Mofuta:
Bend Insensitive Mode o le Mong oa Optical Fiber (G.657.A2)
Tloaelo:
Fiber e lumellana kapa e feta litlhaloso tsa tekheniki ho ITU-T G.657.A1/A2/B2.
Sebopeho:
Bonyane ba ho kobeha radius 7.5mm, thepa e phahameng e thibelang ho kobeha;
E lumellana ka botlalo le G.652 fiber ea mofuta o le mong. Phetiso ea sehlopha se felletseng (1260 ~ 1626nm);
PMD e tlase bakeng sa phetisetso ea lebelo le holimo le sebaka se selelele. Phokotso e tlase haholo ea micro-bending, e sebetsang bakeng sa mefuta eohle ea lithapo tsa optical ho kenyeletsoa le liribone;
Paramethara e phahameng ea anti-fatigue e netefatsa bophelo ba ts'ebeletso tlasa radius e nyane ea ho kobeha.
Kopo:
Mehaho eohle ea li-cable, 1260 ~ 1626nm phetiso e felletseng ea li-band, FTTH high speed optical routing, thapo ea optical sebakeng se senyenyane se kobehang, thapo e nyane ea optical fiber le sesebelisoa.

Fektheri ea Optical Cable
Ka 2004, GL FIBER e thehile feme ho hlahisa lihlahisoa tsa optical cable, haholo-holo tse hlahisang li-drop cable, outdoor optical cable, joalo-joalo.
Hona joale GL Fiber e na le lisebelisoa tse 18 tsa lisebelisoa tsa mebala, lihlopha tse 10 tsa lisebelisoa tsa ho roala ka polasetiki, lihlopha tse 15 tsa lisebelisoa tse sothang tsa SZ, lihlopha tse 16 tsa lisebelisoa tsa sheathing, lisebelisoa tse 8 tsa lisebelisoa tsa tlhahiso ea li-cable tsa FTTH, lisebelisoa tse 20 tsa OPGW optical cable, le 1 lisebelisoa tse tšoanang Le lisebelisoa tse ling tse ngata tse thusang tlhahiso. Hajoale, matla a tlhahiso ea selemo le selemo a likhoele tsa optical a fihla ho limilione tse 12 tsa mantlha (karolelano ea matla a tlhahiso ea letsatsi le letsatsi a lik'hilomithara tse 45,000 le mefuta ea likhoele e ka fihla ho 1,500 km). Lifeme tsa rona li ka hlahisa mefuta e fapaneng ea likhoele tsa optical tsa kahare le kantle (tse kang ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, micro-cable e butsoeloang ke moea, joalo-joalo). matla a letsatsi le letsatsi a tlhahiso ea lithapo tse tloaelehileng a ka fihla ho 1500KM / letsatsi, matla a letsatsi le letsatsi a tlhahiso ea cable a ka fihlang max. 1200km / letsatsi, mme matla a tlhahiso ea letsatsi le letsatsi a OPGW a ka fihla ho 200KM / letsatsi.
