What Are indoor Fiber Optic patch cables Types?


Cable Types

Indoor patch cord is current normal one. it is used to attach one device to another for signal routing.



Data transmission.


Testing equipment.


Optical fiber CATV,

LAN indoor/outdoor.


PC UPC APC polishing optional

High credibility and stability

Low insertion loss, high return loss

400X microscope inspecting.

Good in repeatability and exchangeability

Singlemode or Multimode fiber optional

1. Single mode fiber patch cables:  Single mode fiber optic patch cables use 9/125 micron bulk single mode fiber cable and single mode fiber optic connectors at both ends. Single mode fiber optic cable jacket color is usually yellow. Here is the explanation of what is single mode and single mode fiber.

2. Multimode fiber patch cables: Multimode fiber optic patch cables use 62.5/125 micron or 50/125 micron bulk multimode fiber cable and terminated with multimode fiber optic connectors at both ends.  Multimode fiber optic cable jacket color is usually orange. Here is the explanation of what is multimode and multimode fiber.

3. 10gig multimode fiber optic patch cables:  10Gig multimode fibers are specially designed 50/125 micron fiber optimized for 850nm VCSEL laser based 10Gig Ethernet. They are backward compatible with existing network equipment and provide close to three times the bandwidth of traditional 62.5/125 multimode fibers. 10 Gigabit is rated for distances up to 300 meters using 850nm Vertical Cavity Surface Emitting Lasers (VCSEL). 10Gig fiber optic cable jacket is usually aqua.

Fiber optic patch Cable Structure:

1. Simplex fiber optic patch cables: Simplex fiber patch cable has one fiber and one connector on each end.

2. Duplex fiber optic patch cables: Duplex fiber patch cable has two fibers and two connectors on each end. Each fiber is marked “A” or “B” or different colored connector boots are used to mark polarity.

3. Ribbon fan-out cable assembly: For ribbon fan-out cable assembly, one end is ribbon fiber with multi fibers and one ribbon fiber connector such as MTP connector (12 fibers), the other end is multi simplex fiber cables with connectors such as ST, SC, LC, etc.


Simplex vs duplex

Connector design standards include

FC, SC, ST, LC, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, and D4. Cables are classified by the connectors on either end of the cable; some of the most common cable configurations include FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, and SC-ST


Fiber Optic connector Selection Guide



Connector Polishing Types:

Fiber optic connectors are designed and polished to different shapes to minimize back reflection. This is particularly important in single mode applications. Typical back reflection grades are -30dB, -40dB, -50dB and -60dB. Refer to this connector fiber polish types document for more information.

1. PC (Physical Contact): Typical back reflection <-40dB, for single mode and multimode applications.

2. UPC (Ultra Physical Contac t): Typical back reflection <-50dB, for single mode applications.

3. APC (Angled Physical Contact): Typical back reflection <-60dB, for single mode applications.
