KCO Fiber factory directly sell Single Mode 8fibers APC MPO-8 MTP-8 To LC Duplex Fiber Optical Break-out Patch Cable
Option 1: MPO-8 APC connector + mini cable SM G657A1 8F + LC/UPC Duplex connector
Option 2: MTP-8 APC connector + mini cable SM G657A1 8F + LC/UPC Duplex connector

Fiber Mapping: Fiber 1 connects to Fiber 1 (LC), Fiber 2 to Fiber 2, and so on.
Key Orientation: Key-Up to Key-Down.
How it works: Because this maintains a straight-through path, the Tx → Rx flip must happen somewhere else in the network. To complete the circuit, you must use a standard A-to-B (Crossover) LC duplex patch cord at one end (e.g., at the switch/transceiver).
Fiber Mapping: Fiber 1 connects to Fiber 12 (LC), Fiber 2 connects to Fiber 11, and so on.
Key Orientation: Key-Up to Key-Up.
How it works: This creates an inherent flip within the cable itself. Because of this internal reversal, you must use a Straight-Through A-to-A LC patch cord to maintain the correct Tx → Rx orientation.
Fiber Mapping: Fiber 1 connects to Fiber 2 (LC), Fiber 2 to Fiber 1, Fiber 3 to Fiber 4, and so on.
Key Orientation: Key-Up to Key-Down.
How it works: The pair-flip naturally maps Tx to Rx from end to end, making it ideal for connecting directly to duplex LC equipment without needing any special crossover patch cords. You use standard A-to-B LC patch cords on both ends.
