KCO QSFP+ 40G ER4 40Gb/s QSFP+ SMF 1310 Transceiver ea 40km
QSFP+ 40G ER4 KE ENG?
+ EQSFP+ 40G ER4 e ea lumellana. Mojule oa transceiver oa QSFP+ oa 40G o na le lihokelo tsa duplex tsa LC, tse fihlang khokahanong e fihlang ho 10km holim'a faeba ea OS2 ea mode e le 'ngoe (SMF).
+ Transceiver ena ea optical ea fiber ea 40G e tla le sehokelo sa likanale tse 4 tsa QSFP+ tse peli, e nolofalletsang kakaretso ea bandwidth ea 40 Gbps ka kanale ka 'ngoe e nang le sekhahla sa data sa 10 Gbps.
+ Mosebetsi oa DOM/DDM (tlhokomelo ea tlhahlobo ea dijithale) o tšehetsoa ho transceiver ea fiber optic ea 40G ho fihlella tlhokomelo ea liparamente tsa ts'ebetso ea nako ea sebele.
+ Re entse mojule oa 40GBASE-ER4 QSFP+ o latela litlhaloso tsa QSFP+ MSA le IEEE 802.3ba 40GBASE-ER4. Ntle le moo, optic ea quad small form-factor pluggable (QSFP) ER4 e lekiloe lisebelisoa tsa moamoheli ho netefatsa hore e lumellana ka botlalo le lisebelisoa tsa Huawei, joalo ka li-switch tsa setsi sa data, li-router tsa khoebo, le likarete tsa sebopeho sa marang-rang a seva (NICs). Mojule oa 40G SFP oa motho oa boraro ke sebaka se loketseng sa transceiver ea Huawei QSFP-40G-ER4 QSFP+ 40G ka theko e tlase, e fanang ka tharollo e lumellanang le theko e tlase bakeng sa khokahano e phahameng ea 40G.
+ QSFP+ 40G ER4 optics e sebetsana le likhokahano tsa faeba ea optical ea 40 Gigabit Ethernet (40GbE), e loketseng lits'ebetso tse sebetsang hantle le tse hole marangrang a maeto a malelele, marangrang a khamphase, marangrang a metro, jj.

Tlhaloso e Akaretsang
OP-QSFP+-LER e etselitsoe ho sebetsa holim'a sistimi ea faeba ea mokhoa o le mong e sebelisa kanale ea 4X10 CWDM ka har'a sehlopha sa 1310 'me e hokela ho fihla ho 40km. Mojule o fetola kanale ea ho kenya e 4 ea data ea motlakase ea 10Gb/s ho ea ho matšoao a 4 a CWDM a optical, 'me o a eketsa ho ba kanale e le' ngoe bakeng sa phetiso ea optical ea 40Gb/s. Ka lehlakoreng le leng, ka lehlakoreng la moamoheli, mojule o tlosa li-multiplex ka mokhoa o hlakileng ho kenya ha 40Gb/s ho matšoao a 4 a CWDM a kanale, 'me o a fetolela ho data ea motlakase ea tlhahiso ea likanale tse 4.
Maqhubu a bohareng a dikanale tse 4 tsa CWDM ke 1271, 1291, 1311 le 1331 nm. E na le sehokelo sa duplex LC bakeng sa sebopeho sa optical le sehokelo sa di-pin tse 38 bakeng sa sebopeho sa motlakase. Faeba ya mokgwa o le mong (SMF) e sebediswa mojuleng ona. Sehlahiswa sena se fetola data ya ho kenya motlakase ya dikanale tse 4 tsa 10Gb/s ho ba matshwao a optical a CWDM (lesedi), ka sehlopha sa Distributed Feedback Laser (DFB) sa bolelele ba 4. Maqhubu a 4 a atoloswa ho ba data e le nngwe ya 40Gb/s, e phatlalatswang ho tswa mojuleng wa transmitter ka SMF. Mojule wa moamoheli o amohela ho kenya ha matshwao a optical a 40Gb/s, mme o a tlosa ho dikanale tse 4 tsa CWDM 10Gb/s. Lesedi le leng le le leng la bolelele ba motlakase le bokellwa ka diode ya photo discrete, ebe le ntshuwa e le data ya motlakase kamora ho hodiswa ke TIA.
Sehlahisoa sena se entsoe ka foromo, khokahano ea optical/electrical le sebopeho sa tlhahlobo ea dijithale ho latela QSFP+ Multi-Source Agreement (MSA) 'me se latela 40G QSFP+ LR4 ea IEEE 802.3ba.
