《同調(diào)光網(wǎng)絡(luò)的時(shí)代》白皮書概述了相干光技術(shù)和其所解決的關(guān)鍵功耗、成本和光網(wǎng)絡(luò)挑戰(zhàn)，支持電信營運(yùn)商以極低的資本和營運(yùn)成本來提供大量的高容量服務(wù)。PMC-Sierra POLO 40G SoC讓在城域、區(qū)域和長距光網(wǎng)絡(luò)中大規(guī)模部署同調(diào)40Gb/s成為可能，與使用非同調(diào)（non-coherent）40G技術(shù)相比，這種先進(jìn)的SoC架構(gòu)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(yùn)商利用現(xiàn)有光纖網(wǎng)絡(luò)設(shè)施來支持40Gb/s帶寬以應(yīng)付迅猛增長的視頻和無線數(shù)據(jù)流量，從而降低資本和營運(yùn)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?jiān)L問http://www.pmc-sierra.com/whitepaper-processor-mips-sonet-ethernet/。
