Method A/C: Cat. Nos. 0 321 42/43/44/45 – 0 321 48/49
Identical cassettes. Cords A to B at one end and cords A to A at the other end – trunk type A

Method A/C: Cat. Nos. 0 321 42/43/44/45 – 0 321 48/49
Identical cassettes. Cords A to B at both ends – trunk type C.

Method B, single mode/multimode made-to-order product (9 001 26/36)
Different cassettes (B1 and B2). Cords A to B at both ends – trunk type B.

For singlemode cassettes with polarity B (key-up/key-up feedthrough), the male MTP connector for the cassette is up-angled in accordance with IEC 61754-1-12 and therefore only compatible with standard polarity B female MTP (or MPO) trunks (down-angled). Polarity B trunks available made-to-order
