product description
The GK-PMTC series coupler is designed to meet the demanding requirements of optical communication systems. It operates effectively in a wide wavelength range of 1310 nm and 1550 nm, with a center wavelength tolerance of ± 40 nm. The features of this coupler include:
Low insertion loss: ensures minimal attenuation of the signal when passing through the coupler, thereby improving the overall efficiency of the system.
High isolation: Provides excellent back reflection isolation, reduces signal reflection, and enhances system stability and performance.
High power processing capability: capable of withstanding up to 300 mW of continuous optical power, making it suitable for high-power fiber laser and instrument applications.
Wide temperature range operating capability: It can operate within a temperature range of -5 ° C to+70 ° C and withstand storage temperatures of -40 ° C to+85 ° C, ensuring stable performance under different environmental conditions.
High quality fiber optic: SMF-28 or Panda fiber optic is used as the tap port, with Panda fiber optic as the input and output ports, ensuring reliable performance and durability.
Durable design: including a maximum tensile load capacity of 5 N, making it suitable for various installation environments and ensuring mechanical stability under different conditions.
These characteristics make the GK-PMTC series couplers an ideal choice for applications such as fiber lasers, fiber sensors, and high-performance networks. They can maintain performance under harsh conditions, provide precise power allocation and monitoring functions, thereby meeting the requirements of high-speed communication systems for signal integrity and high fidelity.
