General Features
The receiver section for the HFCT-5701L/LP contains
an InGaAs/InP photo detector and a preamplifier
mounted in an optical subassembly. This optical
subassembly is coupled to a post amplifier/decision
circuit on a circuit board. The design of the optical
subassembly is such that it provides better than 12 dB
Optical Return Loss (ORL).
The HFCT-5701L/LP is complaint to 1 GbE and 1G FC
specifications. 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.
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
specification by achieving compliance over 2 m to 10
km. The MM link type is expected to meet the 62.5 µm
MMF specification when used with an “offset launch”
fiber.
The optical connector is LC duplex.
SFP MSA Compliance
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.
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.

Operating Temperature
The HFCT-5701L/LP has an operating case temperature
of -10 to +85 °C .
Serial Identification (EEPROM)
The HFCT-5701L/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-5701L/LP serial ID
memory are defined in Table 3.
Eye Safety
For details of product compliance, see Table 1.
Delatch Mechanism
The delatching mechanism uses the same design as
the MM HFBR-5701L. The HFCT-5701L/LP is designed
with an MSA complaint standard delatch as well as an
optional bail wire delatch. The bail wire delatch has
been slightly modified outside 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-5701L/LP can withstand an injection of PSN on
the V
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.
Regulatory Compliance
The product meets all of the regulatory compliance
listed in Table 1.
