What is the density advantage of MDC over LC?

MDC connectors offer 3 times the density of LC duplex connectors. In a standard 1RU panel, MDC supports up to 36 duplex ports (72 fibers) vs. 12 ports (24 fibers) for LC.

Can MDC connectors be polarity-reversed?

Yes, MDC connectors with DirectConec push-pull boot design support tool-free polarity reversal by rotating the connector body 180 degrees.

What is the maximum data rate supported by MDC?

MDC connectors support transmission rates up to 400Gbps, making them suitable for next-generation AI data center and high-speed network deployments.

AI-Powered supplier vetting

SummaryShenzhen Kexint Technology Co., Ltd. is a China-based limited company established in 2015 with 53 employees and affiliated companies. Its product scope includes ONU, fiber cable, fiber optic patch panels, and fiber optic distribution boxes. The supplier demonstrates strong quality-control procedures, including 100% finished-product inspection, six quality inspectors, and documented inspection instructions. It offers broad customization and has an available SDK, but reports no new products in the past year, no ODM service, and no OEM service for popular brands. Service procedures, complaint handling, and corrective/preventive actions are documented and followed. Inventory capability and stated lead times within 15 working days are positive, while the lack of a valid manufacturing-capacity contract with related subcontractors, overseas warehouse, and overseas showroom represent operational limitations. Financial records are indicated for multiple years, but no financial figures or performance results are...

Supplier typeThe supplier is identified as a combined business entity and a limited company operating in China, with 53 employees, affiliated companies, and product offerings in optical-networking equipment and fiber products. This establishes a defined legal and operating profile, although its general trade-volume range is unknown.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints, and it has inventory capability. However, it lacks overseas warehouse and showroom capabilities; the evidence supports domestic or general service-process capability but does not establish comprehensive overseas after-sales coverage.

Production capacityThe supplier offers fiber cable and related optical-networking products, has 100% finished-product inspection, six quality inspectors, documented inspection instructions, inventory capability, and stated lead times within 15 working days in both peak and off-season. Production-capacity risk remains because there is no valid manufacturing-capacity contract with the factory and related subcontractors.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. These capabilities are consistently reported across quality/design and R&D information, although no specific customized project examples are provided.

Product Q&A

Q:What is an MDC connector?

MDC (Miniature Duplex Connector) is a Very Small Form Factor (VSFF) fiber optic connector that provides duplex connectivity in a compact footprint. It delivers up to 3 times the density of LC connectors in the same rack space.

Q:What is the difference between APC and UPC polish?

APC (Angled Physical Contact) has an 8 degrees angled endface, providing higher return loss than UPC . APC is preferred for high-precision and high-speed applications.

Q:What is G.657.A1 bend-insensitive fiber?

G.657.A1 is a bend-insensitive single-mode fiber with a minimum bend radius of 10mm, allowing flexible routing in tight spaces without significant signal loss.

Q:What is LSZH jacket and why is it important?

LSZH (Low Smoke Zero Halogen) is a flame-retardant cable jacket that emits minimal smoke and no toxic halogen gases when burned, making it essential for indoor data centers and public buildings.

Q:Is MDC compatible with existing LC infrastructure?

MDC connectors are not compatible with LC ports. However, MDC maintains a similar latch mechanism and is compatible with most LC assembly tools, making the transition from LC to MDC relatively smooth.
