I-Mylinking™ Optical Transceiver Module SFP LC-MM 850nm 550m

I-ML-SFP-MX 1.25Gbps SFP 850nm 550m LC Multi-Mode

Incazelo emfushane:

I-Mylinking™ RoHS Compliant 1.25Gbps 850nm Optical Transceiver 550m Reach ukusebenza okuphezulu, amamojula angabizi kakhulu asekela izinga ledatha le-1.25Gbps kanye nebanga lokudlulisela elingu-550m nge-MMF. I-transceiver iqukethe izigaba ezintathu: i-laser transmitter ye-VCSEL, i-PIN photodiode ehlanganiswe ne-trans-impedance preamplifier (TIA) kanye neyunithi yokulawula ye-MCU. Wonke amamojula anelisa izidingo zokuphepha ze-laser zekilasi I. Ama-transceivers ahambisana ne-SFP Multi-Source Agreement (MSA) kanye ne-SFF-8472. Ukuze uthole ulwazi olwengeziwe, sicela ubheke ku-SFP MSA.
