1. Single MPO-12 ribbon connector (-SR4, -eSR4, -IR4 PMS, -LR4 PSM), duplex LC/PC connector (-IR4, -LR4, -ER4).
2. Minimum cabling distance is 0.5 meters for -SR4, eSR4 and LX4, and 2 meters for IR4, -LR4 and ER4 according to the IEEE 802.3 standard.
3. Links longer than 30 km for the same link power budget are considered engineered links as per IEEE 802.3 Table 87–6. Attenuation for such links needs to be less than the worst case specified for single mode fiber to guarantee operation.
