25Gb/s SFP28 CWDM 10km Fiber Channel Transceiver Module

HTF' HTSC-FLxx11x 25Gb/s SFP28 transceiver muaj tsib ntu: tus neeg tsav tsheb LD, lub limiting amplifier, digital diagnostic monitor, CWDM DFB laser thiab PIN photo-detector .Cov ntaub ntawv module txuas mus txog 1{{18} }km hauv 9/125um ib hom fiber ntau. Lub module kho qhov muag kev twb kev txuas yog duplex LC thiab yuav tsum tau sib xws nrog SFP ntxiv rau 28Gbps thiab rov qab sib xws nrog legacy 10G SFP ntxiv pluggable. SFP28 CWDM LR module yog ib qho khoom siv kev taw qhia dual nrog lub transmitter thiab receiver ntxiv rau kev tswj hwm kev sib txuas (2-wire interface) hauv tib lub cev pob. 2-wire interface yog siv rau serial ID, digital diagnostics thiab module tswj muaj nuj nqi. Lub transmitter hloov 25Gbit / s serial PECL lossis CML cov ntaub ntawv hluav taws xob rau hauv cov ntaub ntawv kho qhov muag raws li 25GBASE-LR tus qauv. Ib qho qhib collector tau tshaj Transmit Disable (Tx_Dis) yog muab. Logic "1" lossis tsis muaj kev sib txuas ntawm tus pin no yuav lov tes taw lub laser los ntawm kev xa tawm. Logic "0" ntawm tus pin no muab kev ua haujlwm ib txwm muaj. Lub transmitter muaj lub tshuab hluav taws xob tsis siv neeg tswj lub voj voog (APC) kom ntseeg tau tias lub zog kho qhov muag tsis tu ncua hla cov khoom siv hluav taws xob thiab qhov kub thiab txias. Ib qho qhib collector tshaj Transmit Fault (Tx{19}}Fault) yog muab. TX_Fault is module output contact that when high, shows that the module transmitter has detected a fault condition related to laser operation or safety. TX_Txoj kev sib cuag tawm tsis raug yog qhov qhib qhov dej tawm / sau thiab yuav tsum rub mus rau Vcc_Tus tswv tsev nrog lub resistor hauv thaj tsam 4.7-10 kΩ. TX_Disable is a module input contact. Thaum TX_Disable tau lees tias siab lossis qhib sab laug, SFP28 module transmitter tso zis yuav raug muab tua. Qhov kev sib cuag no yuav tsum rub mus rau VccT nrog 4.7 kΩ rau 10 kΩ resistorThe receiver converts 25Gbit / s serial optical data rau hauv serial PECL / CML cov ntaub ntawv hluav taws xob. Ib qho qhib collector tshaj Loss of Signal yog muab. Rx_LOS thaum siab qhia txog qib teeb pom kev kho qhov muag hauv qab uas tau teev tseg hauv tus qauv cuam tshuam. Rx_LOS tiv tauj yog qhov qhib qhov tso tawm / sau tawm thiab yuav tsum tau rub mus rau Vcc_Tus tswv tsev nrog cov resistor hauv thaj tsam 4.7-10 kΩ, lossis nrog ib qho active kev txiav txim. Fais fab mov filtering yog pom zoo rau ob qho tib si transmitter thiab receiver. Rx_LOS teeb liab yog tsim los ua qhov qhia ua ntej rau lub kaw lus uas SFP28 tau teeb tsa tias lub teeb liab tau txais lub zog qis dua qhov tau teev tseg. Xws li ib qho kev qhia feem ntau yog taw qhia rau cov xov tooj uas tsis tau teeb tsa, cov kab hluav taws xob tawg, lossis cov neeg xiam oob khab, tsis ua haujlwm lossis lub tshuab hluav taws xob tawm ntawm qhov kawg ntawm lub cable.
