Q1: What pairing is required for the Extreme 10GB-BX20-D? A: The 10GB-BX20-D (Downstream) transmits at 1330nm and receives at 1270nm. For a functional link, it must be paired with the 10GB-BX20-U (Upstream) module, which uses 1270nm-TX and 1330nm-RX.
Q2: Will this module work with ExtremeXOS (EXOS) without port errors? A: Yes. HYTOPTODEVICE modules are pre-programmed with Extreme-specific signatures. Your switch will recognize it as a native 10GB-BX20-D, ensuring plug-and-play performance without needing "unsupported transceiver" overrides.
Q3: Does it support real-time monitoring on VSP/VOSS switches? A: Absolutely. It supports full Digital Optical Monitoring (DOM/DDM). You can use the CLI commands to monitor real-time temperature, TX/RX power, and voltage, which is essential for maintaining a healthy 20km optical link.
Q4: Can I use this 20km module for a 2km link? A: Yes. The high-quality laser in our 10G SFP+ 20km BiDi features a wide dynamic range, allowing it to function perfectly on shorter spans without saturating the optical receiver.
Q5: Is it hot-swappable in a running Extreme switch? A: Yes. The module is hot-pluggable, allowing you to insert or remove the transceiver while the switch is powered on without disrupting other network traff
