2. SFP optical modules, tse nyenyane tse amohelang li-plugable le li-light emitting modules (SFP), li sebelisoa haholo hona joale.
3. GigacBiDi letoto la li-single-fiber bidirectional optical modules li sebelisa theknoloji ea WDM ho lemoha phetiso ea fiber ea tlhahisoleseding ea litsela tse peli (phetiso ea ntlha-to-point. Haholo-holo, lisebelisoa tsa fiber ha li lekane, 'me fiber e le' ngoe e hlokahala ho fetisa matšoao a mabeli. ).GigacBiDi e kenyelletsa SFP single fiber bidirectional (BiDi), GBIC single fiber bidirectional (BiDi), SFP + single fiber bidirectional (BiDi), XFP single fiber bidirectional (BiDi), SFF single fiber bidirectional (BiDi) joalo-joalo.
4. Motlakase oa motlakase oa motlakase, mochine oa motlakase oa RJ45 o monyenyane oa motlakase, o tsejoang hape e le motlakase oa motlakase kapa motlakase oa motlakase.
5. SFF optical modules li arotsoe ka 2 × 5, 2 × 10, joalo-joalo ho ea ka lithapo tsa tsona.
6. GBIC optical module, Gigabit Ethernet interface converter (GBIC) module.
7. PON optical module, passive optical network PON (A-PON, G-PON, GE-PON) optical module.
8. 40Gbs e phahameng ea lebelo la optical module.
9. SDH phetiso module (OC3, OC12).
