This single-mode uniboot patch cord packs two OS2 fibers into one round 2.0 mm cable with a shared LC/UPC uniboot connector at each end. It's a space-saving way to connect long-reach optics in dense switch and router faceplates.
The bend-insensitive G.657.A1 glass handles tight routing through cable managers with minimal loss. It suits 10G LR, 100G LR4, and CWDM4 optics that use duplex LC ports, from campus cores to carrier racks. A yellow OFNR riser-rated jacket marks it as single-mode and meets fire code for indoor and vertical runs.
Compact Duplex for Single-Mode Ports
Single-mode routers and switches often pack dozens of LC ports into a small faceplate. Standard duplex zipcords crowd those ports quickly. The uniboot design keeps each connection to a single slim cord, which makes dense single-mode gear far easier to manage.
Long-Reach Optics
OS2 fiber carries 1310 and 1550 nm light with typical cabled attenuation of 0.4 and 0.3 dB/km. 10GBASE-LR and 100GBASE-LR4 reach 10 km, while 100G CWDM4 reaches about 2 km. All of them use duplex LC ports, which this cord connects directly.
Bend-Insensitive G.657.A1
ITU-T rates this G.657.A1 glass for bends as tight as 10 mm. That margin helps when cords turn sharply into vertical managers or across tight rack spaces. It also mates cleanly with standard G.652.D fiber in your patch panels.
Round Cable Handling
A round 2.0 mm jacket bends evenly and resists the twisting that flat zipcords show when coiled. It's easier to dress neatly through managers and keeps a consistent bend radius along the route.
UPC Polish
Both ends use a flat UPC polish with blue single-mode connector bodies. Return loss near 50 dB is typical, which is plenty for Ethernet and transport optics. Keep it off green APC ports.
Where It Fits
This cord works well in core switch racks, router faceplates, and meet-me rooms. It's especially useful where many single-mode links share one panel and space is tight. Fewer, slimmer cords make tracing a circuit much faster during an outage.
• Connectors: LC/UPC uniboot duplex, both ends
• Fiber: OS2 single-mode 9/125 µm, G.657.A1
• Cable: round 2.0 mm, two fibers in one jacket
• Jacket: yellow, OFNR
• Typical uses: 10G LR, 100G LR4, CWDM4 links
Keep the Core Clean
A single-mode core is only about 9 µm wide. Even fine dust can block much of the light. Inspect and clean both LC ferrules before every connection.
