booster to gain distance above 60km
Hi folks we have a point and have a 63km between point A to point B. We have a sigle fiber ( only one fiber) and use a fiberstore sfp+ 10GB dibi 1270/1330 module to connect these sites. All attenuation are okI don¹t have any trouble on fiber . I have received this signal on my sfp+: Receiver signal average optical power : 0.0026 mW / -25.85 dBm Does anyone know if have some possible to amplifier this scenario to get more 7db ? Is it possible to put any booster or any way to solve this? I think to use a optical PreAmlifierbut I don¹t know if is possible because my scenario have just one fiberor, use a ROPA- remote optical pumping amplifier) because I have 63km Does anyone have some idea?

Hi The easy way to get 63 km is to use a SFP+ module that is rated for 63 km. Fiberstore has 60 km BIDI SFP+ for USD 325 and 80 km BIDI for USD 425. If you want to use a booster you would need DWDM modules instead. And you have to add in the DWDM splitter and two boosters. For each end of the link it would be USD 435 for the SFP+ module, USD 174 for the BIDI DWDM splitter in a rack chassis and USD 1300 for a 13 dBm output booster. So - forget about the booster and just get the 80 km BIDI modules. Regards, Baldur On 26 March 2015 at 13:07, Rodrigo Augusto <rodrigo@1telecom.com.br> wrote:

I needed them for an application a few months ago and had to take a new approach when I only could find 60 km ones.

Already use this bidi sfp+ to 80km from fiberstore... But i can't link two sides... Have -24dbi... Everything alright with fiber... If i using this circuit with this signal i will have many trouble... I wiil buy a dwdm simplex solution from fiberstore again to use on this curcuit... What booster and preamplifier i have to use on it?! I will buy a 8channel simplex ... C21/c51, c22/c52 etc.... Do you know what a booster and an amplifier i have to buy?

In my experience I would say you probably have dirty connectors, and all you need to do is to clean all connections along the fiber or possibly straighten out any too tight bends you might have. You only gave us the output at the far end. We also need the output directly from the module to calculate the optical power budget. Note that the fiber attenuation is higher at 1310 nm than 1550 nm. So you will gain extra power just by switching to 1550 nm modules. Amplifiers only work at 1550 nm. Typical loss is 0.4 dB/km at 1310 and 0.3 dB/km at 1550. With new fiber it can be as low as 0.22 dB/km at 1550. With a power budget of 23 dB that is more than 100 km. You will however lose a little to insertion loss in the WDM. To work with 1550 nm you would buy two 1550 nm DWDM modules. Remember to use different channels on each module: http://www.fiberstore.com/10gbase-100ghz-dwdm-sfp-80km-single-mode-optical-t... You will need a DWDM Mux type A in one end of the link and type B in the other end: Type A: http://www.fiberstore.com/2-channels-type-a-1ru-rack-mount-simplex-bidi-dwdm... Type B: http://www.fiberstore.com/2-channels-type-b-1ru-rack-mount-simplex-bidi-dwdm... You will actually only need one channel, but they do not appear to have that. So you get another channel, which you could use to make a dual 10 Gbps link. This should work without amplifiers for the given distance. If you do want to add amplification, you could either amplify the output of the module with a booster or you could amplify the input to the module with a preamp. I have no experience in doing that, so I can not tell which option is better. The booster is slightly cheaper.

Sorry I forgot to read you message properly. You are saying you want 8 channels - note this will give you twice as much insertion loss compared to two channels and might tip the balance towards requiring amplification. You should also ask Fiberstore for advice for which channels you choose, as there might be a huge difference in loss. You can not amplify the single fiber. The amplifier will not tolerate a BIDI signal. You will therefore need to amplify each channel in separate amplifiers and that becomes very expensive. In theory the signal could be split using an optical circulator: http://www.fiberstore.com/c/optical-circulator_1311 and then you could amplify either RX or TX - probably you would want to amplify RX to sidestep issues with feedback and reflections disturbing the amplifier. I never tried this but I am very curious if it actually works... Regards, Baldur On 28 March 2015 at 20:14, Rodrigo 1telecom <rodrigo@1telecom.com.br> wrote:
