1.25Gb/s 1310nm Hal-habka Gudbinta SFP

1.25Gb/s 1310nm Hal-hab SFP Gudubiyaha Sawirka leh

Sharaxaad Gaaban:

Transceivers waxay ku habboon yihiin Foomka Yar ee Factor Pluggable Pluggable (SFP) Agreement Multi-Sourcing (MSA). Transceiver-ku wuxuu ka kooban yahay afar qaybood: darawalka LD, amplifier xaddidan, laser FP iyo sawir-qaade PIN. Xogta moduleka waxay isku xirtaa ilaa 20km gudaha 9/125um fiber hal qaab ah.

Wax soo saarka indhaha waxa dami kara TTL caqli gal heer sare ah oo Tx Disable ah. Fault Tx waxaa la bixiyaa si loo muujiyo hoos u dhaca laysarka. Luminta signalka (LOS) soo saarista waxa la bixiyaa si ay u muujiso luminta calaamada wax gelinta ee qaataha ama heerka xidhiidhka lamaanaha.

Xusuusin:
1.Circuit ground waa gudaha ka go'doon dhulka chassis.
2.Laser soo saarista naafo TDIS>2.0V ama furan, karti u TDIS <0.8V.
3.Waa in lagu soo jiidaa 4.7k - 10kohms ee guddiga martida loo yahay danab u dhexeeya 2.0V iyo 3.6V.MOD_DEF (0) jiidaya line hoose si ay u muujiyaan module ku xiran yahay.
4.Tani waa ikhtiyaari ikhtiyaari ah oo loo isticmaalo in lagu xakameeyo xajinta xajmiyada qaataha si ay ula jaanqaadaan heerarka xogta badan (waxay u badan tahay Fiber Channel 1x iyo 2x Rates) .Haddii la fuliyo, gelinta ayaa gudaha hoos loogu dhigi doonaa> 30kΩ resistor. Qodobbada wax lagu soo gelinayo waa:
- Hooseeyo (0 - 0.8V): Bandwidhthka oo la dhimay
- (> 0.8, <2.0V): Aan la qeexin
- Sare (2.0 - 3.465V): bandwidth buuxa
- Furan: Bandwidth la dhimay
5.LOS waa wax soo saarka ururiyaha furan waa in lagu soo jiido 4.7k - 10kohms ee guddiga martida loo yahay danab u dhexeeya 2.0V iyo 3.6V. Logic 0 wuxuu muujinayaa hawlgal caadi ah; macquulka 1 wuxuu muujinayaa luminta calaamadda.
