Connector Kits Composition
MPO Connector Kit Component Breakdown
Each MPO connector assembly comprises several precision-engineered components working together. The MT ferrule houses aligned fiber holes for ribbon termination. The connector housing provides mechanical protection and push-pull latching functionality. Internal springs generate controlled force for optimal ferrule face contact. Guide pins (male) or guide holes (female) ensure micron-level alignment during connector mating. The boot strain relief protects against cable bend damage. FOCC supplies these components individually or as complete kits, supporting both standard configurations and custom assemblies for OEM applications.
Housing Color

FAQ
Q: What is the difference between MPO and MTP connectors?
A: MPO (Multi-fiber Push On) is the industry standard connector type defined by IEC 61754-7, while MTP is a trademarked brand name from US Conec representing their enhanced MPO connector design. All MTP connectors are MPO-compatible, and our MPO connector components work with both generic MPO and MTP-brand assemblies. When sourcing components, the key is ensuring compliance with the underlying standards rather than brand names.
Q: How do I choose between male and female MPO connector kits?
A: The selection depends on your mating interface requirements. Male connectors feature guide pins and are typically used on patch panel ports, while female connectors (without pins) connect to equipment transceiver ports like QSFP modules which have built-in pins. For trunk cables, common practice is using female connectors on both ends to interface with adapter panels. Our technical team can advise on the optimal configuration for your specific deployment scenario.
Q: Can you supply custom fiber count MT ferrules beyond standard configurations?
A: Yes, we offer customization services for non-standard MT ferrule specifications. While our standard range covers 8, 12, 24, and 36 fiber configurations, we can manufacture ferrules with alternative fiber counts, modified hole patterns, or special dimensional requirements based on your engineering drawings. Minimum order quantities apply for custom specifications-please contact our sales team with your requirements.

A: Our MPO connector components comply with international fiber optic standards including IEC 61754-7 (MPO connector interface), TIA-604-5 FOCIS-5, and Telcordia GR-1435-CORE for reliability testing. Our manufacturing facility operates under ISO quality management systems, and all ferrules undergo automated dimensional inspection to verify fiber hole position, guide pin hole location, and surface geometry before shipment.
Q: What is the typical insertion loss performance of your MT ferrules?
A: Our standard-grade MT ferrules achieve typical random mating insertion loss of 0.35dB for multimode and 0.50dB for singlemode applications. For demanding data center applications requiring tighter budgets, we also offer premium-grade ferrules with enhanced tolerances achieving typical losses below 0.25dB. All specifications assume proper termination procedures and clean end face conditions.
Q: Do you provide components compatible with APC (angled physical contact) singlemode MPO?
A: Yes, we supply MT ferrules and connector housings designed for 8-degree angled polish (APC) singlemode applications. APC ferrules require matched polarity (key-up to key-down) mating and are commonly used in long-reach singlemode links requiring maximum return loss performance. Our singlemode APC ferrules and yellow-coded housings are available for 12-fiber and 24-fiber configurations commonly used with PSM4 and higher-order singlemode parallel optics.
Q: What color housing options are available for polarity management?
A: We stock MPO connector housings in multiple colors following industry conventions: aqua (OM3/OM4 multimode), violet (OM4 differentiation), yellow (OS2 singlemode), and lime green (OM5). Additional colors including black, white, and custom Pantone-matched options can be produced for OEM orders. Color coding significantly simplifies polarity verification and cable identification during installation and maintenance.
Q: What is your minimum order quantity for MPO connector components?
A: For standard catalog items including MT ferrules, housings, and guide pins, our minimum order quantity is typically 100 pieces per item. Complete connector kits have lower MOQs starting from 50 sets. For custom specifications or OEM private labeling, minimums vary based on the specific requirements-please contact us with your project details for a tailored quotation.
