Outdoor Fiber Optic Cables

SDGI is one of the earliest high-tech enterprises in China to develop and focus on optical fiber and cable, roviding various types of outdoor optical cables such as duct, aerial, direct buried, underwater, and other types.
Detail

Indoor Fiber Optic Cables

Indoor optical cables are mainly used for optical network wiring in buildings, optical fiber access networks, and data rooms, etc. Indoor optical fiber cable to provide optical network connections for communication equipment, computers, switches, and end-user equipment.
Detail

Power System Fiber Optic Cables

Power system optical cables mainly provide professional power communication for the power grid. It has good matching with the conductor and earth Wire, almost the same mechanical and electrical performance, and strong environmental adaptability. The composite fiber optic cable is suitable for all kinds of power lines, mainly high-voltage lines of 35kV and above. At present, the highest has been put into operation in ±800kV DC and 1000kV AC lines.

Single mode fiber

SDGI’s SMF single mode fiber can ensure the best performance in the 1310nm and 1550nm windows (including the L-band of 1565-1625nm), and minimize the dispersion in the 1310nm working window. SDGI single mode fiber is suitable for optical cable products of all structures, such as loose tube type, tight sleeve type, ribbon, and central tube type. And in use, it is compatible with optical fibers produced by other processes. SDGI single-mode fiber can be widely used in high-speed, long-distance transmission, such as long-distance communications, trunk lines, cable television, and loop feeder networks. All of SDGI’s optical fiber products use a unique double-layer UV-curing acrylate coating process, which will ensure the reliability and durability of the optical fiber and provide the best performance even in the harshest environment. The performance of SDGI single-mode fiber meets and is better than ITU-TG 652B, IEC60793-2-50B.1.1, and other optical fiber technical specifications. In order to make it more convenient for customers, stricter standards have been formulated for various indicators of optical fiber products. If you want to know the discount price of single mode fiber, please contact us.
