850/1310 MM Gigabit Ethernet Fiber Kit for DSP4000. Networks running Gigabit Ethernet over multimode fiber use a new type of light source called a Vertical Cavity Surface Emitting Laser (VCSEL). A VCSEL is more cost-effective than the conventional laser and provides greater bandwidth than possible with LED light sources. The proper way to accurately test a fiber network using a VCSEL source is with a tester that uses a VCSEL such as the FTA-440S.
