The high precision of the circuit board refers to the use of fine line width/spacing, micro holes, narrow ring width (or no ring width), and buried and blind holes to achieve high density. The high precision refers to the result of “thin, small, narrow, thin” will inevitably bring hi...

PON (Passive Optical Network) is a passive optical network, which means that the ODN (optical distribution network) between the OLT (optical line terminal) and the ONU (optical network unit) does not have any active equipment, and only uses optical fibers and passive components. PON mainly adopts...

Optical fiber transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. It is also called a fiber converter in many places. The product is generally used in the actual network environment where th...

Fiber optic transceivers are generally used in the actual network environment where Ethernet cables cannot cover and must use optical fibers to extend the transmission distance. They are usually located at the access layer of broadband metropolitan area networks, and are widely used in various mo...

An optical access network is an access network that uses light as a transmission medium, replacing copper wires, and is used to access each home. An optical access network generally consists of three parts: an optical line terminal OLT, an optical network unit ONU, and an optical distribution net...

In general, the luminous power of the optical fiber transceiver or optical module is as follows: multimode is between 10db and -18db; single mode is 20km between -8db and -15db; and single mode is 60km is between -5db and -12db between. But if the luminous power of the fiber optic transceiver app...
