Multimode fiber (MMF) dominates in local area networks and data centers. Electro-optic converters (e.g. transceivers) used for transmitting and receiving data are less expensive than those used for transmitting over single-mode fiber. Network capacity has increased over the years through the use of parallel transmission – using multiple fibers and multiple transceivers. As the need for capacity continues to increase, the use of multiple fibers and multiple transceivers needed for parallel transmission may increase network cost.

Since the development of 40GBASE-T (IEEE 802.3bq) began a few years ago, most of us believed that the next Ethernet data center speed for twisted-pair copper cabling beyond 10 Gb/s would be 40 Gb/s.

How long are the fiber links you need to test? Is it a short 50-meter multimode data center link, a longer 550-meter backbone, or maybe even a 130-kilometer singlemode link?
With contaminated connections remaining the number one cause of insertion loss and back reflection that inhibits optical transmission and causes havoc with expensive transceivers, it’s vital that fiber end-faces at both ends of a link are visually inspected.

You’ve just finished a copper cabling installation for a customer, your DSX-5000 CableAnalyzer is properly configured and you’re ready to start testing. With a press of the “TEST” button, you’re off and running.
Link after link, the tester displays a “Pass” and you’re feeling really good about the quality workmanship of your installation.
