国外运营商 20Gbps 对等光纤宽带用的是 FTTH 不是 FTTR !

Spain: Nokia delivers 20Gbps FTTH | Advanced Television

Nokia has announced that Telefónica Spain has successfully trialled 25G PON technology. The trial, the first in Spain to demonstrate symmetric speeds of 20 Gbps, showed that 25G PON can co-exist with Telefónica’s existing GPON solution.

Telefónica, with almost 60 million FTTH homes passed already deployed in their multiple business units, says it can now get the network ready for future applications such as the Metaverse.

Gonzalo Garzón, Head of Fixed Access at Telefónica España at Telefonica’s, said: “Telefonica was the first operator in Spain to provide gigabit connectivity, but we are not stopping there. Consumer bandwidth demands never halts and exciting applications, like VR gaming, will always be evolved to make the most of available bandwidth. New FTTH technologies give us even more opportunities than home connectivity. With their massive uptick in capacity we’ll be able to offer new business services on the same network.”

Bjorn Capens, VP Europe, Nokia Fixed Networks, added: “Thanks to our Quillion chipset, this 25G PON proof of concept with Telefonica has demonstrated that the huge bandwidth-capacity can be easily added to their existing networks, co-existing with their existing PON technologies. This means customers on the same fibre line can be served with GPON, XGS-PON or 25G GPON, making it much easier to manage upgrade cycles.”

Dependent on the optics chosen, 25G PON supports symmetrical bitrates (25Gb/s in downstream and 25G in upstream) and asymmetrical bitrates (25/10). Though usually located in telecom central offices, Nokia’s high-capacity access nodes are deployed for huge fibre roll-outs. At the start of January, Nokia upgraded VodafoneZiggo’s IP interconnect network in The Netherlands, by putting 7750 Service Routers (SR) into 350 sites. It means the 350-location network can pipe terabytes of comms and entertainment services delivered to VodafoneZiggo’s consumer and business customers.

诺基亚宣布,西班牙电信已成功试用 25G PON 技术。该试验是西班牙首次展示 20 Gbps 对称速度的试验,表明 25G PON 可以与 Telefónica 现有的 GPON 解决方案共存。

Telefónica 的多个业务部门已经部署了近 6000 万户 FTTH 家庭,该公司表示,它现在可以为元界等未来应用准备好网络。

Telefónica Telefónica España 固定接入主管 Gonzalo Garzón 表示:“Telefonica 是西班牙第一家提供千兆连接的运营商,但我们不会止步于此。消费者的带宽需求永无止境,VR 游戏等令人兴奋的应用程序将始终不断发展,以充分利用可用带宽。新的 FTTH 技术为我们提供了比家庭连接更多的机会。随着他们容量的大幅增加,我们将能够在同一网络上提供新的业务服务。

诺基亚固定网络欧洲副总裁 Bjorn Capens 补充道:“得益于我们的 Quillion 芯片组,与 Telefonica 合作的 25G PON 概念验证表明,巨大的带宽容量可以很容易地添加到其现有网络中,与现有的 PON 技术共存。这意味着同一条光纤线路上的客户可以获得 GPON、XGS-PON 或 25G GPON 服务,从而更轻松地管理升级周期。

根据所选的光学器件,25G PON 支持对称比特率(下行 25Gb/s,上行 25G)和非对称比特率 (25/10)。虽然 Nokia 的高容量接入节点通常位于电信中心机房,但其部署用于大规模光纤部署。1 月初,诺基亚升级了 VodafoneZiggo 在荷兰的 IP 互连网络,将 7750 台服务路由器 (SR) 部署到 350 个站点。这意味着这个拥有 350 个位置的网络可以通过管道向 VodafoneZiggo 的消费者和企业客户提供数 TB 的通信和娱乐服务。

fttr就是起了个好听名字解决国内产能过剩的,实际有毛用

FTTR 实际上就是组网业务翻版,卖的是运营商维保服务。
