Multi-Mode 50/125 μm OM2 Optical Fibre
Description :
- CONNECSYS 50/125µm OM2 multimode fibre is a graded-index multimode optical fibre with a 50µm core diameter and a 125μm cladding diameter. The optical fibre is comprehensively optimized for the performance at the 850nm and 1300nm operating wavelengths, which meet the requirement of EN187000 and TIA/EIA 568 of maximum attenuation of ≤ 3.5 dB at 850nm and ≤ 1.5 dB at 1300nm wavelengths. The optical fibre also complies with the ITU-T Recommendation G.651 and IEC 793-2 Type A1 Optical Fibre Specification. With the optical fibre low attenuation and high bandwidth, it overfills the transmission demand of IEEE 802.3z Gigabit Ethernet.
