Thapo ea SM G657 MPO APC ho ea ho LC Fan-out 24F Patch / Mono mode 24fibers MTP APC ho ea ho LC Harness Cable Type B

- Bakeng sa thapo ya 24F MPO ho ya ho LC harness / MTP ho ya ho LC harness, ho etsa 'mapa ho itshetlehile ka hore na o sebedisa polarity e tlwaelehileng ya Mofuta wa A, Mofuta wa B, kapa Mofuta wa C.

- Sebopeho se tloaelehileng haholo ke Mofuta oa B (Rollover), o hokahanyang Pin 1 sehokelong sa MPO le Channel 12 ka lehlakoreng la LC, le Pin 2 ho Channel 11.

- 'Mapa o nepahetseng oa polarity o itšetlehile ka maemo a hlophisitsoeng a likhoele (TIA-568) ao u a latelang:

+ Mofuta oa A (Otlolohile): Fiber 1 e hokela ho Fiber 1, Fiber 2 ho Fiber 2, jj. Ho netefatsa hore Transmit-to-Receive (Tx-to-Rx) e tsamaellana hantle, pheletso e 'ngoe ea khokahano e hloka thapo e tloaelehileng ea crossover patch (A-to-B).

+ Mofuta oa B (E Khutlisitsoeng/E Phetlang): Fiber 1 e hokela ho Fiber 24, Fiber 2 ho Fiber 23, jj. Mokhoa ona o tumme haholo bakeng sa ho lokisa lisebelisoa ka kotloloho (joalo ka li-transceiver tsa 40G/100G) kaha e fetola Tx le Rx ka bo eona ntle le mathata.

+ Mofuta oa C (E Fetotsoe ka Bobeli): Lipara tsa faeba tse haufi lia fapanyetsanoa (mohlala, 1↔2, 3↔4, 5↔6). Sena se boloka ho lumellana ho tloaelehileng ha Tx/Rx ntle le ho hloka likhoele tsa patch tse crossover, empa se hloka likhoele tsa trunk tse hlophisitsoeng ka hloko.
