3 Meter Duplex 62.5/125 (OM1) ST to ST Fiber Jumper Cable
1. Basic Introduction:
Choosing your fiber jumpers is no easy task. The fiber optic jumper cable you pick can affect how quickly data is transmitted from point to point.
Geehe's ST to ST termination, this high-quality fiber optic patch cable is specifically designed for fast ethernet, ATM, and gigabit ethernet applications. The small LC connectors satisfy the need for higher port density both in the telecom room and the work area and offer twice the port density of traditional SC and ST fiber connectors. The LC connector with its RJ-style latch clip design is easy to engage and disengage and gives each connection greater durability in resisting pulls, strains, snags, and impacts during cabling installs and maintenance. The ST connector features a bayonet locking system.

6. Our Service:
Your patch cord selection is important to the type of fiber optic network you are working on. Some are ideal for single-mode, while others might be the right for a Multimode installation. Another factor to consider is the polished type when using single-mode cables.
While your patch cord choice is important, it is only one piece of the fiber-optic network to choose from. Take a look at what's available in these other key product categories:
8. How to choose Fiber patch cords?
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 connect
3) 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.
