Data Center Connectivity

Fiber Optic Data Center Connector
Duplex LC Connector & MDC Connector

Best Datacom’s Fiber Optic Systems are designed for Enterprise Data Centers, Cloud, Managed Facilities, and Government Data Centers.

We specialize in high-performance Fiber Optic assemblies and components that work on Open and proprietary platforms.

Best Datacom features MTP, LC, and MDC connectivity.

The data center industry is experiencing unprecedented growth and innovation.

Driving this growth is a need to support the rapid transmission of data.

This requires faster transceiver technology, future-ready physical infrastructure, cabling and connectivity, and simplified network architectures.

Fiber optic connectors play an important role in this transition.

The LC and MPO/MTP connectors are now standard for data centers.

Scalable Platform: MDC Ganged Variants (8f & 4f)

MDC & SN Connectors Overview

MDC & SN connectors are new Mini Duplex Connectors designed for Data Center 400G optimization.

Simplicity of design and fewer components provide a multi-generational lifecycle.

Very Small Form Factor Connectors (VSFFC) provide individual and multiple breakouts at the transceiver (QSFP, QSFP-DD, SFP) providing a more efficient, reliable, and lower cost alternative than the LC or MPO connector.


Installation Advantages

Advantages are faster error free installation and polarity changes that can be quickly done in the field.

This is something that is not possible with MPO connectors.

Insertion and extraction of the MDC connector is done with a simple push or pull on a flexible and robust strain relief boot providing functional density in very tight spaces.


Stability Advantages

MDC & SN connectors are designed for optimal stability exceeding the requirements of Telcordia GR-326 for carrier or data center applications.

This solution reduces installation and operating costs throughout its life of service.


High Density MDC & SN Connectors

 High density MDC & SN connectors have two LC 1.25mm ceramic ferrules in a single housing, pitched 3.1mm apart vs 6.25mm in duplex LC connectors.

Each connector ferrule is prepared, polished, and tested.

This permits the manufacturer to easily maintain high performance for fiber connections and the use of the widely deployed LC ferrule allows for a simple and streamlined manufacturing process.

In comparison, MPO connectors have 12 fibers terminated into one ferrule.

MPO’s are difficult to prepare, polish, and test and are done for all fibers simultaneously resulting in varying performance of each of the fiber connections.


MDC & SN Duplex Connectors

MDC & SN duplex connectors can be ganged in groups of 2, 3, and 4. MDC adapters fit directly into standard panel openings increasing fiber density by a factor of three.

Port breakout architectures allow for a single transceiver to accept multiple MDC patch cables that are individually accessible directly at the transceiver interface.

The format supports four MDC cables in a QSFP footprint and two MDC cables in a SFP transceiver.
