How To Choose A Fiber Optic Pigtail Successfully?

Fiber optic patch cables are basic media of optical light transmission. A successful fiber cable choice and deployment is vital for fiber access networks. A well-done cable installation not only makes optical signals pass through the fiber links but also offers low attenuation and little return loss.

This post contains some basic knowledge of fiber optic pigtail, including pigtail connector types, fiber pigtail classifications, and fiber pigtail splicing methods.

How To Choose Correct Fiber Pigtails?

There are different kinds of fiber optic pigtails are available in the market to meet the various applications. The correct choice of fiber pigtails will make our work simple & high efficiency.

By Fiber Type

By fiber types, we could classify fiber pigtails into single-mode fiber pigtails and multimode fiber pigtails. Single-mode fiber pigtails use fiber cables in single-mode 9/125 fiber. By bending radius, single-mode fibers have:

  • G652.D Fiber is highly backward compatible as it has been used in all networks for many years, and their lower attenuation allows for extended network coverage and extra margin to allow future upgrades, and accommodate repairs. However, lacking additional bend resilience, they are also limited to allowing cable and hardware miniaturization and low-cost deployment techniques.
  • Bend Insensitive G657.A1, G657.A2 & G657.B2 Fibers have become popular single-mode fibers in outside plant (OSP) installations in recent years as their bend resistance enables smaller cable designs and low costs installations techniques.
SC OM4 fiber pigtails

SC OM4 fiber pigtails

Multi-mode fiber pigtails are classified as OM1, OM2, OM3, and OM4 types. Each type has different optical properties.

  • OM1 fiber has a core size of 62.5 micrometers (µm). With 200/500 MHz*km overfilled launch (OFL) bandwidth at 850/1300nm, it is commonly used for 100 Megabit Ethernet applications, and it can support 10 Gigabit Ethernet at lengths up 33 meters. The cables in OM1 fiber typically comes with an orange jacket.
  • OM2 fiber has a 50µm core size, and with 200/500 MHz*km overfilled launch (OFL) bandwidth at 850/1300nm. It is more commonly used for 1 Gigabit Ethernet applications, but for 10 Gigabit Ethernet, the maximum transmission distance could reach up to 82 meters. Same as cables in the OM1 fiber, the recommended jacket color is orange too.
  • OM3 fiber has a core size is 50µm, the same as OM2 fiber, but having 2000 MHz*km effective modal bandwidth (EMB, also known as laser bandwidth), 5 times wider than OM2 fiber. As a laser-optimized fiber, it is designed for 10 Gb/s transmissions, running 10 Gigabit Ethernet at lengths up to 300 meters.  Since its inception, production techniques have improved the overall capabilities of OM3 to enable its use with 40 Gigabit and 100 Gigabit Ethernet up to 100 meters.
  • OM4 fiber is a further laser-optimized 50um fiber having 4700 MHz*km EMB bandwidth designed for 10 Gb/s, 40 Gb/s, and 100 Gb/s transmissions. Same as OM2, OM3 fiber, OM4 fiber has a 50um core size, but supports 10 Gigabit Ethernet at lengths up to 550 meters and it supports 100 Gigabit Ethernet at lengths up to 150 meters. The suggested jacket color of fiber cable in OM4 fiber is aqua/rose.

By Connector Type

According to the fiber connectors terminated, The fiber pigtails covers:

  • SC fiber pigtails
  • LC fiber pigtails
  • ST fiber pigtails
  • FC fiber pigtails
  • E2000 fiber pigtails
  • DIN fiber pigtails

Like fiber optic patch cords, The connector of a fiber optic pigtail can be divided into UPC and APC versions, like SC/UPC, SC/APC, LC/UPC. LC/APC, ST/UPC, FC/UPC, FC/APC pigtails, etc.

By Cable Structure

In order to a variety of installation environments, we need to choose pigtails with a specific structure. Based on cable structures, the pigtails could be the following types:

  • Tight Buffer Fiber Pigtails: generally 900um tight buffer fiber cable used, easily stripped PVC or LSZH layer.
  • Multi-Fiber Pigtails: using 2, 4, 6, 8, 12, 24, 48 strand distribution fiber trunk cables, which feature a single jacket containing 2, 4, 6, 8, 12, 24, 48 bare fibers or tight buffer fibers. The outer jacket could be PVC, LSZH, OFNR, or OFNP. By adding breakout kits, the inner fibers could be strengthed up to 2.0mm diameter.

Most fiber pigtails are installed assembled in fiber enclosures, and for indoor use. But a fiber optic pigtail needs to withstand the harsh or extreme environments, so here come armored and waterproof pigtails.

  • Armored Pigtails: constructed with stainless steel tube inside the outer jacket, provide extra protection for the fiber inside and added reliability for the network, while reducing the unnecessary damage caused by rodents, construction work, the weight of other cables.
  • Waterproof Pigtails: designed with a stainless steel strengthened waterproof unit and armored outdoor PE (Poly Ethylene) jacket, featuring good toughness, tensile and reliable performance, suitable for application in harsh environments, like communication towers, CATV, and military.

How To Do Easy & Fast Fiber Pigtail Deployment?

Factory pre-terminated, especially breakout style, fiber pigtail offers stable optical performance, . The open-ended is spliced with the fiber of entrance cables. Given the access to a fusion splicer, you can splice the pigtail right onto the cable in a minute or less, which greatly speeds the splicing and saves significant time and cost spent on field termination. Sometimes, we could use a fast connector on the other end to realize the jump connection as a regular fiber patch cord.
