  • Introduction to the transmission distance of optical modules

    Introduction to the transmission distance of optical modules

    The transmission distance of an optical module is mainly limited by loss and dispersion. Loss occurs because the light energy dissipates due to medium absorption, scattering, and leakage during optical fiber transmission, dissipating energy at a certain rate as the transmission. Application Field: SR modules are the workhorses of data centers, facilitating high-speed connections for intra-data center communication. Among them, long-distance optical modules refer to optical modules with a transmission. After transmission through the optical fiber, the receiving interface converts the optical signals into electrical signals using a photodetector diode and outputs electrical signals of the corresponding bit rate after pre-amplification. ≥30km is long distance transmission.

  • What is the optical cable reel testing

    What is the optical cable reel testing

    Single reel inspection work includes: checking, counting, appearance inspection and measurement of the specifications and quantity of optical cables and connecting equipment transported to the site, and measuring the main optoelectronic characteristics. As we all know, in order to ensure the quality of optical cables and ensure that the optical cables can transmit communication models normally after installation, single reel inspection and reel matching must be carried out before the optical cables are laid, and strict inspections must be carried. Suppose you pull an optical-fiber or copper cable run, terminate it and test it. Finding the run faulty, you determine the problem is not with the terminations but with the cable, itself. Was the cable faulty to begin with--in which case you can invoke the cable manufacturer's guarantee--or was it. SmartReel™ revolutionizes the entire process by offering an efficient mean to assess the cable's status.
