相比OM1和OM2光纤,OM3具备更高的传输速率及带宽,所以也称为优化型多模光纤或万兆多模光纤。 4、OM4光纤是OM3多模光纤的升级版,性能更加优越,如,OM4光纤的有效带宽是OM3光纤的一倍多,可兼容OM3光纤,外护套为水蓝色。在10Gbps以上的以太网中,OM4光纤比OM3光纤传输距离更远,可达400米。 5、OM5光纤是一种最新推...
from 850 nm to 940 nm that OM5 delivers a meaningful performance improvement compared to OM4. In these cases, the cost increase is worthwhile. The vast majority of multimode transceivers operate only at 850 nm, however. In these cases, there is no reach benefit for OM5 ...
Good: very good cost performance and video features. AF no longer pulsates like the old Panasonic cameras. Good IBIS for a FF. Poor: Low burst rates. Slow maximum shutter speed (might need to use filters to shoot primes wide open in good light.) Mechanical is 1/8000. Same as all othe...
