Rosenberger Optical Solutions & Infrastructure (Rosenberger OSI) has expanded its connector portfolio with the introduction of the Miniature Multifibre Connector (MMC), a Very Small Form Factor (VSFF) solution designed for high-density fibre-optic cabling.
The MMC connector addresses the growing bandwidth requirements of modern data centres, telecommunications networks, 5G infrastructure and FTTx deployments, supporting migration to 400G, 800G, 1.6T and future 3.2T network speeds.
Compact design for higher port density
The MMC connector features an ultra-compact form factor that is smaller than conventional multi-fibre connectors such as MPO. This compact design allows a greater number of fibres to be accommodated within the same panel space, increasing port density in patch panels and active networking hardware.
A push-pull locking mechanism ensures secure connection and easy removal even in installations with very high port density.
High-performance optical characteristics
As a VSFF multi-fibre array connector, the MMC uses Tiny MT ferrules (TMT) and is available in several configurations:
- 1×12 fibres
- 2×12 fibres
- 1×16 fibres
The ferrules feature a 250 µm pitch and support both singlemode and multimode fibres, manufactured to Elite quality standards.
An 8° APC polish enables high return loss values of up to 60 dB for single-mode applications, while insertion loss remains low at 0.35 dB, complying with IEC 61300-3-4 requirements.
The connector also supports at least 500 mating cycles, ensuring stable optical performance throughout its operational lifecycle.
Durable construction for network infrastructure
Despite its miniature size, the MMC connector is designed for reliability in demanding environments. Key mechanical features include:

Durable construction for network infrastructure
Despite its miniature size, the MMC connector is designed for reliability in demanding environments. Key mechanical features include:
- Robust housing with central cable support
- Integrated strain relief and kink protection
- Compatibility with round cables of 2.0–2.5 mm diameter
- Operating temperature range of –40 °C to +75 °C
These characteristics make the connector suitable for data centres and telecommunications infrastructure installations.
Supporting high-speed network migration
Rosenberger Optical Solutions & Infrastructure offers the MMC connector as part of a broader cabling ecosystem that includes patch cables, fan-out cables and trunk cabling solutions.
These products are designed to support gradual network upgrades toward 800 Gbit/s and higher-speed applications, enabling scalable and future-ready fibre-optic infrastructures.
The MMC connector also complies with Telcordia GR-1435 standards for reliability and performance in telecommunications networks.
