DESCRIPTION
The FOCC MMC-16 Fiber Optic Jumper is an ultra-compact, high-performance cable designed for next-generation 400G/800G optical interconnects.
Equipped with US Conec MMC connectors on both ends, this VSFF jumper triples port density compared to traditional MPO/MTP systems while maintaining exceptional optical precision.
Featuring the DirectConec push-pull boot, it ensures effortless operation in tight spaces. The use of TMT Elite ferrule technology guarantees low insertion loss and high return loss across both OM4 multimode (Magenta) and OS2 single-mode (Yellow) variants.
Engineered for reliability, scalability, and safety, MMC-16 jumpers redefine density and efficiency in modern data center cabling.

● Inter-rack or intra-rack patching for modular panels and cassettes.
● Space-constrained environments requiring ultra-compact VSFF connectors.
● Telecom and backbone optical links in intelligent data infrastructures.
● Test and R&D labs requiring repeatable high-precision optical connections.
FEATURE
● Very Small Form Factor (VSFF) MMC connector offers 3× the port density of MPO.
● DirectConec push-pull boot enables tool-free insertion and extraction.
● TMT Elite ferrule guarantees ≤0.35 dB low insertion loss and high APC return loss.
● Compatible with MT/MT-16 mechanical alignment structures.
● Available in OM4 (Multimode) and OS2 (Single-Mode) fiber types.
● Plenum (OFNP) flame-retardant jacket for safe use in air-handling spaces.
● Lightweight 2.5 mm bend-insensitive fiber with 7.5–10 mm minimum bend radius.
● Factory pre-terminated and 100 % IL/RL tested for consistent performance.

FAQ
What is an MMC connector?
The MMC is a Very Small Form Factor (VSFF) connector from US Conec that provides 3× the port density of traditional MPO interfaces.
What's the difference between OM4 and OS2 versions?
OM4 is a multimode fiber for short-reach, high-bandwidth links, while OS2 is a single-mode fiber for long-distance transmission.
Is this compatible with MTP/MPO connectors?
Not directly. MMC and MPO use different interfaces, but hybrid MMC-to-MTP cables are available for migration applications.
What is the typical insertion and return loss?
Insertion loss ≤ 0.35 dB (max) and return loss ≥ 40–60 dB depending on fiber type and polish.
Can I order custom lengths or colors?
Yes. Lengths, colors (Magenta, Yellow, Aqua etc.), and labeling can be customized to your project requirements.
What jacket rating does it use?
Plenum (OFNP), compliant with building fire safety standards for indoor air-handling spaces.
Does HOLIGHT offer OEM/ODM service?
Yes. We provide OEM/ODM options including logo printing, private labeling, and special packaging.
How is each jumper tested before shipment?
Each assembly is individually tested for insertion loss, return loss, and visual end-face inspection to ensure consistent performance.
