ST UPC to ST UPC OS2 Simplex Single-Mode Fiber Patch Cord, LSZH
ST UPC to ST UPC OS2 simplex single-mode fiber patch cord with an LSZH jacket, 1m–10m length options and ≤0.5 dB insertion loss.
ST UPC to ST UPC OS2 Simplex Patch Cord for Matching ST Fiber Ports
This ST UPC to ST UPC OS2 simplex single-mode fiber patch cord connects matching ST/UPC interfaces at both ends. Both endpoints use ST connectors with UPC polish, making it suitable for links where legacy or existing equipment requires ST/UPC at both endpoints. The working configuration uses OS2 9/125μm single-mode fiber, simplex construction, an LSZH jacket, 1m–10m lengths, and ≤0.5 dB insertion loss.
| Connector A | ST UPC | Connector B | ST UPC |
| Fiber Type | OS2 9/125μm Single Mode | Fiber Structure | Simplex |
| Cable Jacket | LSZH | Available Length | 1m – 10m |
| Insertion Loss | ≤0.5dB | Application | FTTH, Telecom Network |
ST/UPC at Both Ends
Both endpoints use ST connectors with UPC polish. The bayonet-style ST interface is commonly encountered in legacy telecom, campus, monitoring and industrial fiber installations.
Same-Connector, Same-Polish Link
Because both ends use the same ST/UPC termination, there is no connector-specific A-to-B direction; the key requirement is matching ST/UPC interfaces at both endpoints.
OS2 Simplex with LSZH Jacket
The working configuration uses OS2 9/125μm single-mode fiber, simplex construction, an LSZH jacket, 1m–10m lengths, and ≤0.5 dB insertion loss.
