DEV 3501
MODULO Optical Downstream Transmitter
The MODULO Optical DownstreamDownstream, describe the transmission of an RF signal from headend or hub site to the subscriber. Transmitter DEV 3501 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 gain.
The Optical DownstreamDownstream, describe the transmission of an RF signal from headend or hub site to the subscriber. Transmitter supports 1310 nm and is available with 7, 10, and 13 dBmdBm or decibel-milliwatt is an electrical power unit in decibels (dB), referenced to 1 milliwatt (mW). optical output power.
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 RangeFrequency Range is the bandwidth for which a device is designed and designated to be used for.

Features

  • Module 2.5 RU; 2 Slots
  • Two RF Input Ports (Combiner) at the Rear
  • RF Monitor Port at the Front
  • Optical Output Connector at the Front (SC/APCThe SC/APC Connector is an optical connector 8° angled originally developed by a NTT using a push-pull mechanism. , optional FC/APCThe FC/APC Connector is an optical connector 8° angled originally developed by a NTT using a screw connection. This connector is often used in military application. or E2000/HRL)
  • 7, 10, or 13 dBmdBm or decibel-milliwatt is an electrical power unit in decibels (dB), referenced to 1 milliwatt (mW). optical Output Power
  • Adjustable MGCMGC (Manual Gain Control) is used to manually adjust the gain. and AGCAutomatic Gain Control (AGC), automatic adjustment of gain to achieve a stable output signal level. for an optimized OMIOMI stands for Optical Modulation Index - It is a variable in the determination of the carrier power and thus the carrier-to-noise ratio (CNR). This is a major factor in the performance of optical communication systems. OMI indicates how much the modulation signal affects light output and is measured in percent.
  • Noise Immunity & Radiated Disturbance in accordance to EN 50083-2
Benefits

  • Space saving installation; up to 18 modules in 5 RU
  • Future proof as it fully supports 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
  • Broadcast and Narrowcast signals can be combined and transmitted over Glass with only one module
  • Monitor Port (20 dBdB is a logarithmic unit used to describe a ratio, here usually of power. tap built with a directional coupler) allows easy access to analyze the signal quality
