DESCRIPTION
The FOCC MMC-16 to 2×MTP-8 Breakout Cable is a next-generation VSFF (Very Small Form Factor)interconnect designed for high-density 400G/800G systems.
By combining an MMC-16 connector on one end with two MTP-8 connectors on the other, it efficiently consolidates parallel channels while maintaining outstanding optical performance.
With DirectConec push-pull boots, TMT Elite ferrules, and a plenum-rated flexible jacket, this cable minimizes space usage, simplifies installation, and delivers reliable performance in demanding data-center and telecom environments.
APPLICATIONS
● 400G/800G parallel transmission for QSFP-DD, OSFP, and DR8/DR4 optical modules.
● High-density structured cabling in hyperscale and enterprise data centers.
● Inter-rack or intra-rack breakout between MMC panels and MTP-8 modules.
● Modular patch panels and cassette systems requiring compact VSFF connections.
● Telecom and central office backbone cabling where space and performance matter.
● Testing, monitoring, and validation of parallel fiber networks.
FEATURE
● VSFF MMC connector provides 3× higher port density than MPO systems.
● Combines two MTP-8 ports into one MMC-16 interface for space efficiency.
● DirectConec push-pull boot allows effortless one-hand insertion and removal.
● TMT Elite ferrule ensures ≤0.35 dB low insertion loss with superior APC/UPC return loss.
● Available in OM4 (Multimode) and OS2 (Single-Mode) fiber types.
● Fully compliant with Telcordia GR-1435 and IEC 61754-36 standards.
● Plenum-rated (OFNP) jacket for safe in-ceiling and raised-floor installations.
● Factory-terminated, 100 % IL/RL tested, ready for plug-and-play deployment.
