”Splice loss is a function of core alignment and the quality of the fusion splicer. Basically a fusion splice that’s not terrible as in generally .1-.3 dB”

So is there really as much of a bad splice problem out there as someone wrote earlier in this thread?

If so, you’d think they’d have fixed them as soon as they were made.

Well I see one post on here probably from an actual transport engineer because that person was not trying to impress anyone with none sense. There are many 100 G waves turned up all over the place on 40 channel Cisco 15454 most of them done during the CAF 2 projects and all of them working just fine. Splice loss is a function of core alignment and the quality of the fusion splicer. Basically a fusion splice that’s not terrible as in generally .1-.3 dB , a span loss that’s within budget and CD and PMD reading that are not crazy are all you need. CD and PMD can be compensated for to some extent using a DCM. Not usually needed. Unless the fiber is from the 80s and won’t pass anything in the 1500 nM range it will work on a DWDM system.

I had to escort a vendor for a few new legs of winterstate turnups so he could do fiber characterization testing.....win wouldnt buy us the test sets. Every single leg failed, but our engineer said “its close enough”. No repairs were made and we went live. And example of why there are so many repair issues.

A 40 channel DWDM is not specific enough. How many 100Gs per channel using what modulation for what distance? Better go back to your friend for answers

what's with all the splice losses?

Well take it from an old engineer who turned up a boat load of Cisco 15454 all over the place at WS. Most of the fiber will run a 40
Channel DWDM system just fine. All you fiber tranport experts need to chill.

The ILEC portion is tied at the hip to the the CKEC side for long and metro hauls. All ILECs eventually need connectivity to long haul. The argument that one side is not connected to the other is false.

all that old stuff buried, aerial or in conduit? If it's buried, good luck replacing.

@11ZObSpf-1jhf:
"Yep DSF...not good for high capacity DWDM."

You mean the old dispersion-shifted fiber from the 80s and 90s that was optimized for single wavelength operation at 1550 nm for long spans?

I'm guessing this is on the CLEC side - it's hard to see the ILEC side needing long span

The high splice losses - are they getting worse or have they always been bad?

I'm assuming the cable is still holding up, physically?

Sounds like you've got your hands full.

Yep DSF...not good for high capacity DWDM. The large splice loss points that take mountain moving efforts to access and repair. In other words, high loss points don't get fixed. Many fiber cables are shared....and also do not fixed
Again why is the SEC so absent is the big qestion... does anyone really the the are being honest and truthful. Do you think the gbots even know what GAAP means

"the fiber is old, wrong type for high capacity transport"

I'm curious – how is the fiber a problem?

What kind of fiber is it (standard singlemode? NZDF?)

Thanks

Nobody wants the assets tied to the MLA......Including windstream. Copper is worthless long term and the fiber is old, wrong type for high capacity transport systems. I know. I deal with it daily. Why the SEC has not stepped in to stop these Gunderman pukes and TT is the pertinent question
