Was ist der Unterschied zwischen einer Vorlauffaser und einer Nachlauffaser?

Grundsätzlich gibt es keinen Unterschied. Es handelt sich um ein und dasselbe Produkt. Die unterschiedliche Namensgebung nimmt nur Bezug auf die Positionierung in der Messstrecke. Eine Vorlauffaser wird zwischen das OTDR und die eigentliche Messstrecke gesetzt. Eine Nachlauffaser hingegen an das Ende der Messstrecke angeschlossen.

Wofür wird eine Vorlauffaser verwendet?

Eine Vorlauffaser erfüllt mehrere Zwecke. Zuerst einmal überwindet sie die Totzone des OTDRs. Zum anderen reduziert sie die Steckzyklen am empfindlichen Messeingang des OTDRs. Bei mehreren Messungen muss immer nur die eines Vorlauffasern an die neue Strecke gesteckt werden und nicht das OTDR. Das schont den hochsensiblen Messeingang und spart gleichzeitig Kosten, da der Messeingang typischerweise alle 1.000 Steckzyklen überprüft werden sollte.

Welche Länge sollte meine Vorlauffaser haben?

Das kommt ganz auf die Länge der zu vermessenden Strecke an und damit der am OTDR gewählten Pulsbreite. Grundsätzlich kann man sagen, dass mit zunehmender Streckenlänge auch längere Messfasern benötigt werden. Typische Längen sind für Singlemodestrecken 500 m oder 1.000 m und für Multimodestrecken ca. 100 m. Je nach Anwendungszweck machen aber auch kleinere oder größere Strecken Sinn.

Welche Steckerenden sollte ich für meine Vorlauffaser wählen?

Grundsätzlich kann jede Vorlauffaser mit jedem beliebigen Steckertypen ausgestattet werden. Dabei stehen aktuell LC/PC, LC/APC, SC/PC, SC/APC, FC/PC standardmäßig zur Verfügung. Andere Stecker können natürlich auf Anfrage konfektioniert werden. Grundsätzlich sollte eines der beiden Enden immer den Anschlusstypen des OTDRs haben – also bei einem SC/APC Messeingang auch mindestens einen SC/APC Stecker. Der zweite Stecker kann beliebig gewählt werden. Hier macht es Sinn verschiedene Typen zu nehmen, damit möglichst viele verschiedene Strecken vermessen werden können.

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

This Pillow Is A Must Buy!! What Are You Waiting For?
Size: Queen (Pack of 1)
This is, without a doubt, the best pillow I have ever owned. One of my favorite features is the adjustable shredded memory foam fill, which allows you to customize the loft and firmness by adding or removing foam to suit your sleeping preferences. As both a side and back sleeper, I found it incredibly comfortable and supportive. The overall quality is excellent, from the materials used in the pillow itself to the thoughtful packaging. The removable cover is washable, although I personally use a pillowcase to keep it protected. I also appreciated that extra foam is included, making it easy to fine-tune the pillow over time. The difference in my sleep quality was noticeable from the very first night. I’ve been sleeping more comfortably and waking up feeling more rested ever since I started using it. Considering the quality, comfort, and customization options, I believe the $75 price point is well worth it. I am so impressed with this pillow that I plan to purchase another one in the future.
