Product description
This 1310 nm DFB 10Gbps SFP+ transceiver is designed to transmit and receive optical data over single
mode optical fiber for link length 10km.
The SFP+ 10km module electrical interface is compliant to SFI electrical specifications. The transmitter
input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled. The
module provides differential termination and reduce differential to common mode conversion for quality
signal termination and low EMI. SFI typically operates over 200 mm of improved FR4 material or up to
about 150mmof standard FR4 with one connector.

Notes:
1) Connected directly to TX data input pins. AC coupled thereafter.
2) Or open circuit.
3) Into 100 ohms differential termination.
4) 20 – 80 %.
5) Loss Of Signal is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
6) Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value
applied through the recommended power supply filtering network.

Pin Assignment
Pinout of Connector Block on Host Board
Notes:
1) Circuit ground is internally isolated from chassis ground.
2) T FAULT |
| is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the host board |
if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V.A high output indicates a transmitter fault
caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds.A low output
indicates normal operation. In the low state, the output is pulled to <0.8V.
3) Laser output disabled on T DIS |
| >2.0V or open, enabled on T DIS |
| <0.8V. |
4) Should be pulled up with 4.7kΩ- 10kΩ host board to a voltage between 2.0V and 3.6V. MOD_ABS pulls line low to
indicate module is plugged in.
5) Internally pulled down per SFF-8431 Rev 4.1.
6) LOS is open collector output. It should be pulled up with 4.7kΩ – 10kΩ on host board to a voltage between 2.0V and
3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
Digital Diagnostic Functions
The ES31X-3LCD10 transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1.
The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities,
standard interfaces, manufacturer, and other information.
Additionally, the SFP+ transceivers provide a unique enhanced digital diagnostic monitoring interface, which allows
real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical
power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning
flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial interface at the 8 bit
address 1010000X (A0h).The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so
the originally defined serial ID memory map remains unchanged.
The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller
(DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated,
the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver
into those segments of the E2PROM that are not write-protected. The negative edge clocks data from the SFP transceiver.
The serial data signal (SDA, Mod Def 2) 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.
