据了解，25G DAC高速线缆由一根无源铜芯线缆与两个SFP28-SFP28接口的光纤收发模块组成，其收发模块形似光模块，但内部没有安装激光器。其实现短距离的数据传输有较强优势。

5G时代即将到来，随着5G网络的大规模建设，基站天线从2*2MIMO向4*4MIMO升级，推动了基站光模块从以6Gbps/10Gbps为主向以10Gbps/25Gbps/50Gbps为主升级，且25Gb/s速率光收发模块需求量快速上升。25G光模块产业链应用逐步替代10G光模块成为主流，数据中心、无线网、接入网、传输网对25G光收发模块形成了需求合力，5G时代25G光模块将是一个产业的爆发力。

江苏移动正积极布局5G网络，拓展5G应用。目前省内已建成208个5G基站，基础设施与技术能力强，在5G试点建设中是当之无愧的先行省份。

此前，江苏移动牵头成立了江苏省5G产业联盟。在江苏5G产业联盟的加持下，江苏移动的5G发展已步入快车道：携手爱立信和英特尔完成全球首例5G独立组网互通测试、南京首个5G基站“落户”青奥体育公园、建成全球首个5G无源波分复用基站等等一系列成绩表明江苏移动已全面开启5G建设。

此次25G无源光纤复用设备采购，是江苏移动为5G预商用进一步添砖加瓦。运营商积极扩大5G“朋友圈”，合力共建产业生态，这对通信制造企业也是极好的发展机遇，还需牢牢抓住！

C114 News April 8 (Jiaojiao) Recently, Jiangsu Mobile's public bidding for the 5G pre-commercial 25G passive optical multiplexing equipment project in 2019 will purchase 306 25G passive optical multiplexing equipment. The total purchasing scale is estimated to be 1989,000 yuan (including tax). The project is not divided into tenders, and the highest bidding price is 6500 yuan (including tax).

It is understood that the 25G DAC high-speed cable consists of a passive copper core cable and two optical transceiver modules with SFP28-SFP28 interface. The transceiver module is similar to the optical module, but no laser is installed inside. It has a strong advantage in short distance data transmission.

The 5G era is coming. With the large-scale construction of 5G network, the base station antenna is upgraded from 2*2MIMO to 4*4MIMO, which promotes the upgrade of base station optical module from 6Gbps/10Gbps to 10Gbps/25Gbps/50Gbps, and the demand of 25Gb/s optical transceiver module is increasing rapidly. The application of 25G optical module industry chain has gradually replaced 10G optical module as the mainstream. Data center, wireless network, access network and transmission network have formed a demand for 25G optical transceiver module. 25G optical module in 5G era will be the explosive force of an industry.

Jiangsu Mobile is positively laying out 5G network and expanding 5G application. At present, 208 5G base stations have been built in the province, with strong infrastructure and technological capabilities. They are well-deserved to be the leading provinces in the 5G pilot construction.

Before that, Jiangsu Mobile led the establishment of Jiangsu 5G Industry Alliance. With the support of Jiangsu 5G Industry Alliance, Jiangsu Mobile's 5G development has entered the fast lane: jointly Ericsson and Intel to complete the world's first 5G independent networking test, Nanjing's first 5G base station "settled" Youth Olympic Sports Park, the world's first 5G passive wavelength division multiplexing base station, and a series of achievements show that Jiangsu Mobile has fully opened the 5G construction.

The purchase of 25G passive optical fiber multiplexing equipment is a further step for Jiangsu Mobile's 5G pre-commercial use. Operators actively expand 5G "circle of friends" and work together to build industrial ecology, which is also an excellent development opportunity for telecommunications manufacturing enterprises, but also need to firmly seize!
