  • Do you use LED or laser sources?


  • Although lasers are more expensive than LEDs, IDEAL chose to use a VCSEL laser in its 850-nm Multimode adapter. The VCSEL laser is the same 850-nm light source used in Gigabit Ethernet and allows testing of fiber that will support Gigabit Ethernet. Fabry-Perot lasers are used are used in 1300 Multimode, 1310 Singlemode and 1550 Singlemode adapters.
