PVC Jacket 9/125 Singlemode Duplex SC-SC Patch Cable Fiber Optic
1. Fiber Patch Cord Basic Introduction:
Fiber optic patch cords are used when it is necessary to connect
multiple devices in a network. Normally, they connect a switch to a
patch panel or panel-to-panel. There is a wide range of fiber patch
cords available.
SC-SC Fiber Optic Patch Cord is available in multimode and
single-mode, duplex and simplex. which is used to connect fiber optic equipment to equipment or patch
panel to equipment. It comprises a patch cable terminated with SC
fiber optic connectors. For the fiber types, both Singlemode and
Multimode are supported. Both simplex and duplex patch cord types
are available

6. How to choose fiber patch cord?
1) Fiber Cable Mode: Single Mode or Multimode
The mode of fiber patch cables indicates how light beams travel
within the fiber. There are two fiber cable modes: single mode and
multimode.
2) Number of Fiber Strands: Simplex or Duplex
According to the number of fiber strands, there are simplex and
duplex fiber patch cord. As shown in Figure 2, simplex fiber patch
cord contains one single strand of fiber with one simplex connector
on each end. It can be linked with a pair of BiDi transceiver
modules featuring with one port. Whereas duplex fiber patch cord
consists of two strands of glass or plastic with one duplex
connector (or considered as two simplex connectors). It is often
linked with common transceivers or dual fiber BiDi transceivers.
3) Choose the Right Cable Jacket Type (PVC/LSZH/OFNP/Armored)
Usually, there are three cable jacket types: Polyvinyl Chloride
(PVC), Low Smoke Zero Halogen (LSZH) and Optical Fiber
Nonconductive Plenum (OFNP). You can see there features in figure
below and choose the right one for your network.
4)Connector Type: LC, SC, ST or Others
SC - a snap-in style connector. Known for its excellent
performance. Referred to as Subscriber Connectors, Square
Connectors, or Standard Connectors.
ST - a very popular choice connector for Multimode networks. Also
referred to as Straight Tip connectors, they utilize a
bayonet-style coupling type, enabling a simple twist-on and
twist-off installation.
FC - was at one time the most popular single-mode connector type,
but is now typically being replaced by SC and LC connectors. Also
known as Ferrule Connectors, they utilize a screw-on coupling type
to be used in high-vibration environments and are commonly used for
datacom, telecom, measurement equipment, and single-mode lasers.
LC - a small form factor connector—measuring half the size of an SC
connector. This is a popular choice for single-mode cables. Also
referred to as Lucent Connectors, Little Connectors, or Local
Connectors, these snap-in connectors are typically used for
high-density connections and are compatible with plug-and-play
devices such as SFP modules and XFP transceivers.
5) Choose the Right Connector Polish Type (UPC/APC)
Since the loss of the APC connector is lower than UPC connectors,
usually, the optical performance of APC connectors is better than
UPC connectors. In the current market, the APC connectors are
widely used in applications such as FTTx, passive optical network
(PON) and wavelength-division multiplexing (WDM) that are more
sensitive to return loss. But APC connector is usually expensive
than UPC connector, so you should weigh the pros and cons. With
those applications that call for high precision optical fiber
signaling, APC should be the first consideration, but less
sensitive digital systems will perform equally well using UPC.
Usually, connector color of APC patch cable is green, and of UPC
patch cable is blue.
