6.0 版本的功能让新用户和当前 OptiFiber Pro 用户都能受益

You’ve probably heard of the new OptiFiber Pro HDR models we recently introduced, which are designed for OSP and PON applications. However, there are a number of new features now available as part of this launch that work in both the current OptiFiber Pro as well as the new HDR models. In fact, these new features can be added to any existing OptiFiber Pro at no charge through a simple upgrade. Let’s check out these new capabilities.

New OptiFiber Pro High Dynamic Range Modules for Outside Plant and Passive Optical Networks

凭借全新的 Fluke Networks OptiFiber® Pro 高动态范围 (HDR) 光时域反射计,Versiv 成为满足从 FTTx、PON 和数据中心到类级结构化布线各种应用要求的单一解决方案。Since Versiv users report that its efficient and familiar interface cuts costs by 65% when testing, certifying and maintaining copper and fiber network installations, it’s clear why they’d want to apply the same savings to outside plant jobs as well.

It’s That Time of Year Again – Beware of Ghosts and Dead Zones!

There’s a chill in the air, leaves are falling and it’s time for all things spooky. So we thought that in the spirit of Halloween, we would post this blog again that takes a look at two of the most confusing (and perhaps scariest) OTDR events--ghosts and dead zones.

Type 3 and Type 4 are Here!

Last week the IEEE 802.3bt standard for Type 3 and Type 4 PoE was finally ratified! While we’ve been talking about these higher levels of PoE for quite some time, now that they are finally an approved standard, we thought it was a good time to clear the air on PoE types, classes, and certification, as well as provide a refresher on our specialty—testing.

Mixed Mindfulness

When it comes to a cabling infrastructure, not all media and applications are always the same. So for each and every link, it’s important to be aware of what you’re testing—from both a media type and application standpoint.

The A-B-C’s of Fiber Polarity

Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, it's The A-B-C’s of Fiber Polarity

To properly send data via light signals, a fiber optic link’s transmit signal (Tx) at one end of the cable must match the corresponding receiver (Rx) at the other end.

While this seems obvious, polarity is one area that seems to cause the most confusion among technicians. So let’s break it down and start at the beginning.
