KCO QSFP+ 40G ER4 40Gb/s QSFP+ SMF 1310 40km Transceiver
O LE Ā LE QSFP+ 40G ER4?
+ LeE fetaui lelei le QSFP+ 40G ER4 ma e fa'apipi'iina le 40G QSFP+ transceiver module i LC duplex connectors, e o'o atu i le 10km le mamao e ala i le OS2 single-mode fiber (SMF).
+ O lenei masini e fa'asalalau ai fe'au fa'a-fiber optical 40G e sau ma se feso'ota'iga QSFP+ e 4 auala i itu e lua, e mafai ai ona maua le aofa'i o le bandwidth e 40 Gbps i auala ta'itasi e tauaveina le fua faatatau o fa'amaumauga e 10 Gbps.
+ O le galuega faatino a le DOM/DDM (digital diagnostics monitoring) e lagolagoina i le 40G fiber optic transceiver e ausia ai le mata'ituina o fa'agaioiga i le taimi moni.
+ Na matou gaosia le module 40GBASE-ER4 QSFP+ e ogatasi ma faʻamatalaga o le QSFP+ MSA ma le IEEE 802.3ba 40GBASE-ER4. E le gata i lea, o le quad small form-factor pluggable (QSFP) ER4 optic ua uma ona faʻataʻitaʻiina i masini talimalo e faʻamautinoa ai le fetaui lelei ma masini a Huawei, e pei o data center switches, enterprise routers, ma server network interface cards (NICs). O le module lona tolu o le 40G SFP o se sui lelei tele i le Huawei QSFP-40G-ER4 QSFP+ 40G transceiver i se tau taugofie, ma maua ai se fofo taugofie mo le fesoʻotaʻiga 40G maualuga le faʻatinoga.
+ O masini fa'apitoa QSFP+ 40G ER4 e fetaui ma feso'ota'iga alava opitika 40 Gigabit Ethernet (40GbE), e fetaui lelei mo fa'aoga maualuga ma mamao i feso'ota'iga mamao, feso'ota'iga i le lotoa a'oga, feso'ota'iga metro, ma isi.

Fa'amatalaga Lautele
Ua mamanuina le OP-QSFP+-LER e fa'agaoioia i luga o le faiga o le fiber mode e tasi e fa'aaoga ai le 4X10 CWDM channel i le 1310 band ma feso'ota'i e o'o atu i le 40km. E liua e le module le 4 inputs channel o le 10Gb/s electrical data i le 4 CWDM optical signals, ma fa'atele i latou i se tasi channel mo le 40Gb/s optical transmission. I le isi itu, i le itu e talia ai, e fa'ate'a ese e le module le 40Gb/s input i totonu o le 4 CWDM channels signals, ma fa'aliliu i latou i le 4 channel output electrical data.
O galu tutotonu o ala e 4 CWDM o le 1271, 1291, 1311 ma le 1331 nm. O lo'o i ai se feso'ota'iga LC duplex mo le va'aiga opitika ma se feso'ota'iga 38-pin mo le va'aiga eletise. O le alava fa'a-tasi (SMF) o lo'o fa'aogaina i lenei module. O lenei oloa e liua ai fa'amatalaga eletise e 4-ala 10Gb/s i fa'ailo opitika CWDM (malamalama), e ala i se fa'asologa o le 4-wavelength Distributed Feedback Laser (DFB). O galu e 4 e fa'atele i totonu o se fa'amatalaga e tasi e 40Gb/s, e fa'asalalau atu mai le module transmitter e ala i le SMF. E talia e le module receiver le ulufale mai o fa'ailo opitika 40Gb/s, ma fa'ate'aina i totonu o ala e 4 CWDM 10Gb/s. O malamalama galu ta'itasi e aoina e se photo diode fa'apitoa, ona fa'asalalau lea o ni fa'amatalaga eletise pe a uma ona fa'amalosia e se TIA.
O le oloa ua mamanuina ma le form factor, feso'ota'iga opitika/eletise ma le digital diagnostic interface e tusa ai ma le QSFP+ Multi-Source Agreement (MSA) ma e tausisia le 40G QSFP+ LR4 o le IEEE 802.3ba.
