Technical Specs That Move Data
For the network architect, the numbers tell the story. Here is the 2026 performance profile for a premium LC/UPC Simplex jumper:
| Métrique | Spécifications | Valeur d'ingénierie |
| Type de connecteur | LC/UPC à LC/UPC | High-density “Snap-in” latching |
| Noyau de fibre | Mode unique (OS2) 9/125μm | Optimized for 1310nm & 1550nm |
| Perte d'insertion | $\leq 0.2 \text{ dB}$ | Industry-leading low power loss |
| Perte de retour | $\geq 50 \text{ dB}$ | Crystal clear digital signal |
| Matériau de la veste | LSZH (Jaune) | Fire-safe, low-smoke, zero halogen |
| Rayon de courbure | 10mm – 30mm | Flexible for tight cable management |
Why This Cable is a Network Essential
1. High-Density Ready
The “Small Form Factor” (SFF) design is the biggest selling point. You can stack these side-by-side in high-density ODFs (Optical Distribution Frames) without the “cable spaghetti” associated with larger connectors.
2. The “Click” of Confidence
The LC connector uses a familiar RJ45-style latching mechanism. You don’t need to guess if the connection is secure; that audible “click” tells you your light path is locked in.
3. Future-Proofed OS2 Fiber
While you might be running 1Gbps today, the Single Mode OS2 core inside this cable is rated for 10G, 40G, and even 100G+ speeds over long distances. It’s a “buy once, upgrade never” infrastructure investment.
4. Simplex Efficiency
Simplex (SX) cables are the lean choice for BiDi (bidirectionnel) setups. By using a single strand for both TX and RX, you halve your cabling footprint and simplify your inventory.
Field Guide: Frequently Asked Questions
Q: Can I use this Blue (UPC) cable in a Green (APC) port?
A : Definitely not. A UPC connector has a flat end-face, while an APC port is angled at 8 degrees. If you force them together, you’ll get an air gap that results in massive signal loss and potential physical damage to your equipment. Blue stays with Blue.
Q: Is there a difference between the yellow and aqua cables?
A : Yes! Yellow is the universal code for Mode unique (SM), which is what this LC/UPC-SM-SX cable uses. Aqua is typically used for Multimode (OM3/OM4). You cannot mix the two fiber types.
Q: Does the “Simplex” design limit my speed?
A : Not at all. The speed is determined by your transceivers (SFPs). A single fiber strand can carry massive amounts of data; “Simplex” just means you only have one physical lane of glass.
Q: How often should I clean the LC tips?
A : Every single time you plug it in. Because the LC ferrule is so small (1.25mm), even a microscopic speck of dust can block the entire 9-micron fiber core. Use a “One-Click” cleaner for the best results.
