I-Optical Module

25Gbps 10km Duplex LC SFP28 Transceiver

Incazelo

Ama-transceiver e-SFP28 enzelwe ukusetshenziswa kuzixhumanisi ze-25-Gigabit Ethernet ezifika ku-10km nge-Single Mode Fiber.

Ama-transceivers ahambisana ne-INF-8431 kanye ne-SFF-8472. Ukuze uthole ulwazi olwengeziwe, sicela ubhekisele ku-INF-8431 kanye ne-SFF-8472.

Amanothi:

1. Ixhumeke ngqo kumaphini wokufaka wedatha we-TX. Ukuhlangana kwe-AC kusuka kumaphini ku-laser driver IC.

2. I-LOS iwukuphuma komqoqi ovulekile. Kufanele idonswe nge-4.7kΩ – 10kΩ ebhodini lomsingathi. Ukusebenza okujwayelekile kungu-logic 0; ukulahlekelwa isignali kuwumqondo 1.

I-Digital Diagnostic Memory Map (Ihambisana ne-SFF-8472)

Ama-transceivers ahlinzeka ngokuqukethwe kwememori ye-serial ID kanye nolwazi lokuxilonga mayelana nezimo zokusebenza zamanje nge-2-wire serial interface (SCL, SDA).

Ulwazi lokuxilonga olunokulinganiswa kwangaphakathi noma ukulinganisa kwangaphandle konke kuyasetshenziswa, okuhlanganisa ukuqapha amandla atholiwe, ukuqapha amandla adluliswayo, ukuqapha kwamanje okuchemile, ukuqapha ukuhlinzekwa kwamandla kagesi kanye nokuqapha izinga lokushisa.

Inkambu yedatha ethile yedatha yemephu yokuxilonga yedijithali ichaza njengokulandelayo (Ukuze uthole ulwazi olwengeziwe, sicela ubhekisele ku-SFF-8472).
