10 +10DBM Transmitter With Optical And RFIN

When you encounter a description like “10 +10DBM Transmitter With Optical And RFIN,” it refers to a specific type of optical transmitter commonly used in CATV (Cable Television) and fiber optic distribution networks. Here’s a breakdown:   

• Optical Transmitter:
  • This device converts RF (Radio Frequency) signals into optical signals (light) for transmission over fiber optic cables.
• 10 +10 dBm:
  • This indicates the optical output power of the transmitter. “dBm” is a unit of power expressed in decibels relative to one milliwatt.   
  • In this case, “10 +10 dBm” often signifies that the device has multiple optical outputs, and each output provides approximately 10 dBm of optical power. So in some cases it can also be interpreted as a total output of 20dbm.
  • This is a measurement of the strength of the optical signal that the device is capable of transmitting.
• Optical And RFIN:
  • This means the transmitter has both:
    • Optical Input: It may be able to receive an optical signal, allowing it to be used in certain network configurations.
    • RFIN (RF Input): It accepts traditional radio frequency signals from sources like cable television headends.
  • This dual capability gives the device flexibility in how it’s integrated into a network.

In essence:

This type of transmitter is designed to take RF signals, convert them to optical signals with a specified power level, and then send those signals through fiber optic cables. This is crucial for distributing television and data signals over long distances with minimal signal loss.

Key applications:

• CATV networks
• FTTH (Fiber to the Home) networks
• Optical signal distribution

When looking at these devices it is very important to pay close attention to the wave length that the device is transmitting at.

1310nm and 1550nm are very common wave lengths.
