In recent years there have been increasing deployments of fiber to the home
(FTTH) service in access network areas, along with advances intransmission
technologies such as B-PON, G-PON, and GE-PON. Inaddition, there have been
important advances in CWDM transmissiontechnology, which is expected to be
used in metropolitan areas. As networkshave evolved, there has been an
increasing need for high price-performancemeasuring instruments capable
of high-throughput evaluation of the opticalcharacteristics of optical devices
and components used in these facilities. The AQ2200-136 TLS module is an
optional wideband variable wavelengthlight source designed for the AQ2200
multi-application test system. Althoughit is lightweight with a small,
2-slot module, it is capable of tuning range the 1440 nm to 1640 nm. |

1. Swept measurement synchronized with optical spectrum analyzer
(standard function)
The AQ2200-136 can perform synchronized swept measurements
* when combined with Yokogawa’s AQ6317B/C
optical spectral analyzer. This combination enables high-dynamic-range
measurements, with features such as a band elimination filter (BEF).
* Synchronized swept
measurement: This function performs wavelength swept measurement
while synchronizing thewavelength measured by the optical spectral
analyzer to the wavelength output by the variable wavelength
lightsource, without using an external controller PC.
Measurement time: Approximately 22 seconds (typical value;
obtained with the AQ6317B/C level range set to AUTO, Span set to
20 nm, and measurement points set to 1001)
2. Swept measurement system (standard function)
The AQ2200-136 can be combined with the AQ2200-211 sensor module
or AQ2200-231optical sensor head* to
perform high-speed, wideband wavelength swept measurementswithout
using a controller PC.
* The AQ2200-201
interface module is required in order to use the AQ2200-231.
The AQ2200-136 can be used to measure a variety of optical devices
and components.Example applications include:
- Measurement of the insertion loss and wavelength dependence of optical filters
- Measurement of the wavelength dependence of optical couplers and optical attenuators
- Measurement of passed center wavelength and pass band flatness of CWDM mux/demux
High-resolution measurement with 20,000 data points (maximum)
and 1 pm wavelengthresolution (minimum)
Measurement time:
Approximately 11 seconds with level range set to Hold
(typical value; obtained with AQ2200-136 and
AQ2201 set to 1440 to 1640 nm wavelength range,0.1 nm-step sweeping
width, and 2000 data points)
Approximately 13 seconds with level range set to Auto2
(typical value; obtained with AQ2200-136 and
AQ2201 set to 1440 to 1640 nm wavelength range, 0.1 nm-step sweeping
width, and 2000 data points)
