DESCRIPTION
NU-73H74H is a transceiver for the optical network unit
(ONU) of GE-PON with 1.25Gbps in downstream and 1.25
Gbps in upstream. The NU-73H74H is high performance
module for single fiber communications by using 1310 nm
burst-mode transmitter and 1490 nm continuous-mode
receiver. The receiver section is equipped with
3W-TRX
TM
to
reject incoming high power 1550 nm video signal, where the
rejection ratio is over 40 dB. The transmitter section uses a
multiple quantum well 1310 nm laser and is a class 1 laser
compliant according to International Safety Standard
IEC-60825. The receiver section uses an integrated 1490 nm
detector preamplifier (IDP) mounted in an optical header and a
limiting post-amplifier IC. LVPECL interface is used for
differential inputs and outputs. A LVTTL logic interface
simplifies interface to external circuitry.
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It
complies with IEC-60825 and FDA 21 CFR 1040.10 and
1040.11. The transceiver must be operated within the
specified temperature and voltage limits. The optical ports of
the module shall be terminated with an optical connector or
with a dust plug.
