Has any one use the (pump coupler counter-propagation) in optisystem

[adnan sabbar]

I installed a simple system consists of 10Gbps NRZ signal and cw pump laser mixed together across pump coupler co-propagating to a SMF. at the end of the fiber, the pump coupler counter-propagation connected. the Raman pump laser connected to this pump coupler counter-propagation. Raman pumping should enhance the conversion efficiency even with lower pump power.

but I didn’t see any effect of the Raman pump on the signal.

the wavelengths were, 1557, 1553, and 1455 nm for the signal, pump, and Raman pump respectively. I think the problem in the pump coupler counter-propagation,

 Please could any one can help me to solve this problem?

Hi Adnan,

I have been using the counter-propagating pump coupler since years, and never encountered this issue. Can you please share some more information regarding your design? Maybe you can post the .osd file too?

Best Regards,

Alessandro

I have same problem . Signal is not amplified when using coupler. Plz help me. I use Optisys v14. Thanks

I have uploaded my project simulating Raman Amplifier which compensating loss of 100km fiber, but it does not work. Plz help. Thanks

Hi Adnan,
I would suggest you to please visit following links:
As High-Power Counter-Propagating and Co‑Propagating Raman Amplifiers (Figure 1) operate in the C-band region of the optical spectrum to extend the reach and capacity of regional, long-haul, and ultra-long-haul optical networks beyond what is achievable through standard Raman amplifiers or Erbium Doped Fiber Amplifiers (EDFAs).
