Plan 40G, 100G, 400G and 800G MPO/MTP data center links. Check interface compatibility, Type A/B/C polarity, pinned or unpinned gender, trunk length, cassette structure, breakout mapping and estimated insertion loss before sending an RFQ.
Select the network application first. Module options will be filtered by selected speed.
Risk messages are sorted by priority: red warnings first, then yellow checks, then green confirmations.
Copy this configuration into your inquiry message. It summarizes the selected network speed, module family, MPO/MTP interface, polarity, gender, end face, trunk length, estimated insertion loss and recommended ZION product scope.
Product suggestions update according to the selected link type, interface and breakout requirement.
Common questions about MPO/MTP polarity, pinned and unpinned connectors, MPO-12 vs MPO-16, 400G/800G cabling, breakout links, cassette design and insertion loss planning.
This planner helps engineers and procurement teams prepare an MPO/MTP cabling RFQ before ordering. It checks network speed, module family, connector interface, polarity, gender, trunk length, cassette quantity, MPO mated point quantity, breakout requirement and estimated insertion loss.
MPO is the generic multi-fiber push-on connector type, while MTP is a premium MPO-style connector brand. In many data center cabling discussions, MPO and MTP are used together because they refer to the same multi-fiber connection category. For ordering, always confirm connector type, fiber count, polarity, gender and end face.
The correct choice depends on the optical module family and link architecture. 40G SR4 and 100G SR4 often use MPO-8 or MPO-12. 400G DR4 commonly uses MPO-12 single-mode cabling. 400G SR8 and many 800G SR8/DR8 applications may require MPO-16 or a vendor-specific interface. MPO-24 is more often used for high-density trunking rather than direct transceiver connection.
MPO polarity controls how transmit and receive fibers are mapped from one end of the link to the other. If Type A, Type B or Type C polarity is selected incorrectly, the optical link may not come up even when the cable quality is good. For parallel optics such as SR4, SR8, DR4 and PSM4, polarity confirmation is especially important before production.
Pinned MPO connectors are also called male connectors, while unpinned MPO connectors are also called female connectors. Optical transceivers usually have guide pins inside the module interface, so the patch cord connected to a transceiver is usually female / unpinned. Mating two male connectors can damage pins, while mating two female connectors can cause alignment failure.
Low-loss MPO/MTP assemblies are recommended when the link has multiple patch panels, cassettes, adapter points or high-speed 400G/800G requirements. More mated pairs increase insertion loss, so low-loss connectors help preserve link margin in complex data center routes.
It depends on the module type. Some 400G and 800G links use parallel optics and may require direct MPO/MTP paths rather than MPO-to-LC cassette conversion. Cassettes are useful for structured cabling and LC breakout designs, but the final layout must match the optical module interface, polarity method and loss budget.
A complete MPO/MTP RFQ should include:
No. This planner is designed for pre-sales engineering and RFQ preparation. Final acceptance should always be based on the optical module datasheet, project specification, polarity test report, insertion loss test result and actual installation requirements.
