MTP/MPO Type-B Cable Categories

Based on its different functions, MTP type-B cable can be divided into two main categories: MTP Trunk cables and MTP-LC breakout cables. Depending on the nature of the socket MTP trunk cables are further divided into female-female, female-male, and male-male. When connecting two 40G SR4 QSFP+ transceivers in parallel optics, only female-female type B MTP cables should be used. For MTP-LC breakout cables, female MTP-LC breakout cables and male MTP-LC breakout cables are available.

Note: MTP connectors can be divided into female connector and male connector. Female connector does not have guide pins, while male connector has two guide pins. The connections between the connectors are precisely aligned with the pin, and the two MTP connectors connected to each other must be male and female.
