plc光分路器封装设备<br /> 5月11日的电信PLC测试选型非常令人关注，很多器件厂商到现场观摩电信PLC测试选型抽签仪式。对于电信指定使用PLC来建设FTTx，不再使用FBT产品，很多行内人士存在不能接受； <br /> 很明显，国人已经掌握了FBT 80%的产品制造技术，特别是一些公司（例如朗光科技等）拥有完全的自主知识产权，并且产品大量出口海外。而PLC关键技术、封装设备、关键元件几乎都被国外所垄断，国内企业仅仅只是代工厂的地位。<br /> 所以很多人都反应，FBT是不折不扣的民族产业，况且在国外FTTx建设过程中，1*2，1*4，1*8的分路器一般倾向于使用coupler，因为coupler目前在这几款产品上相较于PLC有成本优势，更贴近实用。PLC目前无论在技术，生产，价格，还是利润空间，在1*2，1*4，1*8三种规格上并不具有什么优势。所以作为主流coupler生产厂家来说，电信这种一棍子打死的行为值得商榷。 <br /> “一个连芯片都生产不了的产品，竟然取代了国有化很高的产品，成为电信唯一指定使用产品，在一定程度上，打击了广大民族企业家的信心，也使得相当大利润被国外企业所剥夺，实在是个得不偿失的决策。PLC技术在欧美广泛使用，更多原因还是PLC技术源自欧美。 ”<br /> 据我们了解，目前PLC器件中的芯片、胶水以及调芯封装设备等大都需要进口，国内绝大部分PLC企业集中在封装端，国内在波导芯片的国产化方面进展非常缓慢。根据行内机构调查，目前对PLC Splitter芯片进行研发的企业和科研机构屈指可数，国产芯片的性能和可靠性仍与国外产品存在一定差异，大部分厂商仍选择进口芯片；<br /> 国内目前不可能做芯片。这不是技术问题，而是市场规模问题。<br /> 即使国内有厂商推出自主芯片，由于产量有限，市场规模较小，仍无法养活企业生存。除此之外，高昂的设备维护费用也会让企业望而却步。目前光波导芯片大部分从韩国、欧洲和北美进口，我们熟知的有韩国Woorio，丹麦的NKF，法国的Teem等，这些厂商还有其他主营业务，并非单有波导芯片，“总体来说，客户很分散，市场很分散，除非你能掌握所有封装客户，否则单靠芯片业务无法存活，这也是国内迟迟无法出现波导厂商的主要原因。<br /> 不过随着光通信行业的不断火爆，也有一些国内企业生产出来自己的波导芯片，例如四川的飞扬科技；<br /> 另一方面调芯封装设备等大都需要进口，前在大多是生产线上的封装设备都采用进口产品；例如日本骏河精机、NEWPORT、THORLABS 、日本神津产品为什么我们国内的光学企业不能替代他们的产品呢？众所周知中国在光学调整架行业有广大的生产基础，这方面的能力是非常强悍的，随着分路器生产数量的增加，竞争必然更加激烈，在工艺、技术攻关已经相当成熟的企业，购买国产PLC光分路器-封装设备必然是一个不错的选择；是扩大产能降低运营成本，国产化产业链的必然趋势；另一方面也是给民族企业一次机遇。所以我们微纳光科在2009年开始代理日本骏河精机的PLC光分路器的封装系统，并且努力实现国产化！实现与器件生产商双赢的契机。<br /> 2010年7月，国产化的PLC封装系统已经被微纳光科制造出来了，产品性能通过商业测试，完全可以商用。所有希望广大器件生产厂家更多关注民族产业，优先选择国产封装系统。<br /> </div> <div class="postmsg">如果有朋友关注<br /> 微纳光科 提供PLC光分路器封装解决方案，生产的器件确认合格.设备才算验收完毕！<br /> 国产化节约成本，负责生产培训。<br
