Carrier-Grade Singlemode Fiber Pigtail for FTTH, PON and Low-Reflection Optical Networks

The E2000/APC SM G657.A2 Simplex LSZH Yellow Fiber Optic Pigtail is designed for carrier access networks, FTTH deployments, GPON and XGS-PON infrastructure, CATV systems, and other reflection-sensitive optical transmission environments.

Featuring an E2000/APC connector, bend-insensitive G657.A2 singlemode fiber, simplex construction, and an LSZH (Low Smoke Zero Halogen) jacket, this fiber pigtail provides a reliable termination solution for fiber distribution frames, optical terminal boxes, splice closures, and telecom equipment connections.

The integrated shutter mechanism of the E2000 connector helps protect the ferrule end face from contamination when disconnected, making it particularly suitable for high-density fiber distribution systems and operator-grade network environments where connector cleanliness and long-term reliability are essential.

Product Positioning

Carrier-Grade Fiber Pigtail for Critical Optical Infrastructure

This product is positioned for telecom operators, broadband service providers, network integrators, and fiber infrastructure contractors that require stable optical performance, low-reflection connectivity, bend-insensitive routing, and enhanced connector protection.

Compared with conventional fiber pigtails, the E2000/APC G657.A2 pigtail offers several important advantages:

• Integrated E2000 automatic shutter protection
• APC 8° angled polish for reflection-sensitive applications
• G657.A2 bend-insensitive fiber for space-constrained installations
• LSZH jacket suitable for indoor and safety-conscious environments
• Industry-standard yellow jacket for singlemode fiber identification

Key Features and Benefits

E2000 Automatic Shutter Connector for Enhanced End-Face Protection

One of the defining characteristics of the E2000 connector is its integrated automatic shutter mechanism.

When the connector is unplugged, the shutter automatically covers the ceramic ferrule end face, helping reduce exposure to dust, oil, and airborne contaminants that can affect optical performance.

This design is particularly beneficial in:

• High-density ODF systems
• Central offices and telecom facilities
• FTTH access networks
• CATV headend installations
• Reflection-sensitive optical transmission systems
• Networks requiring frequent maintenance or reconnection

Connector contamination remains one of the most common causes of increased insertion loss, degraded return loss, and service interruptions. By helping protect the ferrule surface, the E2000 shutter mechanism contributes to improved connection stability and reduced maintenance requirements.

Note: Specific shutter construction details and connector specifications should be verified against the manufacturer's technical documentation.

APC 8° Angled Polish for Low-Reflection Optical Links

The pigtail utilizes an APC (Angled Physical Contact) polished ferrule featuring an 8-degree angled end face.

Unlike UPC connectors, APC polishing redirects reflected optical signals away from the fiber core, helping minimize the impact of back reflection on sensitive transmission systems.

APC connectivity is commonly deployed in:

• GPON networks
• XGS-PON infrastructure
• CATV optical transmission systems
• DWDM and CWDM networks
• Long-haul singlemode links
• High-power optical systems
• Telecom access and transport networks

For networks where return loss is a critical consideration, APC connectors are widely preferred to support stable optical performance and signal integrity.

Actual insertion loss and return loss values should be confirmed through factory test reports and product specifications.

G657.A2 Bend-Insensitive Fiber for FTTH and High-Density Cabling

This pigtail is manufactured using G657.A2 bend-insensitive singlemode fiber.

Compared with conventional singlemode fiber, G657.A2 is designed to maintain optical performance more effectively in installations involving tighter bend radii and limited routing space.

Typical benefits include:

• Suitable for FTTH drop connections
• Improved flexibility in fiber distribution boxes
• Reduced risk of bend-induced attenuation
• Easier routing within crowded telecom cabinets
• Better cable management in high-density environments

Typical deployment scenarios include:

• FTTH subscriber connections
• Fiber distribution hubs
• Building backbone cabling
• Telecom access networks
• Indoor optical routing systems

Simplex Construction for Single Fiber Termination

The simplex design contains a single optical fiber and is commonly used for one-way optical connections, fiber splicing projects, and network terminations.

Typical applications include:

• Fiber cable termination
• ODF integration
• Fiber terminal boxes
• FTTH distribution points
• Telecom equipment connections

Its straightforward construction simplifies installation and fiber management.

LSZH Jacket for Safer Indoor Installations

The cable utilizes an LSZH (Low Smoke Zero Halogen) outer jacket designed for indoor applications where fire safety and reduced smoke generation are important considerations.

Typical installation environments include:

• Telecommunications rooms
• Data centers
• Enterprise buildings
• FTTH indoor routing
• Public infrastructure facilities
• High-density fiber distribution systems

In the event of fire, LSZH materials typically produce lower levels of smoke and corrosive gases than conventional PVC jackets, helping improve safety for personnel and equipment.

The yellow outer jacket follows industry conventions for identifying singlemode fiber connections, simplifying installation, maintenance, and troubleshooting.
