Optical Communication System
Datasheet
Description
The SFP1G-SX-31 series multi-mode transceiver is small form factor pluggable module for
bi-directional serial optical data communications such as Ethernet and SDH/SONET. It is
with the SFP 20-pin connector to allow hot plug capability. This module is designed for
multi-mode fiber and operates at a nominal wavelength of 1310nm.
The transmitter section uses a multiple quantum well 1310nm laser and is a class 1 laser
compliant according to International Safety Standard IEC 60825. The receiver section
uses an integrated GaAs detector preamplifier (IDP) mounted in an optical header and
a limiting post-amplifier IC. The SFP1G-SX-31 series are designed to be compliant with
SFF-8472 MSA.

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 kinds. Low indicates normal
operation. In 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 KΩ 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 4.7 – 10 KΩ resistor on the host board. The pull-up voltage shall be VccT or VccR .
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 400 and 2000 mV
differential (200 –1000 mV single ended) when properly terminated.
8
Optical Communication System
Datasheet
7. VccR and VccT are the receiver and transmitter power supplies. They are defined as
3.3V ±5% at the SFP connector pin. Maximum supply current is 300mA.
Recommended host board power supply filtering is shown below. Inductors with DC
resistance of less than 1 ohm should be used in order to maintain the required
voltage at the SFP input pin with 3.3V supply voltage.
When the recommended supply-filtering network is used, hot plugging of the SFP
transceiver module will result in an inrush current of no more than 30mA greater than
the steady state value. VccR and VccT may be internally connected within the SFP
transceiver module.
8.TD-/+: TD-/+: These are the differential transmitter inputs. They are AC-coupled,
differential lines with 100Ωdifferential 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 400 – 2000mV (200 – 1000mV single-ended).

Test Center
Only when quality and 100% compatibility is verified and proved do our modules enter
the market. This depends on FS.COM test center which is supported by a variety of
mainstream original brand switches and professional staff. We are proud of this test
center and believe all of these devices worth the investments, because it brings the best
to our customers.
The original switches could be found nowhere but at FS.COM's test center, eg: Juniper
MX960 & EX 4300 series, Cisco Nexus 9396PX & Cisco ASR 9000 Series, HP 5900 Series & HP

Test Assured Program
FS.COM truly understands the value of compatibility and interoperability to each optics.
Every module FS.COM provides must run through programming and an extensive series
of platform diagnostic tests to prove its performance and compatibility. In our test center,
we care of every detail from staff to facilities—professionally trained staff, advanced test
facilities and comprehensive original-brand switches, to ensure our customers to receive
the optics with superior quality.
Our smart data system allows effective
pro duc t man a ge men t and qua li ty
control according to the unique serial
number, properly tracing the order,
shipment and every part.
Our in-house coding facility programs all
of our parts to standard OEM specs for
compatibility on all major vendors and
systems such as Cisco, Juniper, Brocade,
HP, Dell, Arista and so on.
With a comprehensive line of originalbrand switches, we can recreate an
environment and test each optics in
practical application to ensure quality
and distance.
The last test assured step to ensure our
products to be shipped with perfect
package.
