Ordering Information & Optical Specifications

Model Number		Fiber Mode	Wavelengths	Optical Power Budget	Maximum Transmission Distance
Transmitter	Receiver	Fiber Mode	Wavelengths	Optical Power Budget	Maximum Transmission Distance
VOS-0020DST	VOS-0020DSR	Single-Mode	1310nm/1550nm	12dB	20km
Note: • The Optical Power Budget data fit Mulit-mode(62.5/125 μm),Single-Mode(9/125 μm). • When using 50/125 μm multimode fiber, subtract 3 dB from the optical power budget. • Optical transmission distance is limited to optical loss of the fiber and any additional loss introduced by connectors, splices and patch panels. • Maximum transmission distance is also limited by fiber bandwidth. • Power adapter is manufactured by third party and is supplied with fitted screw-terminal output cables.Power adapter included (for standalone) US, European, UK or Australian power plug. • Please feel free to consult factory for any special requirement and customisation
