Mtengo wotsika wa China sfp-1.25g base-sr sfp + stercecer fider Module, 1310nm, 20km

Pitani ndi mgwirizano ", zimagwirizana ndi gawo la msika, kulowa mu mpikisano wamsika ndi mtundu wake wabwino nthawi yomweyo monga kampani yokwanira kuti akule bwino. Kuchita nawo kampani, ndi chisangalalo cha makasitomala pamtengo wotsika ku China sfp-210g fir-SR SR-SR SRE-SR SIRD-SR SRA-SR SRE-SR SR-SR SR-SR SRE-SR SR-SRR SURK Tikudziwa kuti zomwe tachita bwino kwambiri pakupanga zida zidzapambana kasitomala, ndikulakalaka kugwira ntchito ndikupanga tsogolo labwino ndi inu!
Pitani ndi mgwirizano ", zimagwirizana ndi gawo la msika, kulowa mu mpikisano wamsika ndi mtundu wake wabwino nthawi yomweyo monga kampani yokwanira kuti akule bwino. Kuthamangira pa kampani, kudzakhala kosangalatsa kwa makasitomala1.25g sfp module, China SFP Module, Kukhutitsidwa ndi mbiri yabwino kwa kasitomala aliyense ndiye zofunika patsogolo. Timayang'ana mwatsatanetsatane makonzedwe okonza makasitomala mpaka atalandira katundu wotetezeka komanso wowoneka bwino ndi ntchito zabwino zamisonkhano komanso mtengo wachuma. Kutengera izi, katundu wathu wagulitsidwa bwino m'maiko ku Africa, kummawa ndi Southeast Asia.

Chithunzi chogwirira ntchito

Malingaliro okwanira

Zindikirani: Kupsinjika kwambiri kwa mavoti okwera kwambiri kumatha kuwonongeka kwamuyaya kwa wotchinga.

Makhalidwe Ogwirira Ntchito

Magetsi (pamwamba (c) = 0 mpaka 70 ℃, pamwamba (i) = -40 mpaka 85 ℃, ℃cc = 3.47 v)

Zolemba:

1. Td +/ ndi mkati mwa anthu omwe amaphatikizidwa ndi 100-2ω osiyana mkati mwa gawo.

2. Kulakwitsa kwa TX ndi RX Los ndi zotumphukira zotsekemera, zomwe ziyenera kukokedwa ndi 4.7k mpaka 10k y 10k river pa bolodi. Konzani magetsi pakati pa 2,0V ndi VCC + 0.3v.

3. Rd +/- Zotuluka mkati mwake ma als aphatikizidwa, ndikuyenera kuthetsedwa ndi 100ω (kusiyanitsa) pa serses.

Makhalidwe owoneka bwino (c) = 0 mpaka 70 ℃, pamwamba (i) = -40 mpaka 85 ℃, ℃cc = 3.47 v)

Zolemba:

1. Kuyeza ku 1.255gb / s ndi prbs 2 2^{23 - 1}Njira yoyeserera ya NRZ.

2. Odalirika, oyeza ndi prob2^{23 - 1}CHINSINSI CHA @ 1.25gbps

3. Kuyezedwa pa 1.25gb / s ndi prbs 2^{23 - 1}NRZ Kuyesa Kolinga kwa Ber <1 × 10^-12

Matanthauzidwe a PIN ndi ntchito

Zolemba:

1. Mkuluyo, kutulutsa kumeneku kumawonetsa cholakwika cha mtundu wina. Kutsitsidwa kumawonetsa ntchito wamba. Ndipo iyenera kukokedwa ndi 4.7 - 10k

2. Tx Lement ndi cholowa chomwe chimagwiritsidwa ntchito kutseka zotulutsa zotulutsa zotulutsa. Imakokedwa mkati mwa gawo ndi 4.7 - 10k ness. Mayiko ake ndi awa:

Otsika (0 - 0.8v): Kutumiza pa (> 0,8, <2.0v): Osakhazikika

Okwera (2.0v ~ ~ ~ vcc + 0.3v): Transmitter yolumala: "kutumiza kwalumala

3. Mad-def 0,1,2. Awa ndi ma pini otanthauzira a Module. Ayenera kukokedwa ndi 4.7k - 10k gwiritsani ntchito bolodi. Mphamvu yamagetsi ikhale pakati pa 2,0V ~ vcc + 0.3v.

Mod-def 0 yakhazikika ndi gawo losonyeza kuti gawo limapezeka

Mod-def 1 ndi mzere wotchi ya waya wa waya wa seri ya seri

Mod-def 2 ndi mzere wa ma waya awiri a waya wa seri

4. Pakukwera, izi zimawonetsa kutayika kwa chizindikiro (Losa). Kutsitsidwa kumawonetsa ntchito wamba.

5. Rd +/-: awa ndi zotulutsa zina. Amakhala mizere yosiyanasiyana yosiyanasiyana yomwe iyenera kuyimitsidwa ndi 100ω (yosiyanitsa) pa serses. Kuphatikizika kwa Ac kumachitika mkati mwa gawo ndipo sikufunikira pa bolodi.

6. TD +/: Awa ndi kulowetsa kosiyana. Amakhala ndi mizere yosiyanasiyana yosiyanasiyana yosiyanasiyana ya 100ω yosiyanasiyana mkati mwa gawo. Kuphatikizika kwa Ac kumachitika mkati mwa gawo ndipo sikufunikira pa bolodi.

Kuzindikira kwa Digital

Makina ogulitsa atha kugwiritsidwa ntchito munthawi zonse zomwe zimafunikira mkati kapena pozindikira matenda a digiriya.

Zolemba:

1.Pakugwiritsa ntchito temple. = 0 ~ 70 ºC, mtunduwo udzakhala mphindi =-5, max = + 75

2. Kulondola kwa TX Missias pakalipano ndi 10% ya omwe ali pakompyuta ya Laser kupita ku laser

3. Thumba la mkati / kunja logwirizana.
