Lub module converts 4 input channels ntawm 25Gb/s hluav taws xob cov ntaub ntawv mus rau 4 raws ntawm LAN WDM kho qhov muag teeb liab thiab ces multiplexes lawv mus rau hauv ib tug channel rau 100Gb/s optical kis tau tus mob.
- Product Introduction
Cov khoom no yog 100Gb/s transceiver module tsim los rau kev sib txuas lus kho qhov muag daim ntawv thov raws li 100GBASE-LR4 ntawm IEEE P802.3ba thiab OTU4 4I1-9D1F tus qauv. Lub module converts 4 input channels ntawm 25Gb/s hluav taws xob cov ntaub ntawv mus rau 4 raws ntawm LAN WDM kho qhov muag teeb liab thiab ces multiplexes lawv mus rau hauv ib tug channel rau 100Gb/s optical kis tau tus mob. Rov qab ntawm lub receiver sab, lub module de-multiplexes 100Gb / s optical input rau hauv 4 raws ntawm LAN WDM optical signals thiab tom qab ntawd hloov mus rau 4 qhov tso zis ntawm cov ntaub ntawv hluav taws xob.
Lub hauv paus wavelengths ntawm 4 LAN WDM channels yog 1295.56, 1300.05, 1304.58 thiab 1309.14 nm raws li cov tswv cuab ntawm LAN WDM wavelength kab sib chaws txhais hauv IEEE 802.3ba. Cov kev ua haujlwm siab txias LAN WDM DFB transmitters thiab siab rhiab heev PIN receivers muab kev ua tau zoo tshaj plaws rau 100Gigabit Ethernet daim ntaub ntawv mus txog 10km txuas thiab ua raws li kev sib txuas kho qhov muag nrog IEEE802.3ba Clause 88 100GBASE-LR4 cov cai.
Cov khoom lag luam yog tsim los nrog cov qauv tsim, kev sib txuas kho qhov muag / hluav taws xob thiab digital diagnostic interface raws li QSFP + Multi-Source Agreement (MSA). Nws tau raug tsim los ua kom tau raws li qhov kev ua haujlwm hnyav tshaj plaws nrog rau qhov kub thiab txias, av noo thiab EMI cuam tshuam.

QSFP 100G LR4 Functional Description
Lub transceiver module tau txais 4 raws ntawm 25Gb / s cov ntaub ntawv hluav taws xob, uas tau ua tiav los ntawm 4-channel Clock thiab Data Recovery (CDR) IC uas kho dua tshiab thiab txo qhov jitter ntawm txhua lub teeb liab hluav taws xob. Tom qab ntawd, txhua tus ntawm 4 DML laser tsav tsheb IC's converts ib qho ntawm 4 channel ntawm hluav taws xob cov teeb liab mus rau lub teeb liab kho qhov muag uas kis tau los ntawm ib qho ntawm 4 txias DML lasers uas tau ntim rau hauv Transmitter Optical Sub- Assembly (TOSA). Txhua lub laser xa tawm cov teeb liab kho qhov muag hauv qhov tshwj xeeb wavelength teev nyob rau hauv IEEE802.3ba 100GBASE-LR4 cov cai. Cov 4- txoj kab kev kho qhov muag yuav raug kho qhov muag ntau rau hauv ib qho fiber ntau los ntawm 4-rau-1 kho qhov muag WDM MUX. Lub optical tso zis hwj chim ntawm txhua channel yog khaws cia tas li
los ntawm kev tswj fais fab tsis siv neeg (APC) Circuit Court. Lub transmitter tso zis yuav raug muab tua los ntawm TX_DIS hardware teeb liab thiab/los yog 2-wire serial interface.
Tus neeg txais tau txais 4- txoj kab LAN WDM kho qhov muag teeb liab. Cov teeb liab kho qhov muag yog de-multiplexed los ntawm ib tug 1- rau -4 kho qhov muag DEMUX thiab txhua qhov tshwm sim 4 raws ntawm cov teeb liab kho qhov muag raug pub rau hauv ib qho ntawm 4 receivers uas tau ntim rau hauv Receiver Optical Sub-Assembly (ROSA). Txhua tus txais yuav hloov cov teeb liab kho qhov muag mus rau lub teeb liab hluav taws xob. Cov teeb liab hluav taws xob rov ua dua tshiab yog retimed thiab de-jittered thiab nthuav dav los ntawm RX feem ntawm 4-channel CDR. Lub sijhawm rov ua dua 4- txoj kab hluav taws xob tawm hluav taws xob yog ua raws li IEEE CAUI-4 cov kev xav tau ntawm kev sib txuas. Tsis tas li ntawd, txhua qhov tau txais cov teeb liab kho qhov muag raug saib xyuas los ntawm DOM seem. Tus nqi saib xyuas tau tshaj tawm los ntawm 2-wire serial interface. Yog tias ib lossis ntau qhov tau txais cov teeb liab kho qhov muag tsis muaj zog dua li theem pib, RX_LOS kho vajtse tswb yuav tshwm sim.
Ib qho +3.3V fais fab mov yuav tsum tau siv los txhawb cov khoom no. Ob lub hwj chim mov pins VccTx thiab VccRx yog txuas nrog sab hauv thiab yuav tsum tau siv ib txhij. Raws li MSA specifications lub module muaj 7 tsis tshua muaj zog kho vajtse tswj pins (suav nrog rau cov 2-wire serial interface): ModSelL, SCL, SDA, ResetL, LPMode, ModPrsL thiab IntL.
Module Xaiv (ModSelL) yog tus pin input. Thaum tuav qis los ntawm tus tswv tsev, cov khoom no teb rau 2-wire serial lus txib. Lub ModSelL tso cai rau kev siv cov khoom no ntawm ib qho 2-wire interface tsheb npav - tus kheej ModSelL kab yuav tsum tau siv.
Serial Clock (SCL) thiab Serial Data (SDA) yuav tsum muaj rau 2-wire serial bus kev sib txuas lus interface thiab ua kom tus tswv tsev nkag mus rau QSFP28 nco daim ntawv qhia.
Lub ResetL tus pin ua kom rov pib ua tiav, rov qab cov chaw rau lawv lub xeev qub, thaum qib qis ntawm ResetL tus pin tau tuav ntev dua li qhov tsawg kawg nkaus mem tes ntev. Thaum lub sijhawm ua tiav ntawm kev rov pib dua tus tswv tsev yuav tsum tsis saib xyuas txhua qhov xwm txheej kom txog rau thaum nws qhia tias ua tiav ntawm qhov rov pib cuam tshuam. Cov khoom lag luam qhia qhov no los ntawm kev tshaj tawm IntL (Interrupt) teeb liab nrog cov ntaub ntawv _Tsis yog_Npaj me ntsis negated hauv daim ntawv qhia nco. Nco ntsoov tias ntawm lub zog nce (nrog rau qhov kub ntxig) lub module yuav tsum tshaj tawm qhov ua tiav ntawm kev rov pib cuam tshuam yam tsis tas yuav tsum tau teeb tsa.
Low Power Mode (LPMode) tus pin yog siv los ua TX lov tes taw. Yog tias tus pin LPMode nyob rau hauv lub xeev siab, lub modulor yuav qhib lub Laser.
Module Present (Mod PrsL) yog lub teeb liab hauv zos rau lub rooj tsav xwm lub rooj tsavxwm uas, thaum tsis muaj khoom, feem ntau rub mus rau tus tswv Vcc. Thaum cov khoom tau muab tso rau hauv lub connector, nws ua tiav txoj kev mus rau hauv av los ntawm ib tug resistor ntawm lub party board thiab asserts lub teeb liab. ModPrsL tom qab ntawd qhia nws tam sim no los ntawm kev teeb tsa ModPrsL mus rau lub xeev "Low".
Interrupt (IntL) tus pin yog siv raws li RX-LOS. Thaum "Low", nws qhia txog RX-LOS kev lees paub. Lwm lub tswb ceeb toom tsis mus txawm tias IntL tus pin.
