MPO/MTP cables consist of multi-core joiners that give out more reliable and persistent presentation when utilized in condensed, low-loss wiring, therefore becoming a significant segment of 10G/40G data communication in big data centers. Thus standards of TIA interpret three kinds of cables of polarized MTP: Type A, B, and C. Different kinds of MTP polarity wires can have distinct implementations. This writing will primarily discuss type-B polarized MTP wires and their performances.

AN ANALYSIS OF TYPE-B MPO/MTP CABLE:
The essence of type-B MTP cable is to utilize a key-up joiner on both sides of the wire. The type-B cable is very flexible, primarily described as 40 Gigabit MTP wire. We can use this cable to plug straight between our 40 Gigabit QSFP+ optical fiber transceivers. You can observe in the diagram that this cable possesses a "flipped" polarity resulting in a relationship of Pin 1 to Pin 12. This cable is very effective as 40 Gigabit fiber optics use parallel fiber optics. The port will be similar to the given diagram rather than changing RX and TX into a duplex standard.
CLASSIFICATION OF TYPE-B MPO/MTP CABLE:
Founded on its multiple tasks, we can divide type-B MTP cable into two significant categories: MTP-LC breakout wires and Trunk cables. Determined by the types of socket, there is a further classification of trunk wires into male-male, female-male, and female-female. We should only use type-B MTP female-female cables While joining two 40 Gigabit SR4 QSFP+ optical transceivers in parallel fiber optics.
Male MTP-LC breakout cables and MTP-LC female cables are attainable for MTP-LC breakout wires.
NOTE: We can classify MTP joiners into male connectors and female connectors. Male connector possesses two guide pins, whereas female connector possesses no guide pins. We can observe a complete alignment with the hook of connections among the connectors. Moreover, these MTP connectors associated with each other should be female and male.
IMPLEMENTATIONS OF TYPE-B MPO/MTP CABLE:
Because of the specific creation of type-B MTP cable, we mostly require a female MTP connector to coordinate with the male MTP connector. The male guide pin is connected within the female bore to confirm absolute alignment. Two male or female connectors can cause light loss to the optical fiber splice. The examples given emphasize the implementation of female type-B MTP cables.
40G-40G STRAIGHT LINK: FEMALE TO FEMALE TYPE-B MPO/MTP POLARITY TRUNK CABLE:
Excluding the parallel 40 Gigabit optical fiber communication discussed earlier, female to female trunk wire can also be utilized for a straight switch to switch connection without patch panels. The diagram below manifests two cisco 40 Gigabit switches linked directly by a 12-optical fiber female MTP cable.
For attaching a QSFP+SR4 optical transceiver and a patch panel, we can utilize a type-B MTP trunk wire along with an MTP adapter.
40G-40X10 GIGABIT STRAIGHT LINK: FEMALE MTP TO TYPE-B MTP POLARITY BREAKOUT CABLES:
How can we connect a 40 Gigabit switch to a 10 Gigabit switch? A female type-B MTP-4XLC cable can sort out this problem without any difficulty. The figure below explains the four 10GBASE-SR optical transceivers connected with a single 40GBASE-SR4 optical transceiver directly by one female type-B MTP 4XLC cable.
40G-40G CONNECTIONS: MTP TYPE-B BREAKOUT CABLES AND MPO/MTP TYPE-B TRUNK CABLES:
We can jointly utilize Breakout cable and MTP type-B trunk cable to attain excellent performance optical fiber networking. In figure 5, we can see the interconnection of 10GBASE-LR SFP+ optical transceivers attached by breakout and MTP type-B trunk wire. It is a perfect explanation for joining two 40 Gigabit Cisco switches in a database by finishing the straight link of MTP optical fibers via optical fiber panels, clarifying cabling, and presenting high-speed optical fiber transmission.
CONCLUSION:
Type-B MPO/MTP cable finishes excessive speed data communication with its exclusive multi-core interface. According to the needs of your network apparatus, you can select the correct cable interface. GBIC presents base-12 and base-8 type-B MPO/MTP as 10/40 Gigabit interconnect and direct, upgrading fiber utilization, clarifying cabling, and facilitating the data centers to move to 40/100 Gigabit or more incredible speeds flexibly.
