PPPPrrrroooodddduuuucccctttt DDDDeeeessssccccrrrriiiippppttttiiiioooonnnnThe LBX-GS3SX0035 series transceivers are high performance modules for duplex video transmission application over single mode fiber. These transceivers are designed to transmit/receive data rates from 270Mbps to 2.97Gbps, which are compliant with the following standards:
The transmitter section of LBX-GS3SX0035 is a Class 1 Laser compliant with FDA Radiation Performance Standards, 21 CFR Subchapter J, which is also Class 1 Laser compliant according to International Safety Standard IEC60825. With an internal facing angle polished fiber stub, standard single mode optical patch cord with Standard Polished Connector (SPC) is required.
The receiver section of LBX-GS3SX0035 is provided with an internal facing angle polished fiber stub. Standard single mode optical patch cord with Standard Polished Connector (SPC) is required.
The LBX-GS3SX0035 transceiver is hot pluggable with the SFP 20-pin connector.
The LBX-GS3SX0035 transceiver provides extensive operational status monitoring through an I2C interface.

The host board is required to provide a regulated/filtered power supply of 3.3 +/- 5% V for the LBX-GS3SX0035 via the on board SFP connector. The following figure shows the recommended board supply filtering.
The serial interface uses the 2-wire serial CMOS EEPROM protocol defined for the ATMELAT24C02/04 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 writing 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 usesSDA in conjunction with SCL to mark the start and end of serial protocol activation. The memoriesare 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. Thetransceiver generates this diagnostic data by digitization of internal analog signals. Calibration andalarm/warning threshold data is written during device manufacture. Received power monitoring,transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperaturemonitoring all are implemented. The digital diagnostic memory map specific data field defined asfollowing.
