Product Description
The EOLS-8524-02-X series multi-mode transceiver is small form factor pluggable module for
bi-directional serial optical data communications such as Fiber Channel FC-PH-2 for
200-M5-SN-I and 200-M6-SN-I. 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 850 nm.
The transmitter section uses a Vertical Cavity Surface Emitted Laser (VCSEL) 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 EOLS-8524-02DX series is 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 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 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 4.7K –
10K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 2000mV differential (200 –1000mV single ended) when properly
terminated.
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
Eoptolink Technology Inc., Ltd.

V4.c
SFP Series
power supply filtering is shown below. Inductors with DC resistance of less than 1ohm 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-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with
100Ω 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 400 – 2000mV
(200 – 1000mV single-ended).
EEPROM
The serial interface uses the 2-wire serial CMOS EEPROM protocol defined for the ATMEL
AT24C02/04 family of components. When the serial protocol is activated, the host generates the
serial clock signal (SCL). The positive edge clocks data into those segments of the EEPROM that
are not write protected within the SFP transceiver. The negative edge clocks data from the SFP
transceiver. The serial data signal (SDA) is bi-directional for serial data transfer. The host uses
SDA in conjunction with SCL to mark the start and end of serial protocol activation. The
memories are organized as a series of 8-bit data words that can be addressed individually or
sequentially.
The Module provides diagnostic information about the present operating conditions. The
transceiver generates this diagnostic data by digitization of internal analog signals. Calibration
and alarm/warning threshold data is written during device manufacture. Received power
monitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring and
temperature monitoring all are implemented. If the module is defined as external calibrated, the
diagnostic data are raw A/D values and must be converted to real world units using calibration
constants stored in EEPROM locations 56 – 95 at wire serial bus address A2H. The digital
diagnostic memory map specific data field define as following .For detail EEPROM information,
please refer to the related document of SFF 8472 Rev 9.3.
