Options to join optical fiber

• Detachable connectione.g. connectors

• Quasi-detachable connection e.g. mechanical splice

• Non-detachable connection e.g. fusion splice

Connection technique


Which connection

Choice depending on:• Installation (indoor, outdoor, flexibility)• Standard requirement• Active component• Environment/application (public, private)

Connection technique based on:• Availability of tools• Capability installer• Cost• Cost effectiveness (business case and activity)


Non-detachable connection

Fusion splice

Cleave of both fiber ends

Clamp and core alignment

Glow discharge and lateral movement of the fiber


quasi-detachable connection

Mechanical splice

Cleave of both fiber ends

Slide till contact and clamp

Contact area with Index gel to reduce IL and RL


Connection with to connectors in an adapter

Sleeve

Ferrule

Principal 1-fiber connectionFerrule – Sleeve – Principle


Fiber fixed in the ferrule and guided and aligned in the sleeve



Principal multi fiber connectionFerrule – Pin – Principle

All fibers are fixed in one ferrule and aligned with guide pins.

Ferrule

Fiber

FerrulePin


Ferrule


• Fixing fiber (glue and cured)• Corrosion free and abrasion-resistant material• Guides fiber concentric in sleeve• Tolerances of hole Ø and eccentricity are parameter

for production quality

• Ø 2.5mm or 1.25mm (1 fiber connector)

• Plastic composite(multi fiber connector)



• Sleeve guides and aligns round ferrule• fixing of connector (mechanical locking)• Adaptation in platform/distributor• Key to prevent relative rotation

Adapter (1-fiber)

e.g. E-2000

End face process

• Air gap

• Flat polish

• Convex polish (PC) Physical Contact

• Angled polish (APC)Angled Physical Contact)


4% reflection on each end face results in 0.36 dB of loss

Flat polish – air gap

• Non - butting ferrules• No physical contact

Transmission specifications IL < 1.0 dBRL ~ 15 dB


Radius 10 - 25 mm

Convex polish – physical contact

• Butting ferrules• Spherical physical contact (PC)

Transmission specifications IL < 0.5 dBRL > 20 dB


Angled physical contact (APC) polish

• Butting ferrules• Angled spherical physical contact
