Types of Indoor-Duplex-Fiber-Optic-Cables

Indoor-duplex-fiber-optic-cables are a type of fiber cable used to transmit data between devices. They differ from simplex cables because they have two strands of fiber rather than one. This means that they are capable of bidirectional transmission.

We carry a variety of single mode and multimode duplex fiber cables in various colors, lengths, and constructions including plenum and riser rated. These cables can be terminated with ST or SC connectors.


Duplex fiber optic cables are used for two-way transmissions within devices; one channel sends data while the other receives it. They’re primarily used for networking and backbone applications.

This LSZH OM1 Duplex Single Mode Fiber Cable is made from genuine Corning glass and has a plenum rated construction. A tight buffer, aramid yarn and PVC outer jacket encase the fiber strands, with all materials meeting EU RoHS and REACH Directive standards. This cable is available in 12 TIA standard colors as well as special order colors, and has sequential footage markings on its jacket for easy tracking.


Lc to St Fiber Patch Cable, also known as a multimode OM2 indoor-fiber-optic-patch-cords duplex, is a two-stranded optical fiber cable that uses one sender and one receiver. It is designed to transmit data over shorter distances. These cables are commonly used for Gigabit Ethernet.

These cables have a core diameter of 50 microns and are wrapped in an outer cladding of 125 microns. The difference in core and cladding diameter allows more light to pass through the cable, which minimizes attenuation.

UL Listed OFNP, these cables are ideal for use in plenum and riser spaces. They come with standard surface print denoting construction, NEC rating and fiber type.


When choosing a multimode fiber optic cable, three main factors are important: bandwidth, cable length, and cost. If you have a longer run and very high bandwidth requirements, OM4 is the best option.

OM4 multimode fibers have 50-micron cores and are identified by an aqua jacket. They have a wider range of wavelengths than other multimode fibers and can support 10 Gigabit Ethernet at distances up to 550 meters.

Unlike OM1, OM4 is reverse-compatible with OM3, so it can be used in systems that use OM3. However, the biggest difference between the two is their modal bandwidth. OM4 has a higher modal bandwidth (4700 MHz*km) than OM3, so it can carry more data over a longer distance.


OM4 fiber is laser-optimized with a 50/125um core and meets the ISO 11801 standard. It’s typically used in data center applications and provides higher speeds than OM3. The improved attenuation and dispersion parameters of OM4 enable longer distances between connections.

These cables are suitable for backbone cabling between telecommunications rooms or within the data center between main networking switches. They’re also often used as patch cords for routing connections between electronic equipment and data centers. This plenum-rated fiber cable features a tight buffer, aramid yarn and PVC outer jacket that meets the EU RoHS and REACH directive standards. It includes surface print denoting construction, NEC rating and fiber type as well as sequential footage markings.


OM5 is the latest development in multimode fiber systems, and it offers performance that meets increasing data center demands without requiring new infrastructure. It supports longer transmission distances than older technologies, and it’s backward compatible with OM3 and OM4 systems.

This duplex fiber cable uses two simplex units held together in a tight buffer design. It’s commonly used for LAN connections and patch cords, and it features Low Smoke Zero Halogen (LSZH) or PVC jacketing.

This cable is plenum rated and made with Corning glass. A tight buffer, aramid yarn, and PVC outer jacket encase the optical fiber strands inside; the overall construction meets EU RoHS standards. It also has sequential footage markings to help you keep track of your installation.


CommScope offers a wide variety of indoor fiber optic cables. These optical cables work seamlessly in buildings to provide reliable connections. They use a central tube design to support easy installation. They have low tensile strength and are lightweight.

Our OM2 50/125 Multimode Duplex Fiber Cable with Corning optical fiber is available in several lengths. It features a black polyethylene outer jacket to protect against moisture and sunlight exposure. The tightly buffered PE layer also protects the orange colored, OFNR riser rated PVC inner jacket that’s UV resistant and flame-retardant.

This singlemode 9/125 plenum fiber assembly is resilient and flexible for jumpers, patch cords, and optical-fiber-rangers-otdr pigtails. It’s constructed with a tight buffer, aramid yarn, and PVC outer jacket that meets EU RoHS and REACH Directive standards.


Commscope offers an optimized fiber cable solution for all your indoor applications. We carry all types of single-mode and multi-mode cables in various constructions, with premium connectors that ensure long-lasting durability.

This OM4 Duplex Fiber Patch Cable, also known as zip cord or jumper, features Corning optical glass. It’s OFNP rated and suitable for 10 gigabyte data applications.

Unlike simplex cables, duplex cables feature two strands of fiber that can send and receive data simultaneously. This makes them a better choice for high-speed data transmission. They also have a central tube design, reducing the likelihood of failure due to bends.


Often referred to as “patch cords” or “pigtails,” these short cables connect indoor instruments and communications equipment. They are used to route connections in patching systems and link devices to main fiber optic cables.

Compared to simplex cables, which contain one optical fiber, duplex cable contains two strands of fiber and is capable of sending and receiving data at the same time. They are ideal for applications requiring simultaneous bidirectional communication between devices.

This OM4 single mode duplex fiber optic cable has a plenum rated jacket for use in ducts and air-handling spaces. It is manufactured with genuine Corning glass and meets UL LSZH and RoHS standards.


Unlike simplex fiber cables, which only have one fiber, duplex fiber cables have two strands of optical fiber in the same outer jacket. This allows for simultaneous, bidirectional data transfer. They’re typically used for applications where a separate transmit and receive connection is necessary.

This particular OM4 plenum cable has a tight buffer, aramid yarn, and PVC outer jacket encasing the two optical fibers within. The materials in this cable meet EU RoHS and REACH Directive standards. It comes in 12 TIA standard colors and can also be made to order with special-order color options. It is UL Listed OFNP for use in environmental air handling spaces like ducts and plenums.
