Измерители оптической мощности серии 6334

6334 optical power meter is a powerful optical measuring instrument of high intelligence, high
precision, high sensitivity. It can perform optical power measure with high accuracy and wide
dynamic-range, optical loss and optical stability measure with high resolution. It provides GPIB and RS232 interface ports, can constitute an automatic test system.
6334 optical power meter is widely applied in all optical power measurements such as optical
fiber loss measurement and optical device performance evaluation.it have the characteristics such as wide measuring range, high accuracy, high performance-cost rate, high dependability and easy operation etc.
6334 optical power meter is available in various configurations for the best possible match to
the most common applications. It is a series divided into the five kinds including 6334A、6334B, 6334C, 6334D, 6334E.

Mainly features:

• Zero function
• Auto-range, Hold-range, Manual-range function
• Compensating wavelength response function
• Data storage, recall, output function
• Light division ratio and light division loss test function (only for 6334B、6334C)
• Parameter setting function
• Application function
• GPIB and RS232 interface function

● Zero function
6334 offers zero function. The function is for eliminating the equivalent power that the dark
current and noise of the light detector produce. Measuring faint optical power (absolute optical
power is less than –50dBm), the instrument should be zeroed. Zero must be in the condition of
keeping out the light. It is helpful to improve the measure accuracy.
● Auto-range, Hold-range, Manual-range function
6334 offers auto-range, hold-range, manual-range function. According to light power variety
scope and variety speed, you can adopt the different range mode. For example, if the variety scope of the input light power lack 10 dB, you can consumedly increase the measure speed by selecting the hold-range function, because of it can save consumed time of range switch in auto-range mode.
● Compensating wavelength response function
In order to measure the power in the whole wave-band, 6334 offers an embedded compensating curve agree with the detector’s wavelength response. Moreover, according to the customer's special request, 6334 offers the accurate calibration at some special wavelength.
● Data storage, recall, output function
6334 offers data storage, recall, output function. It is convenient to handle these measure data in the evening period.
● Light division ratio and light division loss test function
6334B, 6334C specially offers light division ratio and light division loss test function, and very
much suits to monitor the power division and loss in the process to manufacture the optical passive device (optical coupler etc).
● Parameter setting function
6334 offers parameter setting function, such as λ(the customer definition wavelength)、
REF(reference power)、CAL(customer calibration factor)、GPIB(GPIB address)、CPLR(light
division ratio), CLOCK(system clock),etc. You can set these parameters according to the demands.
● Application function
6334 specially offers application function, such as extremum MAX(maximum positive
deviation), MIN(minimum negative deviation), DIF(the difference between MAX and MIN),can be used to measure the stability of the optical power.
● GPIB and RS232 interface function
6334 offers the GPIB and RS232 interface. From the RS232 interface, It can output the
real-time measure result. With the GPIB interface, It can constitute the automatic test system with other GPIB equipment and PC.

Typical application
Typical application 1：Measure the size and stability of the light source's output optical power
with 6334.

Connect the output port of the light source and the input port of the optical power meter with
fiber, power on and preheat the instrument, set operation wavelength of the power meter
corresponding to light source’s center wavelength, the measure value is the size of the light source’s output power.
According to the test request, choose and run a function from the MAX, MIN, DIF test
functions, at the same time, the system clock start to time for zero.6334 can automatically execute measure and record the value in the limited time, when the test stop, the measure value is the stability of the light source's output optical power.

Typical application 2：Measure the light division ratio of the optical coupler with 6334.

Connect the output port of the light source and the input port of the optical coupler with fiber,
connect the two output ports of the optical coupler and the two input ports of the optical power
meter(6334B or 6334C) respectively with fiber, press the “mode ” key, the instrument goes into the coupling ratio measure mode, the measure value is the light division ratio and total light division loss.The special function very much suit to monitor the power division and loss in the process to manufacture the optical passive device (optical coupler etc).
