General Features
1000BASE-LX Compliance:
SFP MSA Compliance:
The HFCT-5710L/LP is
compliant with the IEEE 802.3Z
(2000 Edition) Physical Medium
Dependent (PMD) sublayer and
baseband medium, type
1000BASE-LX (Long Wavelength
Laser) description. This includes
specifications for the signal
coding, optical fiber and
connector types, optical and
electrical transmitter
characteristics, optical and
electrical receiver
characteristics, jitter
characteristics, and compliance
testing methodology for the
aforementioned.
The product package is
compliant with the SFP MSA
with the LC connector option.
The SFP MSA includes
specifications for mechanical
packaging and performance as
well as dc, ac and control signal
timing and performance.
This transceiver is capable of
implementing both Single Mode
(SM) and Multimode (MM)
optical fiber applications in that
order of precedence in the event
of conflicting specifications. In
addition, the SM link type
exceeds the 2 m to 5 km
1000BASE-LX specification by
achieving compliance over 2 m to
10 km. The MM link type meets
the 50 µm and 62.5 µm MMF
specification when used with an
“offset launch” fiber.
Operating Temperature
The HFCT-5710L/LP has an
operating case temperature of
-10 to +85°C.
The power supply is 3.3 V dc.
The High Speed I/O (HSIO)
signal interface is a Low Voltage
Differential type. It is ac coupled
and terminated internally to the
module. The internal
termination is a 100 Ohm
differential load.
The optical connector is LC
duplex.
There is no governing
environmental specification in
IEEE 802.3Z therefore the
environmental specifications
contained in this product
definition take precedence.
Compliance over all operating
conditions defined in this
document is implied except
where specifically noted.
1 µH
Serial Identification (EEPROM)
The HFCT-5710L/LP is
compliant with the SFP MSA,
which defines the serial
identification protocol. This
protocol uses the 2-wire serial
CMOS E2PROM protocol of the
ATMEL AT24C01A or similar.
MSA compliant, example
contents of the HFCT-5710L/LP
serial ID memory are defined in
Table 9.
Eye Safety
For details of product
compliance, see Table 1.
De-latch Mechanism
The de-latching mechanism uses
the same design as the MM
HFBR-5710L. The HFCT-5710L/
LP is designed with an MSA
compliant standard de-latch and
an optional de-latch for Belly-toBelly operation. The optional
de-latch has been slightly
modified outside of MSA
compliance to optimize the
mechanical performance of the
product. These modifications do
not interfere with the overall
form, fit and function as
specified by the SFP MSA.
Power Supply Noise
The HFCT-5710L/LP can
withstand an injection of PSN on
the VCC lines of 100 mV ac
without a degradation in eye
mask margin to 10% on the
transmitter and a
1 dB sensitivity penalty on the
receiver. This occurs when the
product is used in conjunction
with the MSA recommended
power supply filter shown in
Figure 1.

Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10K 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 input is used to shut down the laser output per the state table below with an external 4.7 - 10 KW pull-up resistor.
Low (0 - 0.8 V):
Transmitter on
Between (0.8 V and 2.0 V):
Undefined
High (2.0 - 3.465 V):
Transmitter Disabled
Open:
Transmitter Disabled
3. MOD-DEF 0,1,2. These are the module definition pins. They should be pulled up with a 4.7 - 10 KW resistor on the host board to a supply less than
VccT +0.3 V or VccR+0.3 V.
MOD-DEF 0 is grounded by the module to indicate that the module is present
MOD-DEF 1 is clock line of two wire serial interface for optional serial ID
MOD-DEF 2 is data line of two wire serial interface for optional serial ID
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7K - 10 KW resistor on the host board to a supply
< VccT,R+0.3 V. 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 < 0.8 V.
5. RD-/+: These are the differential receiver outputs. They are ac coupled 100W differential lines which should be terminated with 100W 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 1600 mV differential (185 - 800 mV single ended) when properly terminated.
6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.135 - 3.465 V at the SFP connector pin. The maximum supply
current is 300 mA and the associated inrush current will be no more than 30 mA above steady state after 500 nanoseconds.
7. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100W differential termination inside the module. The
ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 500 - 2400 mV (250 1000 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 - 600 mV single ended) be used for best
EMI performance.
