Description
Applicationswww.DataSheet4U.com
The LCP-155 series is a hot pluggable 3.3V z SONET OC-3/SDH STM-1
Small-Form-Factor transceiver module designed z ATM Network
expressly for high-speed communication z Fast Ethernet
applications that require rates of up to
155Mbit/sec. It is compliant with the ATM, SONET
OC-3/SDH STM-1 standards, as well as the
SFF-8472 SFP Multisource Agreement (MSA).
The LCP-155 series are designed to be
z Switch to Switch interface
z Switched backplane applications
z File server interface
Performance
compliant with SFF-8472 SFP Multi-source
Agreement (MSA) with digital diagnostic
monitoring functions: Temperature, VCC, TX
optical power, TX laser bias current, and RX
received optical power.
The post-amplifier of the LCP-155 series also
includes a Loss of Signal (LOS) circuit that
z LCP-155A4HDR Data Link up to 2km in
62.5/125μm in Multi-Mode Fiber
z LCP-155B4JDR Data Link up to 15km in
9/125μm Single Mode Fiber
z LCP-155B4MDR Data Link up to 40km in
9/125μm Single Mode Fiber
provides a TTL logic-high output when the
received optical level is below a preset LOS
Assert threshold.

Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor on the host
board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates a laser fault of some kind.
Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
2) TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module
with a 4.7 – 10 K Ω resistor. Its states are:
Low (0 – 0.8V):
Transmitter on
(>0.8, < 2.0V):
Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open:
Transmitter Disabled
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K – 10KΩresistor on the
host board. The pull-up voltage shall be VccT or VccR (see Section IV for further details). Mod-Def 0 is grounded
by the module to indicate that the module is present Mod-Def 1 is the clock line of two wire serial interface for
serial ID Mod-Def 2 is the data line of two wire serial interface for serial ID
4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor.
Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates the received optical power is
below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In
the low state, the output will be pulled to < 0.8V.
5) VeeR and VeeT may be internally connected within the SFP module.
6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be
terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus
not required on the host board. The voltage swing on these lines will be between 370 and 2000 mV differential
(185 – 1000 mV single ended) when properly terminated.
