Ua haujlwm nrog: 850nm vcsels
Kev nrug deb:
OM3 (50μm): 100M @ 10GBPS, 70M @ 40GBPS
OM4 (50μm): 150m @ 10GBPPS, 150M @ 40GBPS, 100M @ 100GBps
Om5 (50μm): 150m @ 40GBps, 150m @ 100GBps
Tus nqi: $ 0.30 / meter Cable, $ 30-1 nruab rau ib qho kev txiav
Thaum siv: cov ntaub ntawv chaw luv luv ncav cuag (<300m), lower cost per link
Tsis tuaj yeem sib xyaw:
850nm transiver yuav tsis ua haujlwm nrog ib qho - hom fiber ntau (hom kev tsis sib haum xeeb ua rau kev puas tsuaj)
1310nm transceiver ua haujlwm tsis zoo nrog multimode fiber ntau (tshaj tawm ntau hom, ua rau muaj kev sib cais)
Kev Txiav Txim Tsob Ntoo:
Distance ≤100m AND speed ≤100Gbps → Multimode (OM4) cheaper Distance 100-550m AND speed ≤100Gbps → Either works; consider upgrade plans Distance >550m OR speed >100GBps → ib leeg - hom tsuas yog xaiv
Kev txiav txim siab ntxiv:Ib Leeg - hom fiber ntau ntsia hnub no txhawb nqa:
Tam sim no: 10GBps (SFP + LR)
Yav Tom Ntej: 40GPPS (QSFP + LR4), 100GBPPS (QSFPPS (QSFPPPS (QSFP {} DD Fiber, tsuas yog Swap Transceivers
Cov Fiber ntau muaj cov kev txwv deb uas ntsws nrog txoj kev khiav ceev. OM4 fiber txog 100m ntawm 100gbps yuav tsis txhawb 400GPPS (tsis muaj 400g SR4 tus qauv muaj rau<150m).
Ntau npaum li cas lub zog ua tau cov pa hloov tshiab niaj hnub noj?
Kev noj fais fab hloov pauv hloov pauv los ntawm kev nrawm, ncav cuag, thiab kev hloov kho qauv:
Los ntawm kev nrawm:
1g SFP: 0.5-1w
10G SFP +: 1-1.5W

100g QSFP28: 3.5-4.5W
400g qsfp - DD: 10-14W (txawv heev los ntawm)
800g OSFP: 15 {- 20W (DSP-based), 8-12W (LPO)
1.6T OSFP: 20-25W (nrog 3NM DSP), 12-15W (LPO Projected)
Los ntawm ncav cuag:
Luv -} mus txog (sr,<300m): Lowest power (VCSELs efficient)
Nruab nrab -} mus txog (LR, 2-10KM): Muaj zog ({% rau kev tsis lees paub DFB)
Long-reach (ER, >40km): High Hwjchim (yuav tsum tau TEC, Sophisticated DSP)
Coherent modules:
100G: 6-8W
400G: 12-16W
800g: 18-24W (suav nrog DSP)
