Fiber optic cables with fiber optic connectors (such as LC, SC, ST, MU, or MPO/MTP) at both ends are called fiber optic patch cords. Fiber optic patch cords are one of the most widely used fundamental components in optical communication, primarily used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission networks, and local area networks (LANs). Fiber optic patch cord can also be used in cable television networks, communication networks, computer fiber optic networks, and fiber optic testing equipment.
Fiber optic patch cords come in various types according to different standards. They can be classified based on key parameters, including connector type, fiber mode, fiber count, jacket material, and end-face polishing. Understanding these specifications is crucial for selecting the right fiber optic patch cord to meet network performance, transmission distance, and environmental requirements.
The following is a brief overview of the mainstream fiber optic patch cord types.
Fiber optic patch cords can be classified according to the type of fiber optic connector. The most common and mainstream types include SC, LC, FC, and ST fiber optic patch cords, as well as MPO/MTP, Unoboot LC, MDC, MU, MT-RJ, and E2000 fiber optic patch cords.
Although these different types of fiber optical patch cords have similar components (composed of fiber optic connectors and optical cables) and the same functions, their application scenarios differ due to the different characteristics and performance of the optical connectors.
According to fiber types, optical fiber patch cables are classified into singlemode and multimode fiber optic patch cord.
Singlemode fiber optic patch cord usually comes with a yellow outer sheath. They feature a 9/125um core, low dispersion, and support only one transmission mode, which brings low signal loss and makes them ideal for long-haul communication. As a professional manufacturer of fiber optic patch cords, UnitekFiber provdes a wide range of singlemode options, including G652D, G657A1/A2/B1/B2/B3, and Corning SMF-28 Ultra.
Multimode fiber features a 62.5/125um(OM1) or 50/125um(OM2/OM3/OM4/OM5) cores, relatively high dispersion, and exceptional bandwidth capacity, supporting hundreds of transmission modes. These characteristics make multimode fiber patch cords extremely popular for short reach data transmission applications.
Multimode fiber patch cords are easily identified by their jacket colors, like OM1 and OM2 is orange, OM3 is aqua, OM4 is violet, and OM5 is lime green.
In terms of transmission performance:
OM1 fiber patch cords support 10G transmission up to 33 meters.
OM2 fiber patch cords extend 10G reach to 82 meters.
OM3 fiber patch cords achieve 10G up to 300 meters and 100G up to 75 meters.
OM4 cable enables laser optimized transmission over 150 meters, supports 10Gb up to 550 meters, and maintains 100Gb transmission up to 100 meters for high bandwidth deployments.
Fiber optic patch cables can be divided into simplex and duplex types based on their interface transmission structure.
Simplex fiber patchcord ontains a single fiber strand, and only allows data to be transmitted in one direction, which is irreversible. Usually, using with BiDi (bidirectional) transceivers that send and receive signals over the same fiber.
Duplex fiber patch cables are constructed with two separate fiber cores and dual connectors at both ends, enabling simultaneous data transmission and reception. This type is widely applied for linking high speed network devices, including servers and fiber optic network switches.
The polishing type of fiber optic connectors significantly affects return loss and signal performance:
UPC (Ultra-Physical Contact): Features low insertion loss and moderate return loss, suitable for most Ethernet, telecommunications, and general data transmission applications.
APC (Angled Physical Contact): The APC end face is angled at 8°, minimizing back reflections, making it ideal for FTTH, RF video, and PON systems with extremely high precision and low reflection requirements.
PC (Physical Contact): Due to its lower performance, this older design has now been largely replaced by UPC and APC.
For applications requiring minimal signal reflection and high precision, APC connectors are the preferred choice. For cost effective, general purpose deployments, UPC connectors offer reliable performance.
There are different jackets for fiber optic patch cords, including PVC, LSZH, ofnr OFNP, etc.
Fiber patch cord with PVC jacket is a popular choice for general cabling systems due to their cost effectiveness and versatility. LSZH fiber optic patch cord emits minimal smoke and no halogen gases, making them highly suitable for enclosed public areas including offices, hospitals, and other spaces with strict safety requirements. OFNR fiber optic patch cord is designed for vertical riser shafts between floors. OFNP fiber optic patch cord offers the highest fire-resistance grade, required for air-handling spaces like ceilings, ducts, and ventilation systems.
UnitekFiber has obtained ROHS, UL, and CPR certifications to ensure that our fiber optical patchcords meet your requirements. And choose the right jacket based on building fire codes and installation conditions to ensure both safety and compliance.
Micro-armored Fiber Optic Patchcord
Meanwhile, the micro-armored fiber optic patchcord feature stainless steel or Kevlar reinforcement inside the jacket, protecting against crushing, bending, and rodents. Ideal for factory floors, data centers, or harsh environments.
Mode conditioning fiber optic patchcord are designed to support the use of singlemode optics in multimode fiber systems. By integrating a short length of singlemode fiber within a duplex multimode jumper, mode conditioning fiber patchcord align the laser signal to minimize differential mode delay (DMD), which causes modal dispersion.
Different network infrastructures have unique requirements for cable specifications and connector setups. It is critical to identify the interface type of the connected equipment to select the appropriate fiber connector, such as LC, SC, FC, ST. In addition, the fiber end-face polish profile must also be carefully chosen.
Selecting fiber patch cords according to transmission speed and link distance is critical for maintaining strong signal quality, minimizing data errors, and reducing excessive signal attenuation over long-haul connections.
Singlemode fiber excels in long distance(typically used for links 500m to several kilometers) , high bandwidth transmission. In contrast, multimode fiber performs best over shorter ranges, generally no more than 500m, for applications with standard bandwidth requirements.
Higher data rates such as 100 Gbps demand higher performance cabling solutions, including OM4/OM5 multimode or singlemode fiber, to effectively control dispersion and guarantee error-free data delivery.
Data centers, in particular, require forward looking infrastructure design, where cable bandwidth capacity plays a key role. As an example, the growing adoption of OM5 fiber over OM3/OM4 in newly built data centers shows the industry’s preparation for surging traffic driven by VR, AR and AI applications.
It’s important to evaluate the operating environment where the fiber patch cord will be installed. The outer jacket material must be durable enough to resist factors including temperature fluctuations, moisture, and physical wear.
Typical jacket options for fiber optic patch cords include PVC, LSZH, and OFNP. PVC is widely used for standard indoor applications. LSZH is preferred in environments requiring low smoke and zero halogen emissions, such as data centers. OFNP is specially designed for plenum areas with strict fire safety regulations, commonly found in commercial buildings.
When selecting between simplex and duplex fiber patch cables, you should base your decision on your actual communication requirements. A simplex cable is sufficient for oneway data transmission. For bidirectional communication systems like networks and telecom equipment, duplex cables are the more suitable option.
In addition, you must choose the proper cable length according to the actual distance between connected devices. Using excessively long cables can increase signal loss and attenuation, so accurate length selection helps maintain stable transmission performance.
When selecting fiber optic patch cords, it is critical to source from reliable manufacturers with a proven track record of high quality production.
