Fiber Raman Amplifier 1425- 1565nm | SIMTRUM Photonics Store

1^st Order Distributed Fiber Raman Amplifier 1528-1565nm

SIMTRUM’s Fiber Raman Amplifier utilizes the Raman scattering effect in quartz fiber to provide signal gain, offering flat gain spectrum and wide bandwidth. The first-order Raman amplifier uses 14xxnm laser as the Raman pump to amplify C-band signals, effectively compensating for signal attenuation in long-distance fiber transmission. Ideal for long-haul optical transmission systems and distributed fiber sensing systems. ^{*Note 1}

Features

• Wide wavelength range
• High gain factor
• Low noise figure

Applications

• Long-distance fiber-optic communication
• Fiber-optic distributed sensing
• Fiber laser

*Note 1: This amplifier serves as a Raman pump and requires the user’s system fiber to generate Raman gain. It is not a discrete Raman amplifier; for transmission systems over 50km, a distributed Raman amplifier is recommended.

*Note 2: The gain of a distributed Raman amplifier refers to the signal power comparison at the system receiver with the Raman pump on and off (On-Off Gain), which differs from traditional amplifier gain. The actual effect depends on factors like fiber type, length, signal wavelength, and power. Typical values are for reference.

2^nd Order Distributed Fiber Raman Amplifier 1425-1465nm

SIMTRUM’s Second-Order Fiber Raman Amplifier builds on the first-order amplifier by adding pump lasers in the 1340~1360nm range to provide Raman gain for the 14xx nm first-order Raman laser. This effectively reduces system noise and is suitable for amplifying optical signals in longer distance relay-free transmission systems. The second-order amplifier must be used in conjunction with the first-order Raman amplifier for optimal performance. 

Features

• Wide wavelength range
• High gain factor
• Low noise figure

Applications

• Long-distance fiber-optic communication
• Fiber-optic distributed sensing
• Fiber laser

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.
