You are 1 split (3.5db) too deep for my liking. But like others said, if it aint broke...
If you were able to reconfig a splitter so that you can drop a 3.5 you would be golden.
3way (3.5db / 7db / 7db)
If you could get the leg of the outlet with the modem onto a 3.5 instead of a 7, you would end up with ~ -2 on the downstream and 48.5 on the upstream.
S/N is already at almost 38 on all downstreams and is more than perfect.
But thats just me. If speeds are fine, all of this is unnecessary.
I second that, if he's not already on the -3.5 leg of a 3-way splitter.
Other than that, the signal strength is 100% within spec: there is no "better" and no reward for being anywhere on its scale, except for the very edge.
As the OOL FAQ was mentioned in this thread - I took a look, and didn't like what I saw there, and left the following feedback, summarizing what I've posted here on more than one occasion before:
The OOL plant build standard (enforced on the techs with an in-home test) is Receive Power from -10dBmB to +10dBmV, while transmit is up to +54dBmV (DOCSIS2 US limit for CV's 64QAM US channels) - there's no low Tx Power limit, but you're unlikely to ever encounter values lower than +30dBmV.
The FAQ statement of "closer to the center = better" is blatantly and 100% wrong : the only way to accomplish that for everybody is to move every house on that node segment into the exact same location (
The correct statement is, and MUST be: DOCSIS will operate correctly and with acceptable error rates (BER/MER) and with no significant frame (and packet) loss anywhere in this range.
Marginal values near the very edge of the spec could become problematic at times, as signal levels vary by outdoor temperature. A +54dBmV transmit power is like a problem, as modems cap their Tx power per the spec - while the headend may receive less signal than spec'd (below 0 dBmV), but this cannot be seen from the modem side. The only way to ensure that the headend is not "under water" is when the Tx Power is = +53dBmV - that 1dB of margin is easily consumed by changing environmental conditions.
