Product Description
The DGxx-SFP-LC.S80 series single mode transceiver is small form factor pluggable module forduplex optical data communications. This module is designed for single mode fiber and operates
at a nominal DWDM wavelength from 1528.77nm to 1565.50nm as specified by the ITU-T. It is
designed to deploy in the DWDM networking equipment in metropolitan access and core
networks.
It is with the SFP 20-pin connector to allow hot plug capability. The transmitter section uses aDWDM multiple quantum well EML laser and is a class 1 laser compliant according toInternational Safety Standard IEC-60825.
The DGxx-SFP-LC.S80 Series are designed to be compliant with SFF-8472 Multi-Source
Agreement (MSA).

EEPROMThe 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 SFPtransceiver. 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.
