40KM 40G QSFP+ Module transceiver anya
NkeHUAQ40Ebụ modul transceiver emebere maka ngwa nkwurịta okwu anya 40Km.Nhazi ahụ dabara na 40GBASE-ER4 nke ọkọlọtọ IEEE P802.3ba.Modul na-atụgharị 4 ntinye ọwa (ch) nke 10Gb / s eletriki data na 4 CWDM akara ngosi anya, na multiplexes ha n'ime otu ọwa maka 40Gb / s ngwa anya nnyefe.N'aka nke ọzọ, n'akụkụ nke nnata, modul optically de-multiplexes a 40Gb / s ntinye n'ime 4 CWDM ọwa akara, na-atụgharị ha na 4 ọwa mmepụta data eletriki.
Ogologo wavelength nke etiti nke ọwa 4 CWDM bụ 1271, 1291, 1311 na 1331 nm dị ka ndị otu CWDM wavelength grid akọwapụtara na ITU-T G694.2.Ọ nwere njikọ LC duplex maka interface anya yana njikọ 38-pin maka ngwa eletrik.Iji wedata mgbasawanye anya na sistemu ogologo oge, a ga-etinyerịrị eriri otu mode (SMF) na modul a.
Emebere ngwaahịa a n'ụdị ụdị, njikọ anya/ọkụ eletrik na interface nchọpụta dijitalụ dị ka Agreement Multi-Source Agreement (MSA) QSFP siri dị.Emebere ya ka ọ zute ọnọdụ ọrụ mpụga kacha sie ike gụnyere ọnọdụ okpomọkụ, iru mmiri na EMI.
Modul na-arụ ọrụ site na otu + 3.3V ike ọkọnọ na LVCMOS/LVTTL akara ngosi njikwa ụwa dị ka Module Present, Reset, Interrupt na Low Power Mode dị na modulu.Oghere Usoro nke waya abụọ dị maka izipu ma nata akara njikwa dị mgbagwoju anya yana ịnweta ozi nyocha dijitalụ.Enwere ike ilebara ọwa nke ọ bụla anya yana enwere ike mechie ọwa ndị na-ejighị ya maka mgbanwe nhazi kachasị.
Ngwaahịa a na-atụgharị data ntinye eletrịkị 4-ọwa 10Gb/s ka ọ bụrụ akara ngosi anya CWDM (ọkụ), site n'usoro 4-wavelength Distributed Feedback Laser (DFB).A na-ejikọta ọkụ ahụ site na akụkụ MUX dị ka data 40Gb / s, na-agbasa site na modul transmitter sitere na SMF.Modul nnata na-anabata ntinye akara ngosi anya 40Gb/s CWDM, wee mebie ya n'ime ọwa 4 nke ọ bụla 10Gb/s nwere ogologo wavele dị iche iche.A na-anakọta ọkụ ọ bụla nke ogologo ebili mmiri site na avalanche photodiode (APD), wee wepụta ya dị ka data eletrọnịkị ka agbachara nke mbụ site na TIA wee mechaa site na igwe nkwuputa.
NkeHUAQ40Eemebere ya n'ụdị ihe, njikọ anya/ọkụ eletrik na interface nchọpụta dijitalụ dị ka Agreement Multi-Source QSFP (MSA) siri dị.Emebere ya ka ọ zute ọnọdụ arụ ọrụ mpụga kacha sie ike gụnyere okpomọkụ, iru mmiri na ndabichi EMI.Modul ahụ na-enye ọrụ dị oke elu yana njikọta njirimara, nke a na-enweta site na interface serial waya abụọ.
