A fibre optic pigtail like 12 LC Pigtail functions as a link between two distinct connecting techniques. A factory-installed connector (LC, SC, ST, or FC) is present on one end. The bare fibre on the other end is prepared for mechanical splicing or fusion with your optical connections.
A typical installation problem is resolved
by this design. Without sacrificing the flexibility to splice straight into
your current fibre infrastructure, you may enjoy the dependability of
factory-terminated connectors.
Distinctions
between pigtail and patch chord
These two types of fibre cables are often confused by installers. This is how they are different:
Patch
cord and pigtail
Connectors: Both ends of patch cords are equipped with factory-installed connectors. One connector and one splice-ready end make up a pigtail.
Length: For equipment connections, the majority of patch cords are between one and five meters long. For permanent installations, bunches usually run longer at 10 meters or more.
Application: For transient or interchangeable connections between devices, use patch cords. For long-term splicing into your fibre backbone, opt for bunches.
Installation: Patch cords should be plugged in right away. Fusion splicing, which requires specialised equipment but produces stronger, lower-loss connections, is necessary for pigtails.
Your network design will determine the decision. Pigtails like 12 SC pigtail are preferred for permanent installations due to their dependable splicing. Removable patch cords improve the functionality of patch panels and equipment racks.
Fibre Pigtail Types
Options
for Fibre Mode:
Single-mode (OS2): 9/125µm core for up to 40 km of long-distance transmission
For short distances under two kilometres, the multimode (OM1/OM2/OM3/OM4/OM5) is 50/125µm or 62.5/125µm.
Fibre Count: For high-density installations, single fibre up to 144-count ribbon variants are available.
Types
of Connector Polish:
PC (Physical Contact): Typical polish for simple uses
Improved return loss performance with UPC (Ultra Physical Contact)
APC (Angled Physical Contact) minimises back-reflection and performs best at an 8-degree angle.
Customised
Pigtail Designs
Bundled Pigtails: Several fibres in a single protective sheath with a flame-resistant PVC jacket and aramid strength members. In dense installations, these lessen the complexity of cable management.
Armoured Pigtails: Mechanical stress and rodent damage are prevented by steel or aluminium armour. 12 LC Pigtail vital for installations in tough environments or outdoors.
Waterproof
Pigtails: Direct burial or underwater applications
are handled via gel-filled cables and sealed connectors.
