With 4-core, you have two instant spares. Future Expansion: You can use the extra pair for Link Aggregation (LACP) later to double your bandwidth without running new cable. Negligible Cost Difference: The cost of the glass fiber itself is low. When selecting fiber, the first step is to determine single mode or multimode, and. The number of optical cores in an optical fiber is the total number of equipment interfaces multiplied by 2, plus 10% to 20% of the spare quantity, and if the communication mode of the equipment has serial communication and equipment multiplexing, you can reduce the number of cores. The number of. Option A - Splice cores 1-20 in succession with no gaps to connect the switches. ie: joint 1 cut and splice cores 1-4. One key factor is the number of cores, which impacts how much data you can transmit.
