Duet Microelectronics Launches New Optical Receiver Modules

Fully Autonomous Optical Receiver Modules Deliver a Constant Output Voltage and RF Output to Support Reliable FTTx Data Throughput

RARITAN, N.J., Feb. 12, 2018 – Duet Microelectronics LLC, an innovative RF semiconductor solutions provider, today introduced a new family of optical receiver modules optimized for fiber to the home (FTTH) / fiber to the premises (FTTP) applications.  Designers and OEMs of FTTx ONTs, HFC optical nodes and mobile consumer premises equipment (CPE) can take advantage of the DTA000x family’s Field-and-ForgetSMpatent-pending ease of use, small landed footprint, and lowest cost per bit delivered performance.=

“We are setting the standard for fiber to the premises optical receiver performance,” said Conrad Young, Marketing Director at Duet Microelectronics.  “The ultra-low noise, wide dynamic range and constant RF output power of our fully autonomous receivers enable equipment manufacturers to provide ultra-high data throughout while reducing external components and design time.  This supports MSOs who seek to deliver a superior experience for users of pure fiber optic networks.”

Duet Microelectronics’ DTA000x wide dynamic range receiver module family has been developed to power SART and CableLabs Data Over Cable Service Interface Specification (DOCSIS®) 3.1 compliant FTTx and HFC networks with unmatched ease of use and bit efficiency.  The DTA0002 offers an optical power input range of +3 to -15 dBm with an RF output power of +23 dBmv per channel.  The DTA0003 offers an optical power input range of 0 to -18 dBm with an RF output power of +15 dBmv per channel.

Duet Microelectronics DTA000x FTTx Optical Receiver Module Family Key Facts and Highlights:

  • Provides Fully Autonomous Current-to-Voltage Transimpedance for FTTx & HFC Optical Receivers
  • Constant Vout and RF Pout as Photo Diode Current Varies (Patent Pending)
  • No Feedback Loop or Voltage Variable Attenuator (VVA) Required
  • EINC ≤ 2.0 pA/Square-Root-Hertz (@ 87 to 1000 MHz, -15 dBm Optical Input Power)
  • Constant Cascadable RF Output over -15 to +3 dBm Optical Input Power
  • 75-Ohm Differential RF Output (Single-Ended Optional)
  • User Adjustable Current versus Linearity (+5 Vdc @ 185 mA improves MER to > 40 dB)
  • Compliant to State Administration of Radio and Television (SART) FTTH/HFC Optical Link Standards
  • Reduce Landed Bill of Material (BOM) External SMT Parts Count by 10X or More Compared with Alternatives
