8 Fiber MPO OM4 Patch Cable for 40G and 100G Networks
The 8 fiber MPO OM4 patch cable provides a high-density cabling solution for 40GBASE-SR4 and 100GBASE-SR4 parallel optical networks. Its female-to-female MPO connectors connect directly between compatible male-interface transceivers or MPO patching systems.
Type B polarity reverses the fiber positions from one end to the other to maintain correct transmit and receive alignment. The cable is available in multiple lengths for data center, spine-leaf and high-density patching applications.

Type B MPO Polarity
Type B polarity reverses the fiber positions from one end of the cable to the other.
This maintains the correct transmit-to-receive alignment required for direct connections between 40G QSFP+ SR4 or 100G QSFP28 SR4 transceivers.
Applications
The 8 fiber MPO OM4 patch cable is designed for parallel optical connections between compatible transceivers and MPO cabling systems in high-density data center networks.
1. 40G QSFP+ SR4 Direct Connection
Provides a direct OM4 multimode connection between two 40G QSFP+ SR4 transceivers.
2. 100G QSFP28 SR4 Direct Connection
Supports short-distance parallel optical links between two 100G QSFP28 SR4 transceivers.
3. High-Density MPO Patching Connects
compatible MPO patch panels for structured cabling between racks or data center zones.
Quality Assurance
Each MPO female to female cable is inspected and tested before shipment to verify connector cleanliness, optical performance and correct Type B polarity.

Polarity Verification FAQ Section
What is an 8 fiber MPO OM4 patch cable used for?
It is used for parallel optical connections in 40GBASE-SR4 and 100GBASE-SR4 networks, including transceiver-to-transceiver and MPO patch panel links.
What is the difference between male and female MPO connectors?
Male MPO connectors have alignment pins, while female MPO connectors have alignment holes. This product uses female connectors at both ends.
What does Type B polarity mean?
Type B polarity reverses the fiber positions from one end to the other to maintain the required transmit and receive alignment.
Are different cable lengths available?
Yes. This MPO female to female cable is available in multiple lengths to meet different rack and data center cabling requirements.
