The RG11L-A110 is an active electronic device used for polarization and linearization of signals in optical networks. It is an important component in optical systems, and its main function is to improve the signal-to-noise ratio, reduce the channel distortion, and improve the overall transmission quality of the optical network.

Applcation Field

The RG11L-A110 is widely used in the optical communication systems. It can be used in all kinds of optical networks, including Ethernet, fiber optics, CATV, cellular, enterprise and other networks. In addition, the RG11L-A110 can also be used in the transmission systems of the military. RG11L-A110 can also be applied to the passive optical network (PON) and fiber to the home (FTTH). In addition, it can be used in cable TV (CATV), base station optical amplifier and optical line terminal amplifier, point-to-point optical communication, wireless optical broadband, optical fiber access, relay optical fiber access and related systems.

Working Principle

The working principle of RG11L-A110 is based on the principle of light coupling. It is mainly composed of three large components: the optical transmitter (OT), the optical receiver (OR) and the optical cavity (OC). The OT generates the polarization controlled light and creates polarization diversity, while the OR receives and processes the received light. The OC is the part that couples the optical signals between the OT and OR. It includes the polarization beam splitter, that can divide the single polarization light into two horizontal polarization light beams, and the directional coupler which can combine the two optical signals into one output.

The OT and OR can work in different modes, such as linear, circular, wideband, narrowband, polarization and polarization diversity. The OT and OR can also work in the same mode. The linear mode produces the best signal characteristics, and the circular mode is suitable for applications requiring a wide range of polarization. The wideband mode is suitable for applications requiring high polarization power, while the narrowband mode is suitable for applications requiring low polarization power.

In addition, the RG11L-A110 also includes several modules, such as a signal polarization controller (SPC) and a band-pass filter (BPF), for further processing of the optical signal. The SPC can provide adjustable device parameters, such as polarization angle, optical power and gain, to adjust the bias current of the OT. The BPF can eliminate parasitic signals and strengthen the OT signal at the same time.

The RG11L-A110 has two operation modes, namely, continuous wave (CW) mode and non-continuous wave (NCW) mode. In the CW mode, the device operates continuously and can provide a better linearity and signal transmission. In the NCW mode, the device operates intermittently and is suitable for application in places with higher optical power requirements.

The RG11L-A110 is an important component in optical systems, and its main functions are to improve the signal-to-noise ratio, reduce the channel distortion, and improve the overall transmission quality of the optical networks.
