The white card of the open network is blowing to the fiber-optic broadband network. The international organization Broadband Forum (BBF) and the Open Network Foundation (ONF) actively promote the "Open Broadband". The ONF is composed of cross-network and telecommunications companies such as Google and Deutsche Telekom.BBF actively advocates the open broadband architecture, and ONF promotes the certification program. Ten products in the world have passed the open broadband verification, and Taiwanese manufacturers have won seven of them. The results are outstanding, including Edgecore's three telecom switches and two bureaus. Terminal equipment (OLT), Zhonglei's customer premises equipment (ONU) and Zyxel's OLT, as for Wiwynn, also actively participate in the ONF open broadband plan.Netcom Factory said that in the past, the optical fiber market from OLT to ONU was a complete set of shipments from major manufacturers. With the boom of open network, broadband was blown. 5G open network O-RAN plus open broadband, the overall network benefit is the greatest, coupled with optical fiber technology Entering the era of 10G PON, dismantling the optical fiber network in an open source way will form a white-brand business opportunity for new telecom switches, OLTs and ONUs.
