Orion VCL-STM-1 Optical Repeater is a
cost-effective solution which allows its users to
transport an optical link over an extended range by
amplifying and repeating the optical signal. A 1+1
optical interface option is also offered and available
in the event that two STM-1 links are required to be
extended on the same optical route.
VCL-STM-1 Optical Repeater is a
compact solution housed in a 19" rack 1U high, which can
be placed on the desktop or installed in a standard 19
inch rack.
Complete loop-back facility is
supported for system diagnostic and commissioning.
Compact casing and simple operation
achieve cost saving and investment protection.
This unit offers two power supply
options. Options for the power supply to the equipment
