Multimode Patch Cord ULTIMODE PC-311D (2xSC-2xSC, duplex, OM3, 1.5m)



The patch cord ULTIMODE PC-311D is made of two parallel sections of OM3 multimode fiber optic cable with a length of 1.5 meters, each terminated with SC connector on both ends (in pairs). SC connectors are currently the most popular optical coupling elements due to simple matching (push-pull coupling with a snap), rectangular cross-section allowing dense packing of the connectors on the panel, and plastic construction (of course outside the ferrule).
ULTIMODE patch cords are characterized by low attenuation and back reflection (reflectance). They use highest quality ferrules. Each patchcord passes individual quality control (inspection of surfaces and measurement of transmission parameters - insertion and return loss).
The multimode fibers used in the cable are OM3 50/125, currently the most popular multimode fibers that can be used for transmission in the I or II transmission window (850/1310 nm). The attenuation (IL) does not exceed 3.5 dB/km in the first transmission window, and 1.5 dB/km in the second transmission window. OM3 standard provides higher data throughput over greater distances than its predecessors. The transmission speed of 10 Gbps is possible at distances up to 550 m, and higher speeds, such as 40 Gbps and 100 Gbps can be reached at 100 meters (OM1 and OM2 standards do not allow for such fast rates).
Key features:
  • connectors: 2 x SC to 2 x SC
  • two multimode fibers (OM3)
  • length: 1.5 m
  • low insertion loss
