SmartLoop Technology Just Got Smarter and Faster

Tier 2 (OTDR) 試験におけるファイバー・リンクの双方向試験は、保証のために業界標準やほとんどのメーカーで求められるだけでなく、リンク全体の実損失を知る唯一の方法でもあります。それは、ファイバー・コネクターやスプライスのの損失に加え、全体のリンク損失の測定が、試験をどの方向から実施するかによって異なるためです。Testing a fiber link in one direction can give you different results then testing the same fiber link in the opposite direction.  

Testing Fiber with OptiFiber ProOTDR’s loss results are inferred and not actual loss measurements. OTDRs infer  loss based on changes in backscatter and assume that it's the same throughout the link. But that's not always the case. If an attached fiber has less backscatter or more backscatter, the OTDR reports either more loss or less loss. That's why the bi-directional OTDR testing or testing from both ends of the link and averaging the results is required.

両端からテストする多大な時間とコストを考えると、技術者は時間を可能な限り節約するために、一端ですべてのリンクをテストしたからもう一端に移動しようとします。残念ながら、この方法ではうまくいきません。To accurately test a fiber link  in both directions, the launch and tail cords must remain in their initial measurement positions (even the standards say so) during both tests. しかし一端ですべてのリンクをテストしてから、もう一端に移動するのでは、これは可能ではありません。

Bi-Directional Testing with OptiFiber ProTo solve this dilemma, you can test two fibers at the same time and use a loop  to connect the two fibers together. これにより、OTDRを遠端に移動することなく、デュプレックス・リンクの2つのリンクを一度にテストできます。OTDRs like Fluke Networks’ OptiFiber® Pro feature  “SmartLoop” Technology that checks for the presence of the launch, loop and tail fiber when testing a duplex fiber link.

SmartLoopにより、技術者は遠端に複数のループを展開し、近端を離れることなく双方向試験を実施できるため、試験時間を 50% 以上短縮させることができます。

But wait! SmartLoop just got smarter... and faster.

New Instantons Bi-directional Averaging

When performing bi-directional testing, there is still the need to average the two results from both directions--whether using a time savings loop or not. Since its inception, Fluke Networks' SmartLoop technology has enabled downloading the measurements taken from both ends to LinkWare PC management software that performs the bi-directional averaging for each link and provides a final averaged result. While this removes the risk of human error involved with manual bi-directional averaging, it is still an extra step required to get the final result. But not anymore.

Unlike other testers on the market that require using either two OTDRs, , or purchasing an additional option, the OptiFiber Pro now includes on-board bidirectional averaging for that cuts Tier 2 testing time even more!  (If you have an existing OptiFiber® Pro, you can download the free Version 4.6 Build 2 Firmware here. .)

No longer does a technician have to download the results to a PC to get the bi-directional average and final result for the link--the results are instantly averaged right on the tester. Technicians now know if a fiber link passes or fails right when they're done with the bidirectional testing. You can see a video of how it works here. .

With constant pressure to get the job done quicker and done right the first time for maximum profitability, it's good to know that SmartLoop just got smarter.
