How to install StarTech.com MSA Uncoded SFP Module - 100BASE-ZX

• Power down the network device (switch or router) before installing the SFP module to prevent electrostatic discharge or damage.
• Remove the SFP cage cover or open the SFP slot access panel as required by your device’s user guide.
• Insert the SFP module firmly into the appropriate SFP/SFP+ slot until it seats with a click, ensuring the connector faces the correct orientation.
• Connect the single‑mode fiber optic cable to the SFP module’s fiber interface using the proper connectors (commonly LC duplex); secure the fiber to prevent strain on the connector.
• Reattach any covers, power up the device, and verify a link indication on the port LED or the management interface. If available, enable and review DDM data to confirm healthy optical performance.

Frequently asked questions

• What is 100BASE‑ZX? 100BASE‑ZX is a long‑reach Ethernet standard that enables 100 Mb/s data transmission over single‑mode fiber, typically used for WAN links and campus backbones where distances exceed the limits of copper cabling.
• How far can this SFP module reach? It supports up to 80 km (49.7 miles) on single‑mode fiber, depending on the fiber characteristics and site conditions.
• What does DDM stand for and why is it important? DDM stands for Digital Diagnostics Monitoring. It provides real‑time monitoring of key parameters such as optical power, temperature, and module health, helping technicians quickly identify and address link issues.
• Is this module compatible with all brands? The module is MSA‑compliant and designed to work with 100BASE‑ZX devices. While interoperability is generally strong across vendors, it’s recommended to verify compatibility with your specific switches or routers by checking the vendor’s compatibility matrix or testing in a controlled environment.
• Do I need any configuration after installing the SFP? In most cases, no advanced configuration is required. The module should negotiate the 100 Mb/s link automatically with 100BASE‑ZX devices. If needed, verify interface status in the device’s management interface and monitor DDM readings for ongoing health checks.
