Good news about almost all optics, their Rx window is pretty wide. Meaning a
1550nm optic will activate the receiver on a 1560nm optic just fine (and
probably anything in the 1500nm band). Careful use of specialized single
strand DWDM muxes (FS.com) can yield great bidi-like results with
Something that is broadly the same as a coherent 100G QPSK single
wavelength optical module, but in two different frequencies, and a passive
CWDM mux/demux prism at each end might work. The limitation would be
availability of optics for a modern 100G MSA that are both coherent and
Tx/Rx at two
Anyone from DAZN here, or anyone know what CDN is used for their content? I'm
specifically curious about NFL Sunday Ticket content in case it makes a
difference.

Non-coherent receivers usually seem to even when paired with DWDM grid
transceivers. You're paying for the tightly controlled laser on those,
not so

If we were talking 10G, adjacent channels, add a TFFL filter it *Should* work.
100G isn’t just on-off at a high clock rate, it’s also modulated around the
center frequency, I don’t think it’d work even with a wideband receiver.

For 1 and 10Gbps OOK modulation yes, but not for something like a ITU DWDM
grid channelized or tunable coherent optic. In which the (QPSK, 8PSK,
16QAM) signal has a specific THz width and frequency not unlike a radio
operating in a very, very narrow waveguide.

You would still need to frequency shift TX and RX. They are travelling
opposite directions on the same piece of glass; as the traffic rate increases
the likelihood of collisions increases and you’ll start to get errors. The
collision would either cancel the ‘bit’ or act like OBI and get

Thanks again. This is at least the third time someone has pointed this
