High Return 0.9mm Riser Rated (OFNR) 2M Duplex SC To ST Multimode
Fiber Patch Cord
1.Basic Introduction:
SC to ST Fiber Optic Connector is a snap-in connector fiber also
with a 2.5 mm ferrule that is widely used for it Is excellent
performance. It Is a snap-in connector that latches with a simple
push-pull motion. It is also available in a duplex configuration,
the durable rubber boots protect against damage typical in busy
data racks and each end is properly labeled for easy
identification.
The cable has ST to SC connectors, a PVC jacket, and is FDDI and
OFNR rated. Duplex multimode fiber is most commonly used in LAN
applications.
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
- Operating temperature in compliance with IEC 61753-1

7. 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.
