1.Ko nozīmē optiskās šķiedras bize?
A fiber optic pigtail works like a bridge between two different connection methods. One end features a factory-installed connector (LC, SC, ST, or FC). The other end has bare fiber ready for fusion or mechanical splicing to your optiskie kabeļi.
This design solves a common installation challenge. You get the reliability of factory-terminated connectors without losing the flexibility to splice directly into your existing fiber infrastructure.
The result is faster installations with fewer connection points that could fail.
You’ll find pigtails installed in optical distribution frames (ODF), šķiedru spaiļu kārbas, and distribution panels throughout data centers and telecommunications networks.
2.Atšķirības starp plākstera auklu un bizi
Many installers confuse these two fiber cable types. Here’s how they differ:
Savienotāji: Patch cords have factory-installed connectors on both ends. Pigtails have one connector and one splice-ready end.
Garums: Most patch cords measure 1-5 meters for equipment connections. Pigtails typically run longer at 10+ meters for permanent installations.
Pieteikums: Use patch cords for temporary or changeable connections between devices. Choose pigtails for permanent splicing into your fiber backbone.
Uzstādīšana: Patch cords plug in immediately. Pigtails require fusion splicing, which takes specialized equipment but creates stronger, lower-loss connections.
The choice depends on your network design. Permanent installations favor pigtails for their splice reliability. Equipment racks and patch panels work better with removable patch cords.
3. Šķiedru pigtailu veidi
Standard Classifications
Fiber Mode Options:
- Vienrežīms (OS2): 9/125µm core for long-distance transmission up to 40km
- Daudzrežīms (OM1/OM2/OM3/OM4/OM5): 50/125µm or 62.5/125µm for short distances under 2km
Šķiedru skaits: Available from single fiber up to 144-count ribbon configurations for high-density installations.
Connector Polish Types:
- PC (Fiziskais kontakts): Standard polish for basic applications
- UPC (Ultra fiziskais kontakts): Better return loss performance
- APC (Leņķiskais fiziskais kontakts): Best performance with 8-degree angle, reduces back-reflection
Specialized Pigtail Designs
Bundled Pigtails: Multiple fibers in one protective sheath with aramid strength members and flame-retardant PVC jacket. These reduce cable management complexity in dense installations.
Bruņotie pigtails: Steel or aluminum armor protects against rodent damage and mechanical stress. Essential for outdoor or harsh environment installations.
Ūdensizturīgi pigtails: Sealed connectors and gel-filled cables handle direct burial or underwater applications. Meet IP68 ratings for complete submersion.
4.Kā izvēlēties pigtails?
Galvenie šķiedru veidi optisko šķiedru bizēs ir daudzmodu (OM1/OM2/OM3/OM4/OM5) un vienmodu (G652D/G657A).
Ietver arī parasto optisko šķiedru bizes savienotāju veidus SC, ST, FC, LC un E2000.
Praktiskiem lietojumiem nav noteiktas izvēles, un jums būs jāizvēlas atbilstoši faktiskajam lietojumam. Kā mūsu tīklam izvēlēties pareizo bizi? Vienkārši izpildiet šos 5 soļi.
Solis 1:Izvēlieties pareizo savienotāja veidu (LC/SC/ST/FC/E2000)
Check your equipment specifications first. Different devices require specific connectors:
E2000: European installations, high-performance applications
LC: High-density applications, modern transceivers
SC: Older equipment, some telecommunications gear
ST: Legacy installations, some security systems
FC: Precision instruments, pārbaudes iekārtas
Solis 2:Select Fiber Type
Vienrežīms (Yellow Jacket): Choose for distances over 2km or high-bandwidth applications. Uses 9/125µm fiber with laser light sources.
Daudzrežīms (Orange Jacket): Pick for short distances under 2km with LED or VCSEL light sources. Available in 50/125µm (preferred) or 62.5/125µm (legacy).
Match your existing cable type to avoid costly converters or adapters.
Solis 3:Izvēlieties pareizo bizes garumu
Measure the actual distance from your splice point to the equipment connection.
Add 20% for routing flexibility and strain relief. Standard lengths include 0.5m, 1m, 1.5m, and 2m for most applications.
Longer pigtails cost more and create cable management challenges. Shorter ones may not reach properly.
Solis 4:Pareiza savienotāja pulēšanas veida izvēle (UPC / APC)
UPC (Blue Boot): Standard choice for most applications. Provides -50dB return loss, suitable for data networks and basic telecommunications.
APC (Green Boot): Required for high-performance applications like FTTH, PON networks, and DWDM systems. Delivers -60dB return loss but costs 15-20% more.
Never mix UPC and APC connectors in the same link. They’re not compatible and will damage each other.
Solis 5:Pareiza jakas materiāla izvēle (PVC / LSZH )
PVC: Lower cost option for indoor installations. Adequate flame resistance for most building codes.
LSZH (Zems dūmu nulles halogēns): Required for plenum spaces and many European installations. Costs 10-15% more but meets stricter fire safety requirements.
Check your local building codes before ordering. Some jurisdictions mandate LSZH for all indoor fiber installations.
Installation Best Practices
Clean all connectors before mating to prevent contamination damage. Store spare pigtails in protective caps to maintain end-face quality.
Plan your splice points carefully since pigtail placement affects future maintenance access.
Quality pigtails reduce network downtime and maintenance costs. Choose suppliers who provide insertion loss and return loss test data with each product.
