KCO QSFP+ 40G ER4 40Gb/s QSFP+ SMF 1310 40km transceiver
Kedu ihe bụ QSFP + 40G ER4?
+ IheQSFP + 40G ER4 dakọtara 40G QSFP + transceiver modul nwere njikọ LC duplex, na-eru njikọ ruru 10km n'elu OS2 otu-mode fiber (SMF).
+ Nke a 40G fiber optical transceiver na-abịa na njikọ QSFP + njikọ bidirectional 4, na-enyere mkpokọta bandwidth 40 Gbps site na ọwa ọ bụla na-ebu data 10 Gbps.
+ A na-akwado ọrụ DOM/DDM (nleba anya nyocha dijitalụ) na transceiver fiber optic 40G iji nweta nleba anya na-arụ ọrụ ozugbo.
+ Anyị arụpụtara 40GBASE-ER4 QSFP modul kwekọrọ na nkọwa QSFP+ MSA na IEEE 802.3ba 40GBASE-ER4. E wezụga nke ahụ, a nwalere optic quad small form-factor pluggable (QSFP) ER4 optic na ngwaọrụ ndị ọbịa iji hụ na ndakọrịta zuru oke na akụrụngwa Huawei, dị ka mgbanaka etiti data, ndị na-anya ụgbọ ala, na kaadị netwọk netwọkụ (NICs). Ndị ọzọ 40G SFP modul bụ ezigbo ngbanwe na Huawei QSFP-40G-ER4 QSFP + 40G transceiver na ọnụ ahịa dị ọnụ ala, na-enye ngwọta dakọtara ọnụ maka ọnụ ahịa 40G na-arụ ọrụ dị elu.
+ QSFP + 40G ER4 optics na-enye 40 Gigabit Ethernet (40GbE) njikọ fiber optic, dị mma maka arụmọrụ dị elu na ngwa dị anya na netwọk ogologo oge, netwọk ụlọ akwụkwọ, netwọk metro, wdg.

Emebere OP-QSFP + -LER ka ọ rụọ ọrụ n'elu sistemu eriri otu ụdị site na iji ọwa 4X10 CWDM na band 1310 na njikọ ruo 40km. Modul ahụ na-agbanwe ọwa ntinye 4 nke data eletriki 10Gb / s na akara ngosi anya 4 CWDM, ma na-atụgharị ha n'otu ọwa maka nnyefe anya 40Gb / s. 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 ebili mmiri etiti nke ọwa 4 CWDM bụ 1271, 1291, 1311 na 1331 nm. Ọ nwere njikọ LC duplex maka interface anya yana njikọ 38-pin maka ngwa eletrik. A na-etinye eriri otu ụdị (SMF) na modul a. Ngwaahịa a na-atụgharị data ntinye eletriki 4-ọwa 10Gb/s n'ime akara ngosi anya CWDM (ọkụ), site na n'usoro 4-wavelength Distributed Feedback Laser (DFB). A na-agbanye ogologo 4 wavelength n'ime otu data 40Gb/s, na-agbasa site na modul nnyefe site na SMF. Modul nnata na-anabata ntinye akara ngosi anya 40Gb/s, wee mebie ya n'ime ọwa 4 CWDM 10Gb/s. A na-anakọta ọkụ n'ogologo ogologo ọ bụla site na diode foto pụrụ iche, wee wepụta ya dị ka data eletrik ka TIA gbasawanye ya.
Emebere ngwaahịa a na ụdị ụdị, njikọ anya / eletriki na interface nchọpụta dijitalụ dị ka QSFP + Multi-Source Agreement (MSA) si dị na 40G QSFP + LR4 nke IEEE 802.3ba.
