Overview
The Industrial XGS-PON OLT SFP+ Transceiver (Class N2) is a robust optical module engineered for 10-Gigabit Symmetric Passive Optical Networks (XGS-PON) deployed in harsh environments. Unlike standard commercial modules, this Industrial Temperature (I-Temp) transceiver is rated to operate reliably from -40°C to +85°C, making it the critical component for outdoor street cabinets, unconditioned remote nodes, and mobile backhaul applications.
Adhering to the ITU-T G.9807.1 standard, it provides symmetric 9.953 Gbps bandwidth (both upstream and downstream). It features a Class N2 optical power budget, offering superior link margin compared to Class N1, ensuring stable connectivity over 20km with split ratios up to 1:64.
Key Features
- Industrial Grade: Hardened components support extreme temperatures (-40°C to +85°C).
- Symmetric 10G Speed: 9.953 Gbps Downstream / 9.953 Gbps Upstream.
- Optical Class N2: High power budget (~31dB) for robust link performance.
- Wavelengths:
- Tx (Downstream): 1577nm (EML Laser)
- Rx (Upstream): 1270nm (APD Burst Mode)
- Reach: 20km on Single Mode Fiber (SMF).
- Connector: Simplex SC/UPC.
- Compatibility: Fully compliant with ITU-T G.9807.1 and XGS-PON MSA protocols.
Applications
- Outdoor OLT Deployments: Installed in non-climate-controlled street cabinets (FTTC/FTTN).
- 5G Mobile Backhaul: Provides high-speed, low-latency xHaul connectivity in outdoor cells.
- Industrial Networking: Suitable for factories, mines, or utility networks requiring 10G PON in extreme weather.

Class N1 vs. Class N2
In the XGS-PON standard, optical budget classes are defined as N1 and N2.
- Class N1: Nominal budget of 29dB (similar to GPON Class B+).
- Class N2: Nominal budget of 31dB (similar to GPON Class C+).
This Class N2 module provides a higher optical budget, allowing for longer distances or more insertion loss (e.g., from extra patch panels or 1:64 splitters) compared to N1 modules.
FAQ
1. Why do I need an Industrial Temperature transceiver?
If your OLT equipment is located in an outdoor enclosure, street cabinet, or a facility without active cooling (HVAC), ambient temperatures can drop below freezing in winter or exceed 60°C inside the cabinet in summer. Standard commercial modules (0-70°C) may fail under these conditions. This I-Temp module is tested to survive -40°C to +85°C.
2. Can this module support asymmetric 10G/2.5G (XG-PON)?
This is specifically an XGS-PON module (Symmetric 10G). However, many modern OLT line cards and ONUs allow XGS-PON OLTs to communicate with XG-PON ONUs depending on the specific OLT software configuration. Ideally, it is used for symmetric 10G services.
3. What fiber cable is required?
It requires standard Single Mode Fiber (SMF), typically G.652 or G.657, terminated with an SC/UPC connector.
4. Does it support DDM?
Yes, Digital Diagnostic Monitoring (DDM) is standard, allowing remote monitoring of the laser bias, temperature, and optical power levels.
