Descrição
Duplex structure — keeping transmit and receive always paired
Single-mode systems depend on precise bidirectional paths.
With the duplex LC housing, both fibers remain locked together, preventing polarity mistakes when connecting:
-
Switch ↔ switch
-
Router ↔ router
-
OLT ↔ distribution frame
-
Server ↔ storage system
Even during maintenance, the link stays organized and traceable.
Why 2.0mm is the standard for active equipment
The 2.0mm jacket is the industry balance point between flexibility and protection.
| Jacket size | Behavior in real networks |
|---|---|
| 0,9 mm | Too fragile for live patching |
| 2,0 mm | Perfect for switches, panels & transceivers |
| 3,0 mm | Over-engineered for rack ports |
It bends easily behind LC adapters while still protecting the fiber from micro-bending and handling stress.
Desempenho óptico
| Parâmetro | Typical value |
|---|---|
| Fiber type | Modo único 9/125 µm |
| End face | UPC |
| Insertion loss | ≤ 0,30 dB |
| Return loss | ≥ 50 dB |
| Operating wavelengths | 1310 / 1550 nm |
| Durabilidade | ≥ 1000 matings |
These values support Ethernet, SDH, DWDM and access networks with long-term stability.
Engineering inside the connector
| Part | Role |
|---|---|
| 1.25mm zirconia ferrule | Keeps fiber core perfectly aligned |
| Precision UPC polish | Reduces Fresnel reflection |
| Duplex LC latch | Maintains Tx/Rx orientation |
| 2.0mm strain-relief boot | Prevents bending and pull damage |
Perguntas e respostas profissionais
Can LC UPC duplex be used for long-distance single-mode links?
Yes. It is widely used in backbone, metro and data center links where low loss and stable mating are required.
Is UPC compatible with APC adapters?
No. UPC must only be connected to UPC. Mixing UPC and APC will damage the ferrules and degrade performance.
Why is duplex preferred over two simplex connectors?
Duplex ensures correct polarity, faster installation and cleaner cable management in professional networks.
