850/1300nm Dual Window Coupler/Splitters

Introduction:
Fiberdyne Splitter/Coupler devices are bi-directional. If they are used to combine signals then they are “couplers.” If they are used to divide a signal then they are “splitters.”
Note: Both terms are often used, interchange-ably, to mean the same device. The multimode splitter/coupler, are typically applied to applications which use an “overfilled launch” (OFL). An OFL example is the LED transmitter, typically used in 10Base and 100 Base Ethernet multimode fiber links. An OFL fills the modes of the multimode fiber. These multimode splitter/couplers work best with OFL configurations.
Note: New high-speed, multimode fiber links (e.g.1000 Base-SX) use lasers. Typically, these 850-nm sources are VCSELs (vertical cavity surface emitting lasers). VCSELs do not provide an OFL into multimode fiber; they do not fill the mode-structure of the multimode fiber. For these applications, Fiberdyne recommends their “Laser Multimode” splitter/coupler.

Features:
• - Multimode Dual Window (850/1300nm)
• - Light Duty (250µm)
• - Medium Duty (900µm) or Heavy Duty (3mm Jacket)
• - Packaged Couplers are also available in modules.
