Fiber yemhando imwe chete: G652D vs G657A2

1/ Chii chinonzi single-mode fiber?

+ Fiber yemhando imwe chete ifiber ye optical yakagadzirirwa kutakura nzira imwe chete yechiedza - iyo transverse mode.

+ Fiber ye optical yakajairika ine dhayamita yepakati iri pakati pe8 kusvika 10.5 μm (yakajairika i9μm) uye dhayamita ye cladding ye125 μm.

+ OS1 neOS2 ifiber ye optical ye 9/125 μm single-mode. Dzese dzinoshandiswa ne wavelengths ye 1310 nm uye 1550 nm.

+ Fiber yemhando imwe chete yakagadzirirwa kutumira zvinhu zvinofamba nekumhanya kukuru, zvichibatsira pakufamba kwemakiromita maviri kusvika makiromita zana nemakumi matanhatu.

+ Maumbirwo efaibha yakajairika yemodhi imwe chete:

Chinhu chikuru:dhayamita ye 8–9 μm

Kufukidza:dhayamita ye125 μm

Buffer:dhayamita ye 250 μm

Bhechi:dhayamita ye600 kana 900 μm

2/ G652D Fiber yemhando imwe chete:

+ G652D Single-mode Fiber ndiyo inonyanya kushandiswa ye standard single-mode optical fiber (SMF), yakagadziriswa neITU-T yekukurukurirana nekukurumidza uye kure.

+ Ine tekinoroji ye "low water peak", ichideredza kurasikirwa kwechiratidzo muhuwandu hwe1383 nm wavelength.

+ Inozivikanwa nebandwidth yakakwira, kuderera kwesimba remagetsi, uye kuenderana nedata kumashure, yakanakira network dzekutaurirana, Metropolitan Area Networks (MAN), uye Fiber to the Home (FTTH) applications.

3/ G657A2 Fiber yemhando imwe chete:

+ G.657A2 Single-mode Fiber ifiber isingabatike zvakanyanya, inoenderana nezvinodiwa neITU-T, yakagadzirwa kuti ishande isina kurasikirwa kukuru kwechiratidzo pa tight bending radii (yakaderera se7.5mm).

+ Inoenderana zvizere neG.652D fiber, zvichiita kuti ive yakakodzera tambo dzeFTTH dzinodonha dzine density yakakura, waya dzemukati, uye nzvimbo diki, dzakareba.
