3M ST/SC Duplex Multimode 50/125 OM2 3.0mm Fiber Patch Cable, Orange
1. Basic Introduction:
50/125 OM2 Multimode fiber is crafted and created for fast Ethernet, Fiber Channel, Gigabit Ethernet Speeds, data center, OM2 legacy, Local Area Networks, SAN, backbone, riser, and horizontal applications.
OM2 fiber patch cords operate at a recommended spectrum of temperature: (-4°F to +158°F) and have a MIN Install Bend radius of 5.00 cm and a MIN long-term Bend radius of 3.00 cm.
OM2 50/125 Multimode fiber patch cords reduce the installation process and minimize the total cost of installation, due to pre-terminated fiber intrinsic plug-and-play feature.
ST connector has a Twist-on / twist off bayonet mount with a ceramic ferrule.
2. ST to SC Patch Cord Benefit & Features:

6. 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 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) 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.
