1st Order Fiber Raman Amplifier 1528-1565nm

 

Fiber Raman Amplifier uses the Raman Scattering effect in quartz fiber to provide gain for optical signal. 14xxnm laser is used as Raman pump to provide gain for signal light in C or L band, which can effectively compensate the attenuation of optical signal in long-distance  optical fiber transmission. It is suitable for long-distance optical transmission system and  distributed optical fiber sensing system.

*Note 4 - The amplifier is only a Raman amplifier pump, which needs to cooperate with the long-distance quartz fiber in the user system to produce sufficient signal gain.

 


2nd Order Fiber Raman Amplifier  1425-1465nm

 

Based on the 1st-order Fiber Raman Amplifier, the 2nd-order Fiber Raman Amplifier adds a 13xxnm pump laser to provide Raman gain for the 14xxnm laser of the 1-order Raman, which can effectively reduce the system noise and is suitable for optical signal amplification in longer-distance repeater free optical transmission systems. The 2nd-order fiber Raman amplifier needs to be used together with the 1st-order fiber Raman amplifier.

What is a Raman amplifier? How to use it?


Please refer to the SIMTRUM website for the Fiber Raman Amplifier. The fiber Raman amplifier uses the Raman effect in the silica fiber to provide gain to the optical signal and realizes high gain and low noise amplification for the optical signal in the C or L band, which can effectively compensate for The attenuation of optical signals in long-distance optical fiber transmission is usually used in long-distance optical transmission communication systems, distributed optical fiber sensing, and dense wavelength division multiplexing optical transmission systems. For the C-band signal with a wavelength around 1550nm, a Raman pump laser with a wavelength of 1420~1465nm is generally used. The signal light and the Raman pump light simultaneously enter the long-distance transmission fiber through WDM, which constitutes a distributed fiber Raman Amplifier; for signals of multiple wavelengths distributed in the CL band, the Raman pump also needs to select multi-wavelength pumps from 1420 to 1500 nm to achieve flat gain, as shown in the figure below (multi-wavelength signals in the C-band, transmission length of 20km, ordinary single-mode Fiber, Raman pump wavelength 1425-1465nm, power 1 watt). The Raman amplifiers we provide are mainly Raman pumped lasers, wavelength division devices, and gain fibers that can be provided by users, and we can also provide them. It should be noted that the gain of the Raman amplifier refers to the comparison of the signal power at the receiving end of the system when the Raman amplifier pump is turned on and off, also known as the switching gain, such as the one-way communication system in the figure below, signal light and pump light. In the same direction transmission, the signal optical power is detected at the far end.



One-way fiber optic communication


The Raman gain given in the product information is for a test system we built, using a 20km single-mode fiber, which is equivalent to an example demonstration. It does not mean that customers can use this pump to produce exactly the same gain in their own system. It may be larger than that in our data, or it may be smaller than ours. We do not have the final gain effect of the Raman amplification system built by customers. Guarantee (the gain depends on many factors in the system), customers choose different Raman pump power according to their own situation when placing an order; we only guarantee that the wavelength and power of the Raman pump conform to the contract or product data nominal parameter.


A Raman amplifier has been added to our user's case of distributed fiber optic vibration sensing system (schematic)
