Wandel & Goltermann OSA-155 DWDM System Analyzer
Spectrum and WDM parameter analysis in range 1450 nm to 1650 nm for applications on DWDM systems.
The OSA-155 DWDM System Analyzer is a field-ready optical spectrum analyzer offering measurements of wavelength, power and optical SNR on the different carriers of multiwavelength signals in the range 1500 to 1620 nm with up to 50 GHz/0.4 nm spacing. With a maximum channel power of +15 dBm, up to 32 channels can be measured and displayed in a WDM table list. More than 32 channels (up to 256) can be measured simultaneously with reduced channel power. In the extended wavelength range 1450 to 1650 nm, measurements of the optical supervisory channels (OSC) are possible.

Measured results are presented either as complete spectral analysis graphics or as a WDM table, listing all DWDM carriers with their relevant parameters. The measured results are displayed on a large 10.4@ TFT color LCD with touchscreen capability. Because the instrument is intended for field service during installation, maintenance and troubleshooting, mechanical ruggedness and battery operation were important considerations in the design of the instrument. The weight of the instrument does not exceed 9 kg/19.6 lb including the battery.

Interfaces are provided for output of measured results to an external printer (V.24/RS-232 serial and Centronics parallel) and for remote operation, diagnosis and monitoring via modem or LAN (TCP/IP). In conjunction with the CATS Test Case library, remote control via V.24/ RS-232 or IEEE 488/IEC 625 becomes fully automatic.

Test engineering for field operations
Besides being powered from the normal AC line, the OSA-155 can also run intermittently for up to four hours from batteries. The batteries are rechargeable and easily replaced. It is also possible to supply power from an automobile battery via the DC input. This feature is very useful when the instrument is part of a monitoring or surveillance system, since the OSA-155 automatically switches to battery power if the AC power supply fails. Even when fitted with batteries, the OSA-155 only weighs about 9 kg, so it is a truly portable device. The optical module is particularly insensitive to knocks and vibration, making it ideal for field operations.


Features:

  • Analyzer for DWDM systems with channel spacings of 50 GHz/0.4 nm and higher
  • Fast and complete DWDM system analysis based on accurate wavelength, power and S/N ratio measurements

  • Easy carrier power alignment and troubleshooting through spectral analysis
  • Wide input power range enables high channel power applications
  • Remote operation/testing via modem or LAN (TCP/IP)
  • Ideal for DWDM system installation, maintenance & troubleshooting: rugged and portable (9 kg/19.6 lb)
  • Comprehensive instrument powering: internal battery, external battery connection and AC line
  • Easy and intuitive touchscreen operation
  • Integration into monitoring/surveillance systems
  • Interchangeable adapter system for interconnectivity with all common optical connectors
