*技术参数说明:NTCF22ABB光纤通信终端设备

NTCF22光通信就是以光波为载波的通信。增加光路带宽的方法有两种:一是提高光纤的单信道传输速率;二是增加单光纤中传输的波长数，即波分复用技术(WDM)。

目前宽带城域网(BMAN)正成为信息化建设的热点，NTCF22 DWDM(密集波分复用)的巨大带宽和传输数据的透明性，无疑是当今光纤应用领域的首选技术。然而，MAN等具有传输距离短、拓扑灵活和接入类型多等特点，如照搬主要用于长途传输的DWDM，必然成本过高;同时早期DWDM对MAN等灵活多样性也难以适应。面对这种低成本城域范围的宽带需求，CWDM(粗波分复用)技术应运而生，并很快成为一种实用性的设备。NTCF22对光通信来说，其技术基本成熟，而业务需求相对不足。以被错为“宽带接入最终目标”的FTTH为例，其实现技术EPON已经完全成熟，但由于普通用户上网需要的带宽不高，使FTH的商用只限于一些试点地区。但是，在2006年，随着IPTV等三重播放业务开展，运营商提供的带宽已经不能满足用户对高清晰电视的要求，随之FTTH的部署也提上了日程。无独有偶，ASON对传输网络控制灵活，可为企业客户提供个性化服务，不少运营商为发展和维系企业客户，不惜重金投资建设ASON.

全光网络未来传输网络的最终目标，是构建全光网络，即在接入网、城域网、骨干网完全实现“光纤传输代替铜线传输”。而目前的一切研发进展，都是“通近”这个目标的过程。

* Technical parameter description :NTCF22ABB optical fiber communication terminal equipment

NTCF22 optical communication is the communication with light wave as the carrier. There are two ways to increase the optical bandwidth: one is to increase the single-channel transmission rate of the optical fiber; The second is to increase the number of wavelengths transmitted in a single fiber, that is, wavelength division multiplexing technology (WDM).

At present, broadband metropolitan area network (BMAN) is becoming a hot spot of information construction, NTCF22 DWDM(Dense wavelength division multiplexing) huge bandwidth and transmission data transparency, is undoubtedly the preferred technology in today's optical fiber application field. However, MAN has the characteristics of short transmission distance, flexible topology and multiple access types. For example, copying DWDM, which is mainly used for long-distance transmission, will inevitably cost too much. At the same time, early DWDM is also difficult to adapt to flexible diversity such as MAN. Faced with the need for broadband in this low-cost metropolitan area, CWDM(coarse wavelength division multiplexing) technology came into being and quickly became a practical device. NTCF22 for optical communication, its technology is basically mature, and the business needs are relatively insufficient. Taking FTTH, which is mistaken as "the ultimate goal of broadband access" as an example, its implementation technology EPON has been fully mature, but due to the low bandwidth required by ordinary users to access the Internet, the commercial use of FTH is limited to some pilot areas. However, in 2006, with the development of triple play services such as IPTV, the bandwidth provided by operators could not meet the requirements of users for high-definition TV, and the deployment of FTTH was also put on the agenda. Coincidentally, ASON has flexible control over the transmission network and can provide personalized services for enterprise customers. Many operators have invested heavily in the construction of ASON in order to develop and maintain enterprise customers.

The ultimate goal of the future transmission network is to build an all-optical network, that is, to fully realize "optical fiber transmission instead of copper wire transmission" in the access network, metropolitan area network and backbone network. All the current research and development progress is the process of "getting close" to this goal.
