ACTERNA has announced the availability of its OSA-160/200 optical spectrum analysers with new options for polarisation mode dispersion (PMD) measurement and optical component testing such as side mode suppression ratio (SMSR) laser qualification.
Compact, lightweight, robust and easy to use, OSA-160 (single port) and OSA-200 (dual port) are suitable for field teams involved in DWDM system installation and trouble shooting.
Covering wavelength bands from 1280nm to 1650nm (O, S, C and L), and featuring very fast measurement speeds of just 2.5s per full fibre scan, the additional functionalities of the OSA units empower customers to employ a highly cost-effective and stand-alone solution for their optical network testing.
OSA-200 was the first dual-port analyser available in the market. Its capacity to test two independent WDM channels simultaneously allows field teams/technicians to qualify optical components such as EDFAs while they are in-service.
Input and output signals are measured automatically and, with new calculation software built-in to the OSA-200, the entire test process can now be carried out at the touch of one button, saving significant test time in the field and analysis time in the office.
PMD is an increasingly important measurement in high speed networks where it can become the critical limiting factor to medium link lengths.
The new PMD option for OSA-160 and OSA-200 offers an economic, integrated measurement capability, eliminating the need for additional equipment, apart from the requisite light source and polariser.
This complete option saves time in the field where other solutions require hardware modules changes or additional measurement instrumentation.
Also new to the OSA-160/-200 is SMSR for laser qualification which is now available as an option with both models.
OSA-160 and OSA-200 feature a 'wavelength drop' option, enabling the technician to 'filter' individual DWDM channels for further analysis using BERT or Q-factor, for example.
This reduces cost and means field teams do not have to carry extra instrumentation for this application.
