Product Description
The DC1xx0-SFP-LC.S40 series single mode transceiver is small form factor pluggable module
for serial optical data communications such as SONET OC-3 / SDH STM-1 and Fast Ethernet. It
is with the SFP 20-pin connector to allow hot plug capability. This module is designed for single
mode fiber and operates at a nominal wavelength of CWDM. There are eighteen center
wavelengths available from 1270nm to 1610nm, with each step 20nm.
The transmitter section uses a multiple quantum well CWDM DFB laser and is a class 1 laser
compliant according to International Safety Standard IEC-60825. The receiver section uses anintegrated InGaAs avalanche photodiode preamplifier (IDP) mounted in an optical header and alimiting post-amplifier IC.
The DC1xx0-SFP-LC.S40 series are designed to be compliant with SFF-8472.

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 theserial clock signal (SCL). The positive edge clocks data into those segments of the EEPROM thatare 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 orsequentially.
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 powermonitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring andtemperature monitoring all are implemented. If the module is defined as external calibrated, thediagnostic 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.
