2) ʻO TX Disable kahi mea hoʻokomo i hoʻohana ʻia e pani i ka hoʻopuka optical transmitter.Ua huki ʻia i loko o ka module me kahi pale pale 4.7 ¨C 10 K.ʻO kāna mau mokuʻāina:
Haʻahaʻa (0 a hiki i ka 0.8V): Mea hoʻouna ma

3) Mod-Def 0,1,2.ʻO kēia nā pine wehewehe module.Pono lākou e huki ʻia me kahi pale 4.7K a 10K ma ka papa hoʻokipa.ʻO ka voli huki huki he VccT a i ʻole VccR
Hoʻokumu ʻia ʻo Mod-Def 0 e ka module e hōʻike ai aia ka module
ʻO Mod-Def 1 ka laina uaki o ʻelua uea serial interface no serial ID
ʻO Mod-Def 2 ka laina ʻikepili o ʻelua uea serial interface no serial ID
4) ʻO LOS (Loss of Signal) he mea hōʻiliʻili wehe/wai puka, pono e huki ʻia me kahi pale 4.7K a 10K.Huki uila ma waena o 2.0V a me VccT, R+0.3V.Ke kiʻekiʻe, hōʻike kēia mea hoʻopuka i ka mana optical i loaʻa ma lalo o ka naʻau hoʻokipa maikaʻi loa (e like me ka wehewehe ʻana e ka maʻamau i hoʻohana ʻia).Hōʻike haʻahaʻa i ka hana maʻamau.Ma ka moku'āina haʻahaʻa, e huki ʻia ka huahana i <0.8V.
5) RD-/+: ʻO kēia nā mea hoʻopuka hoʻokipa ʻokoʻa.ʻO lākou nā AC i hui pū ʻia me 100 mau laina ʻokoʻa e hoʻopau ʻia me 100 (ʻokoʻa) ma ka mea hoʻohana SERDES.
