SN Patch Cable
Primary Usages and Applications
1. High-Density Data Center Switching
CS connector is significantly smaller than the standard LC connector (about 40% smaller), it allows for double the port density on patch panels and switches.
2. QSFP-DD and OSFP Transceivers
CS cables are the go-to for breakout applications involving high-speed transceivers.
3. Structured Cabling Upgrades
For enterprises looking to upgrade their bandwidth without physically expanding their floor space or rack footprint, CS cables allow them to replace older LC systems. This "more fiber, less space" approach is vital for edge computing and colocation facilities.

The differences between Single-Mode Fiber (SMF/OS1/OS2) and the various Multi-Mode Fiber (OM1, OM2, OM3, OM4,OM5) grades.
Grade | Core Size | Jacket Color | LED-Optimized | Laser-Optimized (850nm VCSEL) | Key Feature & Typical Use |
SM | 8-10 µm | Yellow | \ | \ | Long-distance: Telecom, ISP backbones, CATV, MANs (10s to 1000s of km). |
OM1 | 62.5 µm | Orange | 200 MHz·km | Not supported | Legacy installations (1990s). Limited to 1 Gigabit up to ~275m. |
OM2 | 50 µm | Orange | 500 MHz·km | Not supported | Basic 1 Gigabit Ethernet up to ~550m. Being phased out. |
OM3 | 50 µm | Aqua | Not primary | 1500 MHz·km | First laser-optimized (LOMMF). 10 GbE up to 300m. Standard for modern 10G data centers. |
OM4 | 50 µm | Aqua | Not primary | 3500 MHz·km | Enhanced OM3. 10 GbE up to 400m, 40/100 GbE up to 150m. High-speed data center backbone. |
