My company mainly produces fiber pigtail,Waterproof Fiber Pigtail,Bundle Fiber Pigtail,Ribbon Fiber Pigtail,attenuator,patch cord,Fiber Optical Pigtail,E2000 Fiber Optic Attenuator,MU Fiber Optic Attenuator,LC Fiber Optic Attenuator,FC Fiber Optic Attenuator,SC Fiber Optic attenuator,ST Fiber Optic Attenuator,Armored Optical Fiber Patch Cord,MPO Optical Fiber Patch Cord,E2000 Optical Fiber Patch Cord,MT-RJ Optical Fiber Patch Cord,MU Optical Fiber Patch Cord,LC Optical Fiber Patch Cord,FC Optical Fiber Patch Cord,SC Optical Fiber Patch Cord,ST Optical Fiber Patch Cord,Fiber Optic Splice Closure Box and other products. fiber pigtail connector with durable waterproof, easy installation, reliable,and can be connected to various types of connectors fiber pigtail of the product characteristics 1, the standard metal, zirconia ceramic ferrule 2, 8 bevel grinding 3, high return loss 4, the standard metal, zirconia ceramic ferrule Attenuator is a power loss of the RF / microwave components. Attenuator main purposes are: 1, adjust the size of the circuit in the signal measurement circuit 2 in the comparison, the network can be used to directly read the measured attenuation value of 3, to improve impedance matching, if some of the circuit requires a relatively stable when the load impedance , you can practice in this circuit and inserted between the load impedance attenuator, impedance change to the buffer 4, the control power level patch cord Product Description: patch cord is mounted on the motherboard, sound card, hard drive and other equipment on the small metal bar (jumper column), and set on a metal bar in the small clip (jumper clip). jumper is to adjust the different signals on the device on-off relationship, and this conditioned the work of the state, such as the motherboard voltage, the drive from the main relations. When the jumper put two folders at the same time when the jumpers column to indicate that these two jumpers column connected, if only put one or not put to that is broken. patch cord features: 1, the push-pull connection, fast and reliable 2, low insertion loss, high return loss 3, small size 4, high-precision mechanical dimensions 5, duplex connection
