Description
🛠️ Key Benefits for Legacy System Upgrades
- 100% Retrofit Compatibility: Works with all ST/UPC adapters and legacy multimode fiber (OM1/OM2/OM3), making it ideal for upgrading factory automation, HVAC control, and security camera systems.
- Vibration-Resistant Locking: The bayonet twist-lock design provides a secure connection that withstands mechanical vibration—critical for industrial floors and outdoor equipment cabinets.
- Low Learning Curve: Technicians familiar with legacy ST systems can install/repair without additional training, reducing labor costs for retrofits.
- Proven Durability: Built to industrial-grade standards, it withstands ≥1800 mating cycles and operating temperatures from -20°C to +70°C, ensuring reliability in harsh environments.

🏭 Legacy & Industrial Applications
- Factory Automation: Connects PLCs, sensors, and robotic arms in manufacturing plants with legacy ST-equipped controllers.
- Older Office Buildings: Upgrades 100Mbps/1Gbps networks to 10Gbps without rewiring (compatible with existing ST patch panels).
- Security Systems: Supports analog-to-IP camera upgrades, maintaining connectivity with legacy ST fiber backbones.
- Utility Networks: Powers smart meter and grid control systems in infrastructure deployed before LC/SC became standard.
❓ Retrofit-Focused FAQ
Q1: Can we use ST-MM pigtails to connect legacy OM1 fiber to new OM4 switches?
A: Yes—ST-MM pigtails are backward-compatible with OM1/OM2 fiber and forward-compatible with OM3/OM4 switches. Note that transmission distance will be limited by the oldest fiber type (e.g., 10Gbps over 275m for OM3, 33m for OM1).
Q2: How do we identify if our existing system uses ST connectors?
A: ST connectors have a round ferrule (2.5mm diameter) and a bayonet-style locking ring—look for a “twist-to-lock” mechanism (vs. push-pull for SC or latch for LC).
Q3: Is the ST-MM pigtail suitable for outdoor retrofits?
A: Yes—the heavy-duty LSZH jacket resists UV radiation and moisture. For direct burial or extreme weather, pair it with a waterproof ST adapter (sold separately) for IP67 protection.
