ML-SFP-MX 1.25Gbps SFP 850nm 550m LC Mekhoa e mengata

Tlhaloso e Khutšoanyane:

Mylinking™ RoHS Compliant 1.25Gbps 850nm Optical Transceiver 550m Reach ke di-module tse sebetsang hantle haholo, tse theko e tlase tse tshehetsang sekgahla sa data sa 1.25Gbps le sebaka sa phetiso sa 550m le MMF. Transceiver e na le dikarolo tse tharo: transmitter ya laser ya VCSEL, photodiode ya PIN e kopantsweng le trans-impedance preamplifier (TIA) le yuniti ya taolo ya MCU. Di-module tsohle di fihlela ditlhoko tsa polokeho ya laser ya sehlopha sa I. Di-transceiver di tsamaisana le SFP Multi-Source Agreement (MSA) le SFF-8472. Bakeng sa tlhahisoleseding e batsi, ka kopo sheba SFP MSA.
