[c-nsp] No Link between SFP-10G-LRM and X2-10GB-LX4?

[quinn snyder]

are you sure that its supported?
lx4 == wwdm optic == 4x2.5gbps channels using wideband muxing.

additionally, when looking at datasheets for x2 and sfp+ modules, one
will see that lx4 optic mentions 4 lanes, launching in the 1300nm
space and a separate pluggable for x2-10gb-lrm.
sfp+ only mentions single lane in 1310nm space.

i dont believe the two are compatible. would suggest looking at
x2-10gb-lrm= for compatibility.

q.
