1. GENERAL DESCRIPTION

This10GigabitSFP+BiDitransceiverisdesignedtotransmitandreceiveopticaldata oversinglemodeopticalfiberforlength20km.

TheSFP+BiDimoduleelectricalinterfaceiscomplianttoSFIelectricalspecifications. Thetransmitterinputandreceiveroutputimpedanceis100Ohmsdifferential.Data linesareinternally AC coupled.  The module provides differential termination and reduce differential to common mode conversion for quality signal termination and lowEMI.SFItypicallyoperatesover200mmofimprovedFR4materialoruptoabout 150mmofstandardFR4withoneconnector.

Thetransmitterconverts10Gbit/sserialPECLorCMLelectricaldataintoserialoptical data compliant with the 10GBASE-LR standard.  An open collector compatible TransmitDisable(Tx_Dis)isprovided.Logic“1”ornoconnectiononthispinwill disable the laser from transmitting.Logic“0” on this pin provides normal operation.The transmitterhasaninternal automatic power control loop (APC) to ensure constant optical power output across supply voltage and temperature variations.Anopencollector compatible Transmit Fault (Tx_Fault) is provided. TX_Fault is module output contact that when high, indicates that the module transmitter hasdetectedafaultcondition related to laseroperationorsafety.The TX_Fault output contact is an opendrain/collector and shall be pulled up to the Vcc_Hostinthewitharesistorintherange4.7-10kΩ.TX_Disableisamodule input contact. When TX_Disable is asserted high or left open, the SFP+ module transmitteroutputshallbeturnedoff.ThiscontactshallbepulleduptoVccTwitha 4.7kΩto10kΩresistor

Thereceiverconverts10Gbit/sseriallopticaldattaintoserialPECL/CMLelectricaldata. AnopencollectorcompatibleLossofSignalisprovided.Rx_LOSwhenhighindicates an optical signal level below that specified intherelevant standard.TheRx_LOS contactisanopendrain/collectoroutputandshallbepulleduptoVcc_Hostinthe hostwitharesistor in the range 4.7-10 kΩ, or with an active termination.  Power supplyfilteringisrecommendedforboththetransmitterandreceiver.TheRx_LOS signal is intended as a preliminary indicationtothesystem in  the SFP+ is installed that the received signal strength is below the specified range. Such an indicationtypicallypointstonon-installedcables,brokencables,oradisabled,failing orapoweredofftransmitterthefarendofthecable.
