High speed applications are driving the deployment of multifiber MPO/MTP architectures in the data center, and it’s not just cloud and hyperscale data centers that are deploying these solutions. As the de facto interface for 40 Gig and 100 Gig switch-to-switch backbone data center applications that use parallel optics, MPO/MTP links are rapidly becoming commonplace in today’s enterprise data centers.

A passive optical LAN, also sometimes referred to as simply a passive optical network (PON), is a point-to-multipoint architecture that used passive optical splitters to split optical transmission signals from a single strand of singlemode fiber into multiple outputs. The technology has gained wide acceptance in outside plant applications, and it is now gaining traction in premise applications—especially in government and hospitality markets.
Driven by the NBASE-T Alliance and compatible with the NBASE-T specification, IEEE 802.3bz specifies 2.5 Gbps over 100 meters of Category 5e cabling or 5 Gbps over 100 meters of Category 6 cabling. It also includes support for 5 Gbps over Category 5e on defined use cases (extended frequencies).
광케이블을 통해 제대로 데이터를 보내려면 케이블의 한쪽 끝에 있는 링크의 전송 신호(Tx)가 다른 쪽 끝에 있는 해당 수신기(Rx)와 일치해야 합니다. 또한 신호가 흐르는 방향을 결정하는 극성의 역할은 이러한 일치가 유지되도록 하는 것입니다. 광케이블 극성은 업계에서 많은 혼란을 야기하는 듯한 영역이며, 특히 병렬 광케이블 애플리케이션에 다중 광케이블 MPO 솔루션이 사용되었을 때 그렇습니다.
At this time of year, every industry tends to reflect on the past twelve months and make predictions about what 2018 will bring – it’s just what we do. So why should this year be any different?
In the spirit of the season and that “Sound of Music” favorite by Julie Andrews (that some have dubbed a holiday classic), we thought we’d take a moment to wish everyone Happy Holidays and Best Wishes for a Prosperous New Year and share with you a recap of some of this years’ favorite Cabling Chronicles (yes, it is sung to the tune of “My Favorite Things.”)
There’s no doubt that the European Union has a lot of rules and regulations—something frequently pointed out by those who campaigned for a Brexit vote in the United Kingdom. And many joke about some of the more ridiculous ones, like the law that prohibits people from eating pet horses, or the one that prohibits manufacturers of bottled water from labels suggesting that consumption could fight dehydration. (Since when didn’t water fight dehydration?)
A fusion splice is when two fibers are fused together using an electric arc. Often used with pigtails for connecting 250-micron outside plant fiber to 900-micron inside plant fiber at the building entrance, fusion splicing is achieved with a fusion splicing machine after the fiber is properly cleaved with a precision cleaver. Fusion splicing can be done for a single fiber or for 12-fiber ribbon cable via mass fusion splicing that splices all 12 fibers at once.
The much-anticipated higher levels of PoE have been quite the buzz in the industry. Now that the 802.3bt standard for PoE that includes Type 3 and Type 4 PoE is expected to be ratified early next year, we will start to see more devices forego their AC power connection for PoE.
While you might hear your CFO grumbling about staying under budget from a dollar perspective, staying under your loss budget from a fiber perspective has a much bigger impact on your network performance – which ultimately impacts your bottom line by avoiding downtime.
But how exactly is your loss budget defined and how do you ensure you don’t exceed it?
