《同調光網絡的時代》白皮書概述了相干光技術和其所解決的關鍵功耗、成本和光網絡挑戰，支持電信營運商以極低的資本和營運成本來提供大量的高容量服務。PMC-Sierra POLO 40G SoC讓在城域、區域和長距光網絡中大規模部署同調40Gb/s成為可能，與使用非同調（non-coherent）40G技術相比，這種先進的SoC架構增加了一倍的線卡密度，能減低功耗超過50%。POLO 40G可幫助電信營運商利用現有光纖網絡設施來支持40Gb/s帶寬以應付迅猛增長的視頻和無線數據流量，從而降低資本和營運支出。

The Era of Coherent Optical Networking

Coherent Technology dramatically increases the quantity of transmission data by increasing the spectral efficiency of that transmission. The same advanced Digital Signal Processing (DSP) technology that enables this capacity increase also eliminates an entire class of equipment Service Providers have had to deploy. Coherent Technology reduces Service Provider CAPEX and OPEX by eliminating optical impairment compensation equipment and the extensive optical link engineering manpower required to maintain that infrastructure.

PMC-Sierra's Coherent technology is the key building block to enable the mass deployment of Coherent optical technology first in Service Provider Long Haul/Regional networks and later Metro networks. 下載白皮書，請訪問http://www.pmc-sierra.com/whitepaper-processor-mips-sonet-ethernet/。
