Customization Options
We understand that every network infrastructure has unique requirements. The following customization options are available for MPO-ST breakout cable fiber optic assemblies:
Cable Length Configuration
Trunk lengths from 1m to 100m; breakout leg lengths from 0.3m to 5m; specify exact dimensions for rack and cabinet layouts
Fiber Type Selection
OM3 (300MHz·km), OM4 (4700MHz·km), OM5 (wide-band multimode), or OS2 single-mode (9/125µm) for long-distance applications
Fiber Count Options
8-fiber, 12-fiber, or 24-fiber configurations; other counts available for specialized applications
Connector Variations
MPO with or without guide pins; female or male; key up or key down orientation; ST, SC, LC, or FC terminations on breakout legs
Polish Type
UPC (Ultra Physical Contact) standard; APC (Angled Physical Contact, 8°) available for single-mode versions requiring higher return loss
Jacket Materials
LSZH (low smoke zero halogen) for general indoor use; OFNP (plenum-rated) for air-handling spaces; OFNR (riser-rated); PVC for cost-sensitive applications; outdoor-rated armored jackets with UV resistance
Color Coding
Standard TIA-598C colors (Aqua for OM4, Orange for OM2/OM3, Yellow for OS2); custom jacket colors for network identification; color-coded breakout legs matching fiber position
Labeling & Marking
Custom cable tags with circuit IDs, location codes, or asset numbers; sequential numbering on breakout legs; facility-specific labeling schemes
Breakout Configuration
Furcation tube diameter options (900µm or 2.0mm); breakout boot styles; staggered vs. grouped breakout for cable management; zip-cord style dual-fiber breakout
