Introduction to the Optical fiber connectivity

AI data center is keep improving, optical transceivers receptacle type is also keep updating, the fiber connector for it is also evolving. We are upload the latest optical fiber connector type in this blog.

Duplex Conectors

LC: Lucent connector, it is 1.25mm ferrule and available in simplex
MDC: It is a VSFF (Very Small Form Factor) connector
– 1.25mm ferrule
– Native duplex
3x fiber cabling density over LC connectors, providing 216 duplex connectors (432 fibers) within 1 RU, simple polarity reversal with no exposed fibers. It supports Single-mode PC and APC polishing, Multimode (OM3, OM4, and OM5) available.

SN: It is a VSFF connector
– VSFF
– 1.25mm ferrule
– Native duplex

CS: It is a VSFF connector
– VSFF
– 1.25mm ferrule
– Native duplex

Base-8/12 Connectors


MPO-8
– Multi-fiber push on
– Single row 8 fibers
– Alignment pins

MPO-12
– Multi-fiber push on
– Single row 12 fibers
– Alignment pins

MMC-12: It is a VSFF connector, with single row 12 fibers and alignment pins
MMC connector enables deployment of next-generation, high-density, multi-fiber cabling solutions, by combining a novel, reduced footprint multi-fiber ferrule with a very small Form factor connector footprint which is 1/3 the size of the MPO format.

Base-16 Connectors


MPO-16
– Multi-fiber push on
– Single row 16 fibers
– Alignment pins

SN-MT-16: It is a VSFF connector with single row 16 fibers and Alignment pins
The SN-MT is a revolutionary Very Small Form Factor (VSFF) connector with 2.7 times the density of MPO connectors. The SN-MT incorporates a single, compact SN.-MT ferrule and is compatible with next-generation 200 μm rollable ribbon cables.

MMC-16: It is a VSFF connector, with single row 16 fibers and Alignment pins

Base-24 Connectors


MPO-24
– Multi-fiber push on
– Double row 12 fibers
– Alignment pins

SN-MT-24: It is a VSFF connector, it is 2.7 x denser than MPO, wiht double row 12 fibers and alignment pins

MMC-24: It is a VSFF connector, it is 24 fiber with two rows of 12 fiber, similar to SN-MT-24 and MPO-24, it requires alignment pins also, it is roven standard 24-MT mechanical and fiber alignment structure, supports ganged insertion applications
