> Are you saying we could use normal QSFP28 LR4 or ER4 modules with an amplifier in between? Yes, that is the idea from 30,000 ft. Fun fact, the ER4 optics you mention are amplified inside the pluggable in a very similar manner to how these EDFA systems work. Basically: QSFP28 100G ER <-> EDFA Amp

Re: 100GbE beyond 40km

My guess is that he was talking about the difference between a 100gbit/sec stream of ethernet frames with no error correction, and a 112gbit/sec (or so, depending on scheme) stream of transport with FEC (Forward Error Correction - which is essentially just cramming extra bits in there incase the

It seems that many of you are recommending the SolidOptics 1U appliances for this application. What do those cost? On Fri, Sep 24, 2021 at 6:01 PM Lady Benjamin Cannon of Glencoe, ASCE wrote: > > Above 40km I like coherent systems with FEC. You can feed the juniper into a > pair of SolidOptics 1

I just bite the bullet and use 3rd party optics. It’s easier and once you make the switch, lower cost. Ed Sent from my iPhone > On Sep 25, 2021, at 12:29 AM, Joe Freeman wrote: > >  > Open Line Systems can get you to 80K with a 100G DWDM Optic (PAM4) - > > I've used a lot of SmartOptics

Re: 100GbE beyond 40km

Open Line Systems can get you to 80K with a 100G DWDM Optic (PAM4) - I've used a lot of SmartOptics DCP-M40 shelves for this purpose. They also have transponders that allow you to go from a QSFP28 to CFP to do coherent 100G out to 120Km using the DCP-M40, without a need for regen or extra amps in

Re: 100GbE beyond 40km

Does this have to be Ethernet? You could look into line gear with coherent optics. IIRC, they have built-in chromatic dispersion compensation, and depending on the card, would include amplification. On Fri, Sep 24, 2021 at 1:40 PM Randy Carpenter wrote: > > How is everyone accomplishing 100GbE a

Re: 100GbE beyond 40km

Look into EDFA amplifier systems. They work over a range of bands and are pretty affordable. They can carry regular 1310nm as well as C-Band. Although if you are carrying C-band you may have to compensate for chromatic dispersion. Happy to help, I love this stuff! On Fri, Sep 24, 2021 at 4:39 PM
