7m Fiber Optic Cable - Multimode Duplex 62.5/125 LSZH Fiber Jumper Cord - LC/ST

Questions & Answers

Everything is hooked up but nothing is working. What should I do?
When you troubleshoot issues with a network cable, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue: Network devices Network cables To test your setup components, try the following: Use the network devices and network cables in another setup to see if the problem is with the components or the setup. Use different network devices and network cables in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup. When you test your cables, it is recommended that you do the following: Test each cable individually. Use short cables when you are testing. When you test the network devices and network cables, make sure that the link LEDs (if present) turn on for both of the devices. This indicates basic network connectivity between the network devices. You also need to determine if your devices need a straight through or a crossover cable. For more information about straight through and crossover cables, see the following FAQ: http://www.startech.com/faq/network_cables_straight_through_vs_crossover If the link LEDs are not illuminated or there are not any LEDs present, you will need to troubleshoot your devices. Alternatively, you can also use a network cable tester, such as the REMOTETEST or LANTESTPRO .

How do I choose a compatible fiber cable for this fiber media converter?
The fiber cable must match the media converter’s mode, wavelength, connector type, and transmission requirements. Explanation: Fiber cable compatibility with this fiber media converter depends on matching key specifications: Mode compatibility: The cable must match the supported fiber mode (single-mode or multi-mode). Wavelength compatibility: The cable must support the same operating wavelength as the media converter (for example, 850 nm, 1310 nm, or 1550 nm). Wavelength cannot be changed by the cable. Connector compatibility: The cable connectors (such as LC, SC, ST, or MT) must match the media converter ports. Simplex vs. duplex: Both simplex (separate transmit and receive connectors) and duplex (paired transmit and receive connectors) cables are supported, provided they match the port configuration. Cable classification and performance: Fiber type (for example, OM1–OM5 for multi-mode) must meet the required distance and bandwidth, even though basic compatibility depends on matching the mode. When using fiber media converters to extend a copper Ethernet network, both ends of the fiber link must use the same fiber mode, wavelength, and standard to ensure proper communication.

What is the difference between UPC and APC fiber connectors, and which type do StarTech.com fiber products use?
UPC and APC connectors differ in their end-face polish, and StarTech.com fiber products use UPC connectors. Explanation: UPC (Ultra Physical Contact) and APC (Angled Physical Contact) are fiber connector types that differ in how the fiber end face is polished: UPC connectors: The fiber end face is polished flat with a slight dome shape to ensure direct core contact and low insertion loss. APC connectors: The fiber end face is polished at an 8-degree angle to reduce back reflection in high-performance applications. UPC and APC connectors are not compatible and should not be mated. The angled surface of an APC connector prevents proper alignment with a UPC connector, which can result in high signal loss or a failed connection. StarTech.com fiber products use UPC connectors, so they must be connected to other UPC-compatible fiber interfaces to ensure proper operation.
