Designed in accordance with IEC 61755 and IEC 61754 standards, the TMT ferrule ensures precise alignment for MT and MT-16 configurations. Its 250μm pitch fiber holes accommodate standard 250μm OD single-mode and multimode fibers, as well as reduced OD fibers such as 200μm and 165μm.

MMC Jr.

The compact footprint of the MMC Jr. connector ensures a secure and reliable connection while conserving valu-able space in space-constrained environments. It is optimized for use in fiber optic transceivers, on-board optics, module cassettes, and data center interconnect applications.

MMC Adapter

MMC adapters are available in multiple port configurations, including versions that support direct mating be-tween MMC and MMC Jr.connectors. The 2-port adapter fits standard MPO cutouts, enabling a straightforward upgrade from MPO to MMC with double the port density. For higher-density applications, 4-port and 6-port op-tions are also available. Optional port covers are offered to block unused ports when needed.

MMC Interface Shuffle Enclosure

Modern hyperscale data centers demand ultra-high-speed parallel optical connections, but traditional spine-leaf architectures create cabling complexity—each leaf switch must connect to every spine switch, leading to tangled fiber bundles and inefficient layouts. T&S’s 4U Shuffle Enclosure with FOFC (Fiber Optic Flex Circuit) Technology overcomes this challenge in a revolutionary way:
