光时域反射仪 AQ7280

稳定光源*

光源输出稳定连续光，与光功率计组合使用，用来准确测量点到点的衰减。通过调制光功能，也可以输出 270Hz/1kHz/2kHz的调制光，用于在现场光纤网络中识别光纤或连续性检查。 *将选中的OTDR单元作为选件时适用。

 

可见光源

可见光源是可见、连续/调制的红色激光，是用来检查跳线、发射光纤或短光纤链路连续性的宝贵测量仪器。发 生故障事件时，可以在视觉上将光纤上的断点和弯曲识别为可见光。

AQ7283J

Supports 1383 nm for optical fiber cable inspection
1-port OTDR 1310/1383/1550/1625 nm

• Supports the water-peak wavelength of 1383 nm where water ions (OH) in optical fibers absorb light.
• Suitable for the inspection of optical fiber production and the cabling process of optical fibers.
• Its portability allows the on-site testing of communications network lines when CWDM networks are introduced.

Traditional single-mode fibers (SMF) contain a large amount of water ions (OH). Since water ions (OH) absorb light at 1383 nm, the optical loss of single-mode fibers increases at 1383 nm, this characteristic is known as the water-peak. The AQ7283J was designed with the 1383 nm wavelength capability to specifically test the water-peak in SMF.

AQ7283E

Equipped with “FILTERED” 1625 nm port for live-line maintenance
2-port OTDR 1310/1550 and 1625 nm

• A built-in 1625 nm port with a cut filter to isolate from the communications wavelength enables the measurement of live-lines without being disturbed by active communications signals.
• The wavelength accuracy of 1625 nm ±10 nm is guaranteed to enable maintenance of 10 GE-PON. Whereas other OTDRs with a broader wavelength tolerance could disturb the 10GE-PON transmission signals.
  Note: The AQ7283F is another three-wavelength model with 1310/1550 and filtered 1650 nm.

Measurement of live communications lines
The built in communications wavelength cut filter in a dedicated 1625 nm port enables testing of fiber where live communications traffic wavelengths (1310, 1490, 1550 nm) exist.

Macro bending measurement
The optical transmission loss of optical fibers at long wavelengths like 1625 nm increases at the point where the macro-bending occurs. By comparing OTDR waveforms measured in each wavelength, the macro bending can be detected.
*Other OTDR units with 1625 nm: AQ7283H, AQ7283K, etc.

AQ7282G

Three-wavelength model for FTTH network testing
1-port OTDR 1310/1490/1550 nm

• Successor model of the AQ7275 OTDR (735035)
• Suitable for the installation check of FTTH networks that requires the measurement at 1490 nm.
• More affordable price than the AQ7283K that is a four-wavelength model with 1310/1490/1550/1625 nm.
