Why LC + APC is the preferred combination
LC connectors are known for their small footprint and secure latch mechanism, while APC polishing delivers exceptionally low back-reflection.
Together, they create a connector that supports:
-
Paneles de conexión de alta densidad
-
Long-distance single-mode transmission
-
Sensitive optical transceivers
-
Stable FTTH signal quality
This is why LC APC connectors are becoming standard in modern access and data center fiber networks.
Designed for 0.9mm tight-buffer fiber
| Tipo de cable | Aplicación típica |
|---|---|
| 0.9mm tight buffer | Pigtails, equipment jumpers, internal fiber routing |
This size allows for compact routing inside ODFs, ONTs, and optical modules, without sacrificing mechanical reliability.
Rendimiento óptico
| Parámetro | Valor típico |
|---|---|
| Tipo de fibra | Monomodo (9/125 µm) |
| Tipo de polaco | APC (8° angled) |
| Pérdida de inserción | ≤ 0,30 dB |
| Pérdida de retorno | ≥ 60 dB |
| Longitud de onda operativa | 1310 nm / 1550 nm |
| Durabilidad del acoplamiento | ≥ 1000 ciclos |
These characteristics make it suitable for PON, FTTH, CATV, and long-haul links where reflection control is critical.
Mechanical and structural design
| Artículo | Especificación |
|---|---|
| Tipo de conector | LC Simplex |
| Fiber Size | 0,9 mm |
| Casquillo | Cerámica de circonio de 1,25 mm. |
| Sistema de cierre | RJ-style LC latch |
| End-face | Pulido en ángulo APC |
| Temperatura de funcionamiento | De –40 °C a +75 °C |
En LC latch allows quick push-pull connection, while the ceramic ferrule ensures precise fiber alignment and long-term stability.
Where this connector is typically used

Preguntas y respuestas profesionales
Q1: Why use APC instead of UPC for LC connectors?
APC polishing provides much higher return loss (≥60 dB), which is important for PON, CATV, and long-distance single-mode links where reflected light can degrade performance.
Q2: Can LC APC connect to LC UPC?
No. APC and UPC have different end-face geometries. Mating them causes high insertion loss and possible ferrule damage.
Q3: Is 0.9mm suitable for outdoor drop cables?
0.9mm is mainly used for indoor pigtails and equipment jumpers. Outdoor FTTH drop cables normally use 2.0mm or 3.0mm jackets with reinforced strength members.
