Filling Gel for Optical Fiber Loose Tube
XF-400 filling gel for optical fiber loose tube is specifically designed for optical fiber loose tube at high line speeds. Its best working temperature is room temperature, with the temperature rises, its viscosity will gradually decrease.
XF-400 filling gel for optical fiber loose tube is thixotropic,suitable for cold filling. It can inhibit the growth of mold, has excellent oxidation resistance and long-term stability .

Nokia and SFR Complete First 3.5GHz 5G NR Call Test in France
Nokia recently announced that it has cooperated with SFR and successfully completed the 5G call test in the 3.5GHz band through the 5G new air interface (NR) system that conforms to the 3GPP standard. On May 3, 2018, the two parties completed the test at the Nokia 5G Test Network and Competence Center at the Sacred Innovation Base in Paris, France.
The 5G call test adopts Nokia 5G NR technology, which integrates the Nokia 5G-ready AirScale wireless platform and Cloud RAN technology, as well as end-user test equipment conforming to the 3GPP standard. In order to support the Cloud RAN, Nokia has also built a cloud infrastructure through the Nokia AirFrame data center solution.
In December 2017, 3GPP announced the completion of the 5G new air interface (NR) standard, which supports multiple 5G applications and enhanced mobile broadband (eMBB) services. The Nokia 5G NR system utilizes smart antennas to deliver multi-gigabit throughput and millisecond-level low latency. This will enable operators such as SFRs to increase network capacity in frequency bands below 6 GHz, thereby achieving broader coverage.
Nokia is the main supplier of SFRs, especially in the wireless access network solutions section. SFR is committed to standing at the forefront of innovation and continuously satisfying customer needs. The milestones achieved by both parties in this test are fully consistent with this goal.
Fraros Vincent, head of the SFR mobile network, said: "The SFR is developing a network evolution plan to fully reflect the various benefits of deployment of 5G and consider the complexity of the implementation process. This joint project and testing will enable us to The most effective way to meet future data needs while exploring new ways to deliver media content that enhances the user experience.”
Marc Rouanne, president of Nokia Mobile Network, said: "Nokia is very excited to help SFR accelerate the implementation of 5G deployment and develop new business models to enrich the user experience. Through 5G technology testing, we can enable SFR to continue to meet the massive data needs of customers while Help operators launch next-generation services."
