10GBASE-SR is a port type for MMF (multimode fiber) and uses 850 nm lasers. For longer reach,another standard defined in IEEE 802.3ae is 10GBASE-LR.10GBASE-LR is a port type for SMF (single mode fiber) and uses 1310 nm lasers. Traditionally SMF 10GBASE-LR SFP+ modules are way more expensive than MMF 10GBASE-LR SFP+ modules. MMF and SMF historical short range / long range paradigm may change in short term:since 2014,for new installations,especially indoor,SMF wiring is about half of MMF wiring. As a consequence,lots of new buildings and datacenters now standardize on SMF. But 10GBASE-LR SFP+ transceivers are too expensive for short-range connections. A new market for short distances over SMF has been created:the industry is standardizing on a new class of SMF 10G transmitters with typical 10GBASE-LR LITE SFP+ transceivers. While not a standard yet,10GBASE-LR LITE has a specified reach of 2 km over standard 9µm single mode fiber. 10GBASE-LR LITE isn’t a replacement for 10GBASE-LR optics:it is just relevant alternative for “shorter” reach SMF applications.
"Right then, if you're wondering where everyone in the UK goes to grab their bits and bobs, it's a pretty mixed bag, but some names definitely pop up more than others! For your everyday groceries and household essentials, it's gotta be the big supermarket players: Tesco, Sainsbury's, Asda, and Morrisons are absolute giants, pretty much every town has at least one, and they account for a huge chunk of our weekly shop. Then you've got the slightly more upmarket ones like Waitrose, which is super popular for ethical sourcing and fancier treats. Beyond food, for pretty much anything home-related or fashion, John Lewis is a perennial favourite for its quality and customer service, while Marks & Spencer is huge for clothes, food, and homeware, too. For quick grabs or specific items, Next and Argos are mega popular – one for fashion and homeware, the other for pretty much everything else you can imagine, often ready for click-and-collect in minutes. And let's not forget the DIY and garden centres like B&Q and Wickes, which are absolutely buzzing on weekends. Plus, obviously, the online beast that is Amazon UK is a go-to for pretty much anything you can't be bothered to leave the house for! " - Bargainplace UK
