  • Function analysis of amplifier in medium and long distance optical module
    Function analysis of amplifier in medium and long distance optical module
    • January 19. 2022

    In optical fiber communication, when optical fiber transmits optical signal, the optical signal will attenuate along the optical fiber transmission path, and the transmission distance is limited by optical fiber attenuation. In order to transmit the signal further, we need to enhance the optical signal. The traditional method of enhancing the optical signal is to use the regenerator, but it has ma...

  • What are 10G SFP+ CPRI optical modules?
    What are 10G SFP+ CPRI optical modules?
    • January 14. 2022

    CPRI is the abbreviation of common public radio interface. CPRI plays the role of transmitting baseband I / Q signals to radio units in traditional BS (base station). CPRI has efficient and flexible I / Q data interfaces for various standards, such as GSM, WCDMA, LTE, etc. Unlike the data center, the CPRI optical module used in the base station has a constant temperature environment, and its worki...

  • What are the 10 GBIT/s SFP+ Optical Modules with a Transmission Distance of 40KM?
    What are the 10 GBIT/s SFP+ Optical Modules with a Transmission Distance of 40KM?
    • January 13. 2022

    Although 40 GBIT/s and 100 GBIT/s data centers are developing rapidly, 10 GBIT/s optical modules are in high demand in most application scenarios. For example, the computer rooms of many schools, organizations, and companies are still based on 10 GBIT/s Ethernet. Among them, 10 GBIT/s SFP+ optical modules occupy the largest market share. This article is easy to day light communication (ETU-li...
