TheHUAQ40Eke mochine oa transceiver o etselitsoeng lisebelisoa tsa puisano tsa 40Km.Moqapi o lumellana le 40GBASE-ER4 ea IEEE P802.3ba e tloaelehileng.Mojule o fetola liteishene tsa li-input tsa 4 (ch) tsa data ea motlakase ea 10Gb / s ho matšoao a optical a 4 CWDM, 'me o li atisa ka mocha o le mong bakeng sa 40Gb / s optical transmission.Ka lehlakoreng le leng, ka lehlakoreng la moamoheli, mojule optically de-multiplexes ho kenya 40Gb / s ho li-signals tsa 4 CWDM, ebe o li fetolela ho data ea motlakase ea tlhahiso ea 4.
Maqhubu a bohareng a likanale tsa 4 CWDM ke 1271, 1291, 1311 le 1331 nm e le litho tsa marang-rang a marang-rang a CWDM a hlalositsoeng ho ITU-T G694.2.E na le sehokelo sa duplex LC bakeng sa sebopeho sa optical le sehokelo sa 38-pin bakeng sa sebopeho sa motlakase.Ho fokotsa ho hasana ha optical tsamaisong ea nako e telele, fiber ea mofuta o le mong (SMF) e tlameha ho sebelisoa mojuleng ona.
Sehlahisoa se entsoe ka sebopeho sa sebopeho, khokahano ea optical / motlakase le sebopeho sa tlhahlobo ea dijithale ho latela Tumellano ea QSFP Multi-Source (MSA).E etselitsoe ho kopana le maemo a thata a ts'ebetso a kantle ho kenyelletsa mocheso, mongobo le tšitiso ea EMI.
Mojule o sebetsa ho tloha ho matla a le mong + 3.3V le lipontšo tsa taolo ea lefats'e ea LVCMOS / LVTTL tse kang Module Present, Reset, Interrupt le Low Power Mode li fumaneha ka li-module.Khokahano ea serial ea 2-wire e fumaneha ho romella le ho amohela matšoao a thata a taolo le ho fumana tlhaiso-leseling ea tlhahlobo ea dijithale.Liteishene ka bomong li ka rarolloa 'me likanale tse sa sebelisoeng li ka koaloa bakeng sa maemo a phahameng a moralo.
Sehlahisoa sena se fetola lintlha tsa motlakase oa 4-channel 10Gb / s ho li-CWDM optical signals (leseli), ka mokhoa o tsamaisoang oa 4-wavelength Distributed Feedback Laser (DFB).Leseli le kopantsoe ke likarolo tsa MUX e le data ea 40Gb / s, e phatlalatsang ho tsoa ho module ea transmitter ho tloha ho SMF.Mojule oa ho amohela o amohela 40Gb / s CWDM optical signal input, le de-multiplexes ho likanale tsa 4 tsa 10Gb / s tse nang le maqhubu a fapaneng a maqhubu.Leseli le leng le le leng la bophahamo ba maqhubu le bokelloa ke avalanche photodiode (APD), ebe e hlahisoa e le data ea motlakase ka mor'a hore e holisoe pele ke TIA ebe ka poso amplifier.
TheHUAQ40Ee entsoe ka sebopeho sa sebopeho, khokahanyo ea optical / motlakase le sebopeho sa tlhahlobo ea dijithale ho latela Tumellano ea QSFP Multi-Source Agreement (MSA).E etselitsoe ho kopana le maemo a thata ka ho fetisisa a ts'ebetso ea kantle ho kenyelletsa mocheso, mongobo le tšitiso ea EMI.Mojule o fana ka ts'ebetso e phahameng haholo le kopanyo ea likarolo, e fumanehang ka sebopeho sa serial sa terata tse peli.
