Fiber Optic Receiver With AGC and Wdm

Our Passive FTTH fiber optic receiver is an essential component for bringing fiber access to households.

It is designed for use in FTTH (fiber-to-the-home) networks, enabling analog or digital signal access to homes.

—High-quality plastic shell
—Input power range +2~-10dBm.
—No power supply, no power consumption
—Output level≥65dBuv(PIN=+0dBm)


The optic receiver is a home-use optical receiver for FTTH (Fiber to the Home) network optical fiber access terminals to enable analog or digital signals to enter the home.
The machine uses low-power photodetectors GaAs and optical AGC technology to meet the fiber-to-the-home CATV reception needs. Many functional products are slightly different in application.

Product Details

1. Fiber Optic Receiver types

Fiber optic receivers are categorized into two types: digital and analog.

Digital receivers detect incoming optical signals from optical fibers, amplify digital photo current, and reshape the signal to create an accurate electrical signal. They are commonly used in a wide range of digital transmission applications.

Analog receivers pick up incoming optical signals and amplify the resulting photo current.

The architecture of digital fiber optic receivers is similar across a range of low-data-rate applications, typically utilizing PIN diodes and high-impedance amplifiers.

2. Optical Receiver Design

Fiber Optic Receiver Manufacturer

Optical receivers typically consist of four main components: the front end, linear channeldecision circuit and clock-recovery circuit. Here’s a brief overview of each component:

  1. FRONT END: The front end of an optical receiver consists of a photodiode followed by a preamplifier. The photodiode converts the optical signal into a time-varying electrical signal. The preamplifier amplifies this signal for further processing.
  2. LINEAR CHANNEL: The linear channel of an optical receiver includes a high-gain amplifier (the primary amplifier) and a low-pass filter. An equalizer is often used before the amplifier to compensate for limited front-end bandwidth. The amplifier gain is automatically adjusted to maintain a constant output voltage regardless of the incoming optical power. The low-pass filter shapes the voltage pulse.
  3. DECISION CIRCUIT: The data-recovery portion of an optical receiver comprises a decision circuit and a clock-recovery circuit.
  4. INTEGRATED RECEIVERS: All receiver components, except for the photodiode, can be integrated on the same chip using microelectronic device technology. Integration is particularly important for high-speed receivers.

3.  How to Choose Fiber Optic Receiver

1. Does fiber optic receiver support full-duplex and half-duplex?

Some chips on the market can only be used in full duplex environment and cannot support half duplex. If it is connected to another brand of switch (SWITCH) or hub (HUB), and it uses half duplex mode, it will definitely cause serious conflicts and packet loss.

2. Have you tested the connection with other fibre optic receiver?

There are more and more fiber optic transceivers on the market nowadays. If the compatibility between different brands of transceivers is not tested beforehand, packet loss, long transmission time, fast and slow transmission will also occur.

3.Is there a security device to prevent packet loss?

Some manufacturers in the manufacture of fiber optic transceiver transceiver, in order to reduce costs, to the outside of the register (Register) data transmission mode, the biggest drawback of this way is that the transmission is unstable, packet loss, and the best is to use buffer line design, can safely avoid data packet loss.

4.Temperature adaptability?

The fibre optic transceiver itself generates high heat when used, when the temperature is too high (not more than 85°C), does the fibre optic transceiver work properly? It is a very worthy factor for customers to consider!

5.Does it comply with IEEE802.3u standard?

Fiber optic transceivers are compliant with the IEEE802.3 standard, i.e. the delay time is controlled at 46 bits, if it exceeds 46 bits, the distance transmitted by the fiber optic receiver will be shortened!
