MPO/MTP Cabling Guide


40G MPO/MTP Cabling


12-fiber MPO/MTP connectors can accommodate 40G, typically used in 40G data centers. A typical implementation of an MPO/MTP plug-and-play system divides a 12-fiber trunk fiber cable into six channels, running up to 10 Gigabit Ethernet (depending on the cable length). 40G systems use a 12-fiber trunk to create Tx/Rx links, dedicating 4 fibers for each 10G uplink transmission and 4 fibers for each 10G downlink reception.


40G-40G Connection


Using a 12-fiber MPO trunk cable to connect two 40G optical modules achieves a 40G to 40G connection between two switches. This connection method can also be applied to 100G to 100G connections.


40G Trunk Fiber Cabling


24-fiber MTP to MTP interconnect conversion harness cables are designed to provide a more flexible multi-fiber cabling system based on MTP products. Unlike MTP harness cables, MTP conversion cables have MTP connectors at both ends, offering more possibilities for existing 24-fiber cabling systems. 40/100G MTP conversion cables eliminate fiber waste in current 40G transmissions and upcoming 100G transmissions. Using MTP conversion cables is a more cost-effective and lower-loss option compared to purchasing and installing separate conversion boxes.


100G MPO/MTP Cabling


Using 4 fiber pairs, QSFP28 100G transceivers have a 12-fiber MPO port (with 4 unused fibers). Using SR4 transmission over multimode fiber is the most cost-effective for short distances (up to 100m). Using 8-fiber PSM4 transmission provides longer distances than single-mode transmission. By transmitting over 4 fiber pairs, an MPO-LC 8-fiber harness cable can connect multimode and single-mode transceivers at a 1:4 ratio. One 100G QSFP28 active optical cable can connect to four SFP28 25G optical modules.
