Although there are blackhat approaches which can get backlinks indexed slightly faster, I wouldn't recommend. Reason being, Google will find your backlinks naturally - and usually very quickly. If Google values the website which is linking to your website, it should take no time at all for them to crawl it and find the backlink(s).
As for the blackhat approach, to me it's pointless, but there are services like onehourindexing.co, although I highly recommend letting Google naturally crawl. I literally see no benefit of trying to rush the process, while dipping your feet into blackhat SEO unnecessarily.
