Troubleshooting/solution

What should I do if the temperature of the optical module is too high? How to solve?

The optical module is a relatively sensitive optical device. When the operating temperature of the optical module is too high, it will cause problems such as excessive transmit optical power, received signal error, packet loss, etc., and even burn the optical module directly in severe cases. If t... Read More

Several lights of the Optical fiber modem are normal and the status of the Optical fiber modem light signal is normal and the failure analysis

There are many signal lights on the fiber optic modem, and we can judge whether the equipment and the network are faulty through the indicator light. Here are some common optical modem indicators and their meanings, please see the detailed introduction below. 1. In order to facilitate the locatio... Read More

What are active (AON) and passive (PON) optical networks?

What is AON? AON is an active optical network, mainly adopts a point-to-point (PTP) network architecture, and each user can have a dedicated optical fiber line. Active optical network refers to the deployment of routers, switching aggregators, active optical equipment and other switching equipmen... Read More

How to achieve high precision PCB?How to achieve high precision PCB?

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... Read More

Ten common faults and solutions of optical fiber transceivers

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... Read More

How to judge whether there is a problem with the fiber optic transceiver?

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... Read More
