DESCRIPTION
LT-54B33B series is ITU-T G.983.3 Class B optical line
terminal (OLT) for 622 Mbps/1490 nm in downstream and
155 Mbps/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.
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.
