SC to ST Duplex Multi Mode OM1 PVC 2.0mm Fiber Optic Patch Cable

1. Basic Introduction:

Multimode patch cable uses 62.5/125µm fiber optic cable with dual SC connectors on one end and dual ST connectors on the other. SC are square push-pull connectors and utilized with devices such as fiber patch panels, media converters, etc. ST connectors have metal barrels that twist on or of an ST receptacle, also known as a “bayonet.”

The polish type is PC (Physical Contact) for excellent contact and performance.

2. Patch Cord Benefit & Features:

• Attenuation loss meets or exceeds the latest industry standards
• Simplex, duplex or multi-fiber assemblies
• High precision zirconia ceramic ferrule protected by dust cap
• Low insertion loss, high repeatability, and stability
• Premium connector with ORL ≥ 55dB for UPC and 65dB for APC

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.
