I-optical fiber attenuator yinxalenye ye-optical eyenzelwe ukunciphisa amandla esignali ye-optical. Isetyenziselwa ukunciphisa amandla e-optical optical, ngaloo ndlela ithintela ukuphazamiseka kwi-optical receiver okubangelwa ngamandla aphezulu okufaka. Njengenxalenye ye-optical engasebenziyo, i-fiber optic attenuator isetyenziswa kwiinkqubo zonxibelelwano lwe-optical ukulungisa ukusebenza kwamandla e-optical, ukulinganisa izixhobo ze-optical fiber, kunye nokunciphisa iimpawu ze-optical. Imveliso yenziwe kusetyenziswa i-attenuating fiber exutywe nee-ion zesinyithi, okuvumela ukulungiswa kwamandla e-optical ukuya kwinqanaba elifunekayo.

| IiMfuno zokuSebenza: |
| 1. Ukuphinda-phinda: Imijikelo yokufakwa/yokususwa eli-10; utshintsho kwilahleko yokufakwa ≤ 0.1 dB. |
| 2. Ukuqina koomatshini: Imijikelo yokufakwa/yokususwa engama-500; utshintsho kwilahleko yokufakwa ≤ 0.2 dB. |
| 3. Uvavanyo lokuwa: Ukuphakama kokuwa yi-1 m, amathontsi ama-5; utshintsho ekulahlekeni kokufakwa ≤ 0.1 dB. |
| 4. Ukungcangcazela: Ukuphindaphinda ukusuka kwi-10 Hz ukuya kwi-55 Hz, ubukhulu be-amplitude yi-0.75 mm, izinga lokutshiza yi-1 octave/min, imizuzu engama-30 nganye kwiindlela ezimbini ezithe nkqo; Utshintsho lokulahleka kokufakwa ≤ 0.2 dB. |
| 5. Ubushushu obuphezulu: Ubushushu yi-75°C, ubude bexesha yiiyure ezingama-96; utshintsho lokulahleka kokufakwa ≤ 0.2 dB. |
| 6. Ubushushu obuphantsi: Ubushushu -40°C, ubude bexesha ziiyure ezingama-96; utshintsho lokulahleka kokufakwa ≤ 0.2 dB. |
| 7. Ukujikeleza kobushushu: Uluhlu lobushushu: -25°C ukuya ku-+70°C; ubushushu obugqithisileyo bugcinwa imizuzu engama-30; izinga lokutshintsha kobushushu alidluli kwi-1°C/min; imijikelo emi-5; utshintsho kwilahleko yokufakelwa ≤ 0.2 dB. |
| 8. Ubushushu obufumileyo: Ubushushu yi-40°C, ukufuma yi-93%, ubude bexesha yi-48 iiyure; utshintsho kwilahleko yokufakwa ≤ 0.2 dB. |
| 9. I-Salt spray: Uxinzelelo lwe-Salt spray yi-5%; ubushushu yi-35°C, ubude bexesha yiiyure ezingama-48; utshintsho kwilahleko yokufakwa ≤ 0.2 dB. |
| 10. Ukungavuseleli Ilangatye: Ilangatye eliluhlaza okwesibhakabhaka (20±2) mm; isampuli nganye ivezwa kwilangatye kabini, imizuzwana engama-30 ngexesha ngalinye, kunye nesithuba semizuzu eli-10 phakathi kokuvezwa. Emva kokususwa kwilangatye, ixesha lokutsha elihlala lihleli kwisampuli nganye kufuneka libe ngaphantsi kwemizuzwana eli-10, kwaye umaleko osisiseko awuzukutsha. |
Qaphela: Iinkcukacha zinokutshintsha ngaphandle kwesaziso sangaphambili sokuphuculwa kwemveliso.
