D4 Fiber optic adapter is to achieve the same or different optical fiber connectors docking in optical links，make the light path connected under the small loss.It is to put the fiber of two surface precision docking, so that the optical output of light energy to the maximum coupling in the receiving optical fiber,and since it entered the optical link to minimize the effects on the system.Widely used in optical fiber
distribution frame (ODF), fiber optic communications equipment, instruments, etc., superior performance,stable and reliable.
Features:
Compliant with ANSI, Bellcore, TIA/EIA, and IEC standards Compact Design High Precision Alignment Low insertions loss and high return loss Excellent repeatability and changeability Simplex and duplex available With ceramic or metal ferrules Optical performance 100% factory tested
Application:
CATV Test Equipment Active Device/Transceiver Metro Networks Local Area Networks (LANS) Premise Installation Telecommunication Networks
