8-Fiber OM3 MPO Patch Cord, Type B, Female-to-Female
This 8 fiber mpo cable is intended for cabling designs that require eight populated fibers and OM3 multimode transmission. Before selecting this type b mpo patch cable, match its connector format and fiber-position assignment to the equipment interface.

Eight-Fiber Configuration and Connection Matching
Fiber count and connector position numbering are separate considerations. For this 8 fiber mpo cable, confirm which positions are populated rather than assuming a simple position 1-to-8 layout.
Both ends use female MPO/PC connectors without guide pins. The mating interfaces must provide the appropriate pin configuration.
Check this type b mpo patch cable against the complete channel design, including any panels or cassettes, to ensure that the transmitting fibers connect to the intended receiving fibers.

Applications
This om3 mpo patch cord is intended for compatible eight-fiber multimode connections, including:
- Parallel-optics equipment links requiring eight active fibers
- Rack-to-rack patching within an OM3 channel design
- Connections through compatible eight-fiber MPO patching systems
- OFNP-specified cabling routes in data center installations
40GBASE-SR4 and 100GBASE-SR4 use four transmitting and four receiving fibers. Before selecting this 8 fiber mpo cable for either application, verify the populated connector positions, gender, polarity, channel loss and supported OM3 distance. Eight fibers alone do not establish compatibility.

End detectionQ1: Why select an 8 fiber mpo cable instead of a 12-fiber assembly?
Select it when the equipment and cabling design specify eight populated fibers. Confirm the required connector positions and any panel or cassette connections before substituting it for a 12-fiber assembly.
Q2: Does an eight-fiber cable always use positions numbered 1 to 8?
No. Fiber count does not by itself define the connector’s position numbering. Check the assembly drawing for the populated positions and end-to-end mapping.
Q3: Does this type b mpo patch cable provide a breakout connection?
No. This product has MPO connectors at both ends. A connection to separate LC ports requires an appropriately specified breakout cable or cassette.
Q4: What determines the operating distance of this om3 mpo patch cord?
The selected transceivers, total channel length and channel loss determine the supported distance. Use the equipment manufacturer’s OM3 specifications rather than assigning one distance to every application.
