Innovative PMD diagnostics by FiberWork leads to fiber network design & optimization as well as to capex & opex savings
7/2/2004
FiberWork Optical Communications is specialized in developing innovative fiber optic solutions. Its specialized PMD (Polarization Mode Dispersion) diagnostics have helped the main South-American carriers in deploying their high capacity DWDM fiber networks. FiberWork’s "OSPA Optical S-Parameter Analyzer", "FWL Optical Telephone" and "Technical Trainings & Consulting for decision making professionals" are also unique FiberWork solutions.
A fiber network diagnostic is a specialized and innovative service created by FiberWork that goes much further than just field measurements. It comprises detailed field data acquisition and their in-depth analysis by expert PhD professionals. The outcome is a set of recommendations intended towards network design optimization, capex and opex savings, better exploitation of fiber transmission capacities and future-proofing the network. Such information provide an important support for decision making before network design and upgrade as well as for dark fiber valuation, needed for fiber leasing, swap and other frequent telecom market negotiations. It helps both sides of the table to feel more confident, avoiding misleading and promoting fair negotiations.
FiberWork has conducted PMD diagnostics in several thousands of long distance fiber routes. These data has been compiled into a PMD measurement audit, which reveals that 19% of the surveyed fibers present PMD levels higher than 0.5 ps/Ökm. Therefore, they do not comply with requirements of current and future transmission technologies, such as 10Gb/s and 40 Gb/s systems. Also, because higher PMD induces higher bit error rates, which reduces OSNR margins, less DWDM channels can be lit in such high PMD fibers.
