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.

101 系列：What is an APC Connector and How Do I Test It?
The singlemode fiber connectors you likely encounter the most feature a blue connector body, but if you’re working with any passive optical networks (PONs), carrier networks or large cloud/colo or hyperscale data centers, you may encounter singlemode fiber connectors with a green connector body – and these green connectors are growing in popularity.

Type 3 and Type 4 are Here!

Wire Map Testing: It’s Not All About Color
Virtually every Ethernet cable tester can perform a wire map test - likely the most basic test for copper network cabling. Despite being a basic test, it is actually one of the most critical. And while the pair colors of blue, orange, green and brown might help you pass wire map testing, the test itself really doesn’t care about color at all.
Let’s take a closer look.
