CLIFF Electronics Adds Two-Port MMC Connector To Their Ever-Growing Feedthrough Range

US Conec® MMC 2-port female to MMC 2-port female.

APC VSFF multi-fibre multi-fiber optical connectors for TMT ferrules.

 

 

The new US Conec® MMC is a Very Small Form Factor (VSFF) multi-fibre multi-fiber optical connector that has been designed for terminating multiple single-mode and multi-mode optical fibre fiber cables in AI, cloud, and large data centre center environments.

 

The two-port MMC feedthrough connector accepts one or two US Conec® APC-polished connectors and is supplied with two single-port dust covers on the front and two on the rear.

 

The keystone coupler can be assembled in any of CLIFF’s feedthrough frames upon request and is initially offered in the following options:

MMC optical female to female slim metal front or rear mounting feedthrough connector CP30744M...

 

Applications include:

  • Data Centres Centers - high-density optical connections for server racks and patch panels, multi-fibre multi-fiber breakout in top-of-rack and middle-of-row configurations and for hyperscale environments where space is critical.
  • Cloud Infrastructure - backbone and interconnect solutions in cloud storage networks, supporting fast deployment with scalable fibre fiber distribution systems and compatible with VSFF architectures.
  • AI / Machine Learning Clusters - fibre-optic fiber-optic backbone for GPU-based compute clusters, high-bandwidth interconnections between AI training nodes and low-latency connections for real-time data processing.
  • Enterprise Networks - future-proofed fibre fiber connectivity in modern office buildings, integration into structured cabling systems and suited for fibre-to-the-desk fiber-to-the-desk (FTTD) or high-density patch panels.
  • Telecom and ISP Equipment - multi-fibre multi-fiber solutions for central offices, PoPs or Edge networks with scalable port density for broadband expansion and ready for 5G and next-gen fibre fiber rollout.
  • Test and Measurement Equipment - optical interface access in laboratory instrumentation, modular setup for R&D environments or production testing and supporting quick changes in fibre fiber topology without rework.

 

Single-mode and multi-mode optical fibre fiber cables in AI, cloud, and large data centre center environments...

 

The new CLIFF two-port MMC feedthrough connector offers many advantages:

  • Accepts one or two US Conec® MMC APC connectors.
  • Supports multi-mode and single-mode.
  • Enables high-density, low-footprint connectivity.
  • Mountable in XLR-format or DualSLIM panels (modular installation).
  • Supplied with front and rear dust covers for port protection.

 

Two Port MMC feedthrough connectors available from CLIFF Electronics.

 

CLIFF’s standard and DualSLIM feedthrough ranges now provide analogue, digital and optical connectivity in formats including

  • BNC (50 or 75 ohm),
  • DisplayPort,
  • HDMI,
  • Optical fibre fiber (FC, LC Duplex, SC Simplex, ST BFOC, TOSLINK and US Conec MTP® brand MPO),
  • RCA phono, phono / cinch,
  • RJ45 ethernet (UTP or FTP) in Cat6, Cat6a or Cat5e,
  • USB 2,
  • USB 3 and
  • USB-C.

 

CLIFF’s feedthrough connectors are available direct or from international distributors.

 

 

Quality has always been of prime importance.
