Optical modules are essential components in enterprise networking. According to different rates, encapsulation types and interface types, optical modules can be divided into different categories, one of which is the electrical port module. In the daily enterprise networking, compared with the widespread use of optical modules, electrical modules are not common, is it that the optical module is hig

For normal fiber broadband, the ideal range of light attenuation is -20dBm to -25dBm. For speeds up to 200M, the light attenuation must be less than -25dBm. With light attenuation at -27dBm, speeds are limited to a maximum of 100M, and with light attenuation at -28dBm, speeds are limited to a maximum of 50M.What is light attenuation?Light attenuation generally refers to its luminous flux, when cha

There is a range limit for the light harvesting power of the optical module of the network equipment, when the light power is lower than the allowable range, the phenomenon of network packet loss will occur, affecting the quality of network communication; when the light power is higher than the allowable range, it will shorten the life of the optical module, or even damage the optical module. Ther

Below 180mA, according to the working principle of optical module, normal 1.25G optical module working current is below 180mA to work normally, so the working current of optical module is below 180mA. However, with the increasing use of time limit, many of the old module operating current will be more than 220mA, so this module will be very hot in the working state, when the ambient temperature be

Currently, under the call for 100G, 200G, and 400G high-speed optical modules, 40G QSFP+ optical modules have been widely used in access links. 40G/100G Ethernet is an Ethernet standard developed by the IEEE 802.3ba Group, supporting the transmission of 40/100Gb Ethernet frames per second, and establishing physical layer specifications for communication through backbone networks, copper cabling, m
