    The HTR6001X series transceiver is a high performance module for single fiber
    communications using a 1310nm burst- mode transmitter and a 1490nm continuous-mode
    receiver. It is used in the optical network terminal (ONT) for GPON ONU Class B+ applications
    with Mac inside.
    The Transmitter is designed for single mode fiber and operates at a nominal wavelength
    of 1310nm. The transmitter module uses a DFB laser diode with full IEC825 and CDRH class 1
    eye safety.
    The receiver section uses a hermetic packaged APD-TIA (APD with trans-impedance amplifier) and
    a limiting amplifier. The APD converts optical power into electrical current and the current is
    V1.0  page 2 of 10
    transformed to voltage by the trans-impedance amplifier. The differential DATA and /DATA CML data
    signals are produced by the limiting amplifier.
    An enhanced Digital Diagnostic Monitoring Interface has been incorporated into the
    transceivers. It allows real time access to the transceiver operating parameters such as transceiver
    temperature, laser bias current, burst mode transmitted optical power, received optical power and
    transceiver supply voltage by reading a built-in memory with I2C interface.



    Gigabit-capable Passive Optical Networks (GPON)
    ● HTR6001X is a MSA-compliant SFP that incorporates not just the optics for an ONU, but all of
    the electronics need as well. It is a “PON on a Stick” that an entire FTTH ONU in a slightly
    oversized SFP. It can be plugged into networking equipment. Allowing the data interfaces on a
    switch, router, PBX, etc. to be customized for different fiber environments and distance
    ● The HTR6001X is designed as dual-mode ONU stick, it also supports the EPON ONU OAM. It
    can be applied both on EPON system and on the GPON system .It will automatically establish
    an EPON link with the EPON OLT or GPON link with the GPON OLT.
