14 DBm Optical Transmitter, APC

When you see “14 dBm Optical Transmitter, APC,” it’s referring to specific characteristics of an optical transmitter used in fiber optic communication systems. Here’s a breakdown:

• Optical Transmitter:
  • This is a device that converts an electrical signal into an optical signal, which is then transmitted through an optical fiber.  
• 14 dBm:
  • This indicates the optical output power of the transmitter, measured in decibels relative to one milliwatt (dBm).  
  • 14 dBm signifies a specific level of optical power, which is important for determining the distance and signal strength of the transmission.
  • dBm is a logarithmic unit, so a higher dBm value means a significantly stronger optical signal.  
• APC (Angled Physical Contact):
  • This refers to the type of optical connector used.
  • APC connectors have an angled end face, which minimizes back reflections of light within the fiber.  
  • This is crucial in applications where back reflections can degrade signal quality, such as in high-bandwidth or analog optical systems.
  • APC connectors are generally used when very precise optical signals are required.  
• Applications:
  • These transmitters are commonly used in:
    • CATV (Cable Television) systems
    • FTTH (Fiber to the Home) networks
    • Telecommunications
    • Any application requiring long distance or high quality optical signal transmission.

In essence, a 14 dBm optical transmitter with APC connectors provides a relatively strong optical signal with reduced back reflections, making it suitable for demanding fiber optic application.
