1. What is the difference between VSOL GPON and XGS-PON?

GPON (Gigabit Passive Optical Network) supports downstream speeds up to 2.5Gbps and upstream speeds up to 1.25Gbps. XGS-PON (10-Gigabit-capable Symmetrical PON) offers symmetrical 10Gbps speeds in both directions, making it ideal for high-bandwidth applications and enterprise use.

2. How do I log in to a VSOL GPON or XGS-PON OLT?

Connect your PC to the management port of the OLT. Use the default IP address (commonly 192.168.8.200 for GPON). Access via web browser or Telnet (using credentials such as admin/Xpon@Olt9417# for initial setup). Change these defaults after the first login for security.

3. How many ONTs can be connected per OLT port?

For VSOL GPON OLT ports, the maximum optical splitting ratio is typically 1:128 (up to 128 ONTs per port). For XGS-PON, the ratio can be up to 1:256, supporting a larger number of users per port.

4. Are VSOL OLTs compatible with ONTs from other brands?

Most GPON and XGS-PON OLTs and ONTs are interoperable if they follow international standards (ITU-T), but optimum performance and management are achieved with devices from the same brand. Always check for compatibility.

5. How do I configure VLANs and profiles on VSOL OLTs?

Create VLANs and then assign line and service profiles to PON interfaces from the web GUI or CLI. Assign ONTs to corresponding VLANs for different services (internet, voice, video).

6. What is the maximum distance between a VSOL GPON OLT and ONU/ONT

The maximum distance between a VSOL GPON OLT and an ONU/ONT is typically up to 20 km, following the GPON standard (ITU-T G.984). This distance can vary depending on the split ratio, fiber quality, and optical power budget. For most deployments, staying within 20 km ensures reliable and predictable performance.

7. What is the warranty on my VSOL device?

MiRO provides a standard 1-year warranty on all VSOL devices, valid from the date of purchase.

8. Does VSOL support centralized management of OLTs?

Yes, VSOL offers centralized management through its INCE Cloud platform. This comprehensive cloud-based solution allows you to monitor, configure, and troubleshoot all your VSOL OLTs and other network devices from a single interface. It supports remote firmware upgrades, performance analytics, alarm notifications, and user access control, making it ideal for efficient network administration and scalable deployments.
