DEV 3550
MODULO Optical Upstream Receiver
The MODULO Optical UpstreamUpstream, describe the transmission of an RF signal from the subscriber to the headend or hub site. Receiver DEV 3550 is an active module within the MODULO HFCHybrid fiber-coaxial (HFC) is a telecommunications industry term for a broadband network that combines optical fiber and coaxial cable. product portfolio to be used in a MODULO frame. It meets the needs of the upcoming necessities in HFCHybrid fiber-coaxial (HFC) is a telecommunications industry term for a broadband network that combines optical fiber and coaxial cable. Headends as it provides High Linearity, electronically adjustable GainGain is defined as the ratio of the output power to the input power in dB. If a device provides gain the input signal will be amplified (gained) and thereof the output signal amplitude is typically higher than the one of the incoming signal.
, and an electronically adjustable Equalizer. The Optical UpstreamUpstream, describe the transmission of an RF signal from the subscriber to the headend or hub site. Receiver supports a wideband input range of 1260...1610 nm. All active MODULO modules fully support DOCSISData Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access.3.1 regarding frequency range, Noise Immunity & Radiated Disturbance. A Monitor Port (20 dBdB is a logarithmic unit used to describe a ratio, here usually of power. Tap built with a Directional Coupler) allows to easily analyse the signal quality.
