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.
