FEATURES  
APPLICATIONS  
l Class B+ Optical Line Terminal (OLT) for ITU-T G.984.2  
Gigabit-capable PON  
l Broadband G-PON System  
DESCRIPTION  
l 2.488 Gbps / 1490 nm Continuous-Mode Transmitter  
l 1.244 Gbps / 1310 nm Burst-Mode Receiver with 2R  
Output  
LT-94B73B series is ITU-T G.984.2 Class B+ optical line  
terminal (OLT) for 2.488 Gbps/1490 nm in downstream and  
1.244 Gbps/1310 nm in upstream. The transmitter section uses  
a multiple quantum well 1490 nm DFB laser and is a class 1  
laser compliant according to International Safety Standard  
IEC-60825. The receiver section uses an integrated 1310 nm  
burst-mode detector preamplifier (IDP) mounted in an optical  
header and a burst-mode limiting post-amplifier IC. Unlike  
the conventional BM RX, the RX does not requires reset  
pulse to receive optical data packets with different optical  
power. LVPECL interface is used for differential inputs and  
outputs. A LVTTL logic interface simplifies interface to  
external circuitry.  
l Resetless BM Receiver Design  
l BM RX with 32 Bits Packet-to-packet Guard Time for  
over 15dB Packet Optical Power Difference  
l High Resistance of BM RX to DC Optical Background  
l 0 to 70oC Operating: LT-94B73B-PCG  
l -20 to 85oC Operating: LT-94B73B-PC-AG  
l 2x6 SFF Package with SC/PC Pigtail  
l Single +3.3 V Power Supply  
l RoHS Compliant  
l Transmitter: AC Coupling Input  
l Receiver: DC Coupling Output  
l LVTTL TX Shutdown Input  
LASER SAFETY  
l LVTTL TX Laser Failure Alarm Output  
l Wave Solderable and Aqueous Washable  
l Class 1 Laser International Safety Standard IEC-60825  
Compliant  
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.
