‘Ghost’ events in Optical Time Domain Reflectometer (OTDR)
Optical Time Domain Reflectometer (OTDR) is a widely used instrument in fiber optic testing. The purpose of OTDR is to detect, locate, and measure optical events at any position in the fiber optic link. The optical events include splice loss, connector loss, fiber attenuation, and faults. The single-ended nature of OTD...Read more -
Optical Fiber Access Technology: EPON, GPON, 10G EPON and 10G GPON
EPON and GPON are two common optical fiber access technologies. They use optical fiber to transmit data and provide users with high-speed, large-bandwidth Internet access services. EPON is based on Ethernet technology, while GPON adopts the ITU-T G.984 standard. The two have some significant differences in architecture...Read more -
How Does a Fiber Identifier Work?
Optical fiber identifiers are designed to non-invasively identify continuous-wave signals in fiber optic cables. They are low cost, hand-held tools that identify signals in single-mode fiber without interrupting service or damaging the fiber. Optical fiber identifiers eliminate the need to open the fiber at the splice ...Read more -
14 Common Problems and Solutions When Using Fiber Fusion Splicers
1. Welding loss is too large The cause of this failure can be analyzed from the following points: (1) The end face of the fiber is not clean and dusty, or there is debris on the V-shaped groove, or there is debris on the fiber holder. (2) The Angle difference of cutting end face of fiber is too big. (3) Problems with t...Read more
