UnitekFiber's 72Fibers micro indoor distribution fiber optic cable is engineered for high density indoor fiber optic networks. Its design features fibers arranged into subunits, encased within an Aramid yarn and OFNR riser rated jacket, which is Intended for vertical runs between floors in riser spaces. By utilizing 250um bare fibers instead of thicker 900um tight buffered fibers, the indoor micro distribution fiber optic cable achieve a significantly smaller 8.5m outside diameter while maintaining high fiber counts. The ultra compact design reduces bulk, making the mini indoor distribution fiber optical cables ideal for tight conduit spaces and high density patching cabling. Perfect for rack systems and high density patching where hundreds of connections must be managed in a small footprint, like data center, Intra-Building Backbones, FTTx or etc.

The mini indoor distribution fiber optic cable features a compact 8.5mm outer diameter, integrating up to 72fibers within a small cable structure, each subunits with 12fiber, totally 6subunits. Compared with 0.9mm tight buffer indoor optical fiber cables, the micro fiber cable design occupies less space, reduces cable congestion, and improves overall fiber management efficiency. With high density design, the micro indoor fiber optic cable allows for easier routing, installation, and maintenance in high density environments such as data centers, enterprise networks, and MTP/MPO modular connectivity systems.
The mini indoor fiber optic cable is engineered with Corning® SMF-28® Ultra fiber, delivering excellent bend performance and reliable optical transmission. Its superior bend radius capability allows the indoor fiber optical cable to easily adapt to tight bends and narrow, high density cabling spaces, helping reduce signal loss caused by challenging installations. Meanwhile, the micro fiber optical cable support heavy data traffic and modern high speed systems by using Corning® SMF-28® Ultra fiber.
The OFNR rated jacket of the mini indoor fiber optical cable is designed to meet the fire safety requirements of indoor riser cabling. It provides enhanced flame resistance and helps limit flame extended along vertical space, making it suitable for installation in building risers, vertical shafts, and other indoor areas where fire performance is a critical consideration.
As a professional fiber optic cable supplier, UnitekFiber offers multiple jacket material options, including PVC, OFNP, and flame retardant LSZH. With flexible customization capabilities, we can provide suitable indoor fiber optical cable that compliance with requirement.

The micro indoor optical fiber cable is optimized for MTP/MPO pre-terminated cabling solutions, providing an efficient fiber cabling option for high density data center. By supporting pre-terminated connectivity solutions, this indoor mini fiber optic cable enables quick installation, reduces field termination time, and simplifies cable management in complex fiber infrastructures. The lightweight and flexible structure helps improve routing efficiency, minimize cable congestion, and maintain organized fiber pathways within high density racks.

Yes. The mini indoor fiber optic cable is designed for today's high bandwidth optical communication systems. Combined with Corning® SMF-28® Ultra fiber, it supports high speed transmission for applications including 10G, 25G, 40G, 100G, 400G, and future data center network upgrades.
Yes. UnitekFiber provides OEM and ODM customization services for mini indoor fiber optic cables, including fiber glass, fiber core, jacket material, jacket color or etc.
Unlike 900um tight buffered fiber optic cables, this mini distribution cable uses 250um bare fibers into subunits. It significantly reduces the cable diameter.
This indoor fiber optic cable is widely used in Data centers, Enterprise backbone networks, Building backbone cabling, FTTx networks, MTP/MPO structured cabling, High density patching environments, Telecommunications equipment rooms or etc.
OFNR is a flame rated cable jacket designed for vertical riser installations inside buildings. It helps reduce flame propagation between floors and complies with fire safety requirements for riser spaces, making it suitable for building backbones, equipment rooms, and telecommunications closets.
Multiple jacket options are a huge plus for our diverse projects. We ordered LSZH for indoor public areas and OFNR version for vertical riser wiring, all meet UL compliance requirements with stable quality.
Genuine Corning SMF-28 Ultra fiber is trustworthy. The transmission performance is stable for both 1310nm and 1550nm wavelengths, supporting our 10G network operation perfectly with no packet loss or signal jitter.
Lightweight and ultra-compact design greatly reduces construction difficulty. Our workers can handle and lay the cable effortlessly, even in confined ceiling and pipe spaces. Greatly shorten the project construction cycle.
Easy stripping and processing! The outer jacket and subunit tubes are easy to peel without damaging internal bare fibers, which is very friendly for on site splicing and terminal production.
