Information on calibration

We accept calibration work for our products and issue a “calibration certificate”.
If adjustment is necessary, we will adjust it.
Also, if a defect (repair required) is confirmed, repair + calibration is also possible.
Optical power meters , light sources , light source units for · 215 205A , in has been accepted calibration.
(We also accept proofreading of products other than the current product. For now, up to about 20 years ago)
Contact Us or until the dealer.

※ Please send only the main unit as much as possible. (To prevent loss of accessories)

"Calibration" is …

This is to prove the normal operation of your measuring instrument.
If the instrument doesn’t display the correct measured value, you can’t use it.
At our company, the accuracy is maintained by conducting a trace with the national standard regularly at the Japan Quality Assurance Organization (JQA), which is an official calibration organization once a year.
We calibrate the regular standard with a JQA calibrated intermediary (temporary standard), and use this regular standard to measure in fields such as development, manufacturing, and inspection.
This standard device is used to prove the normal operation of your equipment. (Proof certificate issued)
It is recommended that calibration be performed once a year.
The period of storage is usually about 1 week to 10 days.
Inquiry of calibration, etc. phone · FAX · E-mail I have heard.
Please fill out the form below and apply.

Fiber measurement method

Basic optical fiber measurement method (mini series)

STEP①

ファイバーの測定方法1e

1.  Connect the reference fiber from the light source to the optical power meter as shown in Fig. 1,

  and display the output from the light source on the optical power meter.

  Let this displayed value be P1.

  (P1: Displayed value of optical power meter when only reference fiber is connected)

  Figure 1 , Example : P1 = -5dBm

STEP②

ファイバーの測定方法2e

2.  Disconnect the reference fiber and the optical power meter from the connection in Fig. 1,

  and connect the fiber to be measured via the relay adapter to the disconnected section as shown in Fig. 2.

  At this time, the output of the light source via the reference fiber and the measured fiber is displayed on the optical power meter.

  Let this displayed value be P2.

  (P2: Optical power meter display value when the reference fiber and the measured fiber are connected)

  Figure 2 Example: P2 = -7.5dBm

STEP③

3.  The difference between the optical power meter readings of P1 and P2 is the attenuation (loss) of the measured fiber.

  Calculation formula: P2-P1 = loss of the measured fiber

  [ Example: -7.5dBm – ( -5dBm ) = -2.5dB ]

Supplement

(1) From the light source output when the reference fiber is connected, how much output has dropped by connecting the fiber to be measured. The amount of this drop is the attenuation of the fiber to be measured.

(2) Our power meter has a “relative value measurement function”. (Excluding 216 for current products)

This series of “P2-P1 = loss of fiber under test” can be simplified.

After measuring the reference fiber, press the REL (dB) switch to set the reference value, and then connect the measured fiber, the attenuation of the measured fiber can be displayed automatically.

The actual procedure:

Connect as shown in Fig.1 and measure → press REL (dB) → remove power meter.

Connect the measured fiber to the removed section via a relay adapter as shown in Fig. 2.

Basic Optical Fiber Measurement Method (Handy Series)

STEP①

ファイバーの測定方法3e

1.  Connect the reference fiber from the light source to the optical power meter as shown in Fig. 3,

   and display the output from the light source on the optical power meter. Let this displayed value be P1.

   (P1: Displayed value of optical power meter when only reference fiber is connected)

   Figure 3 Example: P1 = -25dBm

STEP②

ファイバーの測定方法4e

2.  Disconnect the reference fiber and the power meter on the sensor side from the connection in Fig. 3, and connect the fiber to be

         measured via the relay adapter to the disconnected section as shown in Fig. 4. At this time, the output of the light source

         via the reference fiber and the measured fiber is displayed on the power meter on the sensor side. Let this displayed value be P2.

         (P2: Optical power meter display value when the reference fiber and the measured fiber are connected)

         Figure 4 Example: P2 = -27.5dBm

STEP③

3.  The difference between the optical power meter readings of P1 and P2 is the attenuation (loss) of the measured fiber.

  Calculation formula: P2-P1 = loss of the measured fiber

  [ Example: -27.5dBm – ( -25dBm ) = -2.5dB ]

Supplement

(1) From the light source output when the reference fiber is connected, how much output has dropped by connecting the fiber to be measured. The amount of this drop is the attenuation of the fiber to be measured.

(2) Our power meter has a “relative value measurement function”.

This series of “P2-P1 = loss of fiber under test” can be simplified.

After measuring the reference fiber, press the REL (dB) switch to set the reference value, and then connect the measured fiber, the attenuation of the measured fiber can be displayed automatically.

The actual procedure:

Connect as shown in Fig. 3 and measure → press REL (dB) → remove the power meter on the sensor side.

Connect the measured fiber to the removed section via the relay adapter as shown in Fig. 4.

This displays the attenuation of the measured fiber.
