With the feature of medium to low input power, medium output power, and medium gain, the pre-amplifier operates at the receiving end of an optical link to compensate for losses in a demultiplexer located near the optical receiver.
FS pre-amplifier is a low-noise, gain-flattened C-band optical erbium doped fiber amplifier (EDFA) designed to cost-effectively extend the optical link power budget for building long distance DWDM solutions.
* Note: Extended operation temperature (maximum temperature range of -40°C to +85°C) can also be provided, for more details, please contact at sales@fs.com for consulting.

13dBm Saturated Output Power for C-band Pre-Amplifier DWDM EDFA
Reducing the number of regenerators and sites along the fiber
Upgrading the optical link budget to support 10G services
Highly integrated with FMT management platform
Ideal Solution by Using DWDM EDFA
Optical EDFA Amplifier for Long-Haul Applications
Due to losses incurred in the light signal when passing through fiber patch panels, splices and the fiber itself, EDFA is needed to amplify the signal in long-haul transmission.
Single Fiber DWDM Solution with Pre-Amplifier
With PA used over a single fiber to realize bi-directional transmission, single fiber DWDM solution saves half of the fiber resources needed for transport.
Dual Fiber DWDM Solution with Pre-Amplifier
With PA used over dual fiber to realize bi-directional transmission, dual fiber DWDM solution enables better fiber utilization.

FS Powerful Network Management System
DWDM EDFA pluggable module is used with FMT chassis embedded with OSC for remote management and topology detection to be managed by our SNMPV1- based MonitorOnline. Our MonitorOnline provides complete performance monitoring and management, including laser shutdown status, input power, and output power etc. to centralize OTN network management.
No, it can't be adjusted via the Windows GUI. Taking the #72284 OPA13/G20 as an example, when the output power is lower than the saturated output 13dB, the gain is always 20dB; When it reaches 13dB, the gain will decrease as the input increases. If you want to purchase the EDFA with 20/26/28dB gain, it's recommended that you choose the 28dB unit, then you can use VOA(#65271) to artificially increase the precise attenuation to adjust the input/output power.

Sure, the operation Wavelength of the EDFA-PA is in the range of 1528nm~1564nm (C band), it can be amplified in this wavelength range. And the Pre-Amplifier only have one port, the input and output ports of DWDM EDFA-PA on our website are a simplex port. By FS on 10/29/2018
In order to avoid increasing the link loss, dispersion compensation is usually placed before the BA or after the PA, it should be noted the DCM that placed before the BA should not exceed 40km at most. By FS on 10/08/2018
No, the operating mode of DWDM EDFA is AGC by default, and does't support changes. And the APC operation mode DWDM EDFA is in development. By FS on 09/14/2018
I have shopped at FS for years. They made satisfactory customization and delivery every time. The Polarisation Maintaining EDFA I got this time worked as expected to boost 1 mW output of a c-band tunable laser to around 100mW, which we could monitor via the simple management tool. Had the module inserted in the 1U managed chassis sit on the rack. The modules themselves and the 1U chassis have proven to be of very good quality. Highly recommended!
We were interested in the EDFA but wondered whether the EDFA could work with our 200G DWDM module from another vendor, so we contacted the FS tech team for confirmation. They checked the datasheet of our module and assured us that the EDFA could work with the 200G module. Then they asked us about the optical loss of the whole link and recommended the 17dBm EDFA to ensure our power budget. The guys told us, we also needed an FMT chassis #39214 to install and manage the EDFA. At last, we bought two EDFAs and chassis. The chassis suit our 19-inch rack, and deployed EDFAs in our system, the 200G modules worked normally.
Looking for an EDFA to amplify 1531-1535nm wavelengths in our DWDM system. Asked the FS team whether #72284 supported. Their online support responded promptly. This product worked in the range from 1528nm to 1564nm, meeting our demand.
Great professionals; value, quality, price all excellent; personalized service
Always satisfied with the company over many years of purchasing. This time we needed a long-haul dual-fiber DWDM solution for 100G Ethernet transmission. I e-mailed my AM and told him the fiber type, site distance, and other details. He responded promptly and suggested a DWDM solution including products such as 100G DWDM CFP modules, 100G muxponder, 40CH Mux/Demux, EDFA, and so on. We further verified the solution and it was proved to be perfect for our case. Another good experience of receiving good and timely advice from FS, without any frustration or delay! Items arrived as scheduled and were exactly as described. And their tech support staff were very helpful when we had some problems in installing and setting up the system. Now the whole network and all the products do excellent jobs so far. Very responsive, great communication and customer service. Would definitely buy from them again in the future.
Good price and great detail about the product on the site
It is a great pre-amplifier for the price. I have used it in my fiber ring network for about 10 days, it performs very well and I have no complaints about the functionality.
I'm satisfied with the product and service of FS, all functional cards can be inserted into one managed chassis which saves a lot of space for other devices, and the management is also very convenient to configure all cards togather. When I had a qustion it was also responded to timel. Highly recommend this company for any other purchases.
Shipment arrived on-hand within 3 days, and the product is well-packaged. Adding it to the link and it works stably. Looking forward to future cooperation.
I had all the support I needed to select the solution and cleared all concerns, thanks for the engineer team that helped me a lot about my solution, they provided me a very clear diagram to understand. Shipping was also just as informed, it was all smooth, I recommend and bought myself from FS.
The pluggable card design EDFA is very easy to be intalled in the chasis without tools, and it also works well in the line. In the future I will add more and replace my old device.
