What is the E2000 connector used for?
Jul 10, 2025
The E2000 connector is a high-performance fiber optic connector primarily used in telecommunications, data centers, medical, aerospace, and high-security applications where signal integrity, safety, and optical performance are critical.
E2000 Connector Overview
| Feature | Description |
|---|---|
| Standard | IEC 61754-15 |
| Polish Types | APC (8° angle, green) and UPC (0°, blue) |
| Insertion Loss | Typically ≤ 0.1 – 0.2 dB |
| Return Loss | ≥ 60 dB (UPC), ≥ 75 dB (APC) |
| Fiber Types | Single-mode and multimode |
| Latch Mechanism | Push-pull with spring-loaded safety shutter |
| Ferrule Diameter | 2.5 mm zirconia ceramic |
What Is the E2000 Connector Used For?
1. High-Speed Telecom Networks
Long-haul and metro fiber optic links
DWDM, CWDM, and OADM systems (thanks to excellent return loss)
Central offices and backbones with strict reflection control
2. CATV and RF-over-Fiber Applications
E2000 APC provides ultra-low back reflection, ideal for analog signals
Maintains high signal fidelity for video and broadcast systems
3. FTTx (Fiber to the Home/Building/Node)
Often used at distribution frames or optical termination points
High reliability in point-to-multipoint PON architectures
4. Medical and Industrial Equipment
Used in imaging devices, laser delivery systems, and diagnostic equipment
Spring-loaded shutter provides eye and equipment safety
5. Military, Aerospace, and Secure Systems
Dustproof and laser-safe due to automatic shutter
High reliability in rugged environments
Common in aerospace communication and secure government networks
Unique Features That Set E2000 Apart
| Feature | Benefit |
|---|---|
| Built-in Safety Shutter | Protects user from laser exposure and prevents dust ingress |
| Spring-Loaded Mechanism | Ensures consistent optical performance and alignment |
| Push-Pull Latching | Quick and secure connection, even in tight spaces |
| Color-Coding | Blue = UPC, Green = APC for easy identification |
| Very Low Back Reflection | Excellent for analog and high-bandwidth digital systems |
Comparison with SC/LC Connectors
| Feature | E2000 | SC/LC |
|---|---|---|
| Shutter Protection | ✅ Yes | ❌ No |
| Return Loss (APC) | ✅ Up to 75 dB | ~60 dB |
| Insertion Loss | ✅ Lower (0.1–0.2 dB) | ~0.3 dB (typical) |
| Cost | ❌ More expensive | ✅ More cost-effective |
| Ruggedness | ✅ Excellent | Moderate |
| Applications | Specialized, critical | General-purpose |
Summary
The E2000 connector is ideal when:
High return loss is critical (e.g., analog video, PON)
Safety (eye protection) and cleanliness (dustproof) are important
Long-term reliability in harsh or sensitive environments is required
