A number of choices are available for lasers in ViaLite products. The standard DFB laser provides excellent performance for most applications. However high power and dual isolated lasers are available for high performance applications. Also, WDM and CWDM lasers are available for applications where mup to 18 channels are multiplexed down a single fiber.
Distributed feedback (DFB) lasers
ViaLiteHD fiber optic links use distributed feedback (DFB) lasers.
Dual isolated lasers
Dual isolated lasers are suited for systems which are susceptible to reflections, e.g. systems which use flat (AFC) optical connectors as opposed to angled (APC) connectors.
High power lasers
High power lasers allow for greater distances and increased dynamic range. These are intended for applications where signals are weak or vary widely in strength (for example due to weather conditions).
WDM and CWDM lasers
WDM and CWDM lasers offer multiple channels to be transmitted using only a single fiber. WDM and CWDM equipped rack chassis cards and modules operate together with ViaLite multiplexers. The two channel WDM duplexers are available in either pigtail or chassis card format allowing integration with larger systems or to be rack mounted in a ViaLite chassis with other ViaLite modules. The multi-channel CWDM systems are available in 1RU high 19″ rack format and support multiplexing of up to 18 channels per fiber.
