: 270Hz, 1kHz, 2kHz;
frequency precision: ±0.15%).
