fiber

I've heard that there are compatibility problems when using 50um fiber with some fiber converters. After some research I'm thinking this is a legacy issue when using slower devices (100 Base FX) that used LEDs. I was told that the fiber converters are made for a certain size of fiber core and wont work with 50um fiber. Am I right in thinking this is just a corporate knowledge thing that is outdated when using 1000 Base SX converters (which should be using lasers instead of LEDs)?

Can someone purchase a dedicated fiber switch that does not have copper ethernet… >>> More

Unhappy with performance of GBit Ethernet to Fiber converter

I just bought a TP-Link MC200CM GBit Ethernet (1000-T) to Fiber (1000-SX) media converter. The device works but I'm unhappy with the performance: When connecting my computer over 1000-T (twisted pair, Cat 6, 18meters) with my server, I get a throughput of about 610MBit/s. If I replace the cable with… >>> More
