Overview
The Industrial Temperature XGS-PON & GPON Combo OLT SFP+ Transceiver is a ruggedized optical module designed for harsh environments and outdoor deployments. As a Class B+ Multi-Protocol Module (MPM), it enables the simultaneous transmission of 10G XGS-PON and 2.5G GPON services over a single fiber infrastructure.
Engineered with hardened components, this module operates reliably in extreme temperatures ranging from -40°C to +85°C. It is the perfect solution for Service Providers deploying OLT equipment in non-climate-controlled street cabinets, remote nodes, or industrial sites.
Key Features
- Dual-Mode Operation: Integrated XGS-PON and GPON MAC support in one SFP+ module.
- Industrial Temperature (I-Temp): Certified for operation from -40°C to +85°C.
- Optical Class B+: Optimized optical power budget for standard network architectures (typically 1:64 split ratio).
- Wavelengths:
- XGS-PON: 1577nm (Tx) / 1270nm (Rx)
- GPON: 1490nm (Tx) / 1310nm (Rx)
- Reach: Up to 20km over Single Mode Fiber (SMF).
- Connector: Simplex SC/UPC interface.
Applications
- Outdoor Street Cabinets: Ideal for Remote OLTs positioned in roadside cabinets where temperatures fluctuate drastically.
- Rural Broadband Expansion: Reliable connectivity for remote nodes lacking stable environmental controls.
- Cost-Effective Upgrades: Allows operators to introduce 10G services on existing Class B+ ODN networks without replacing optical splitters.

Why Choose Class B+ I-Temp?
While Class C+ modules offer higher power, Class B+ modules provide a cost-efficient solution for networks with standard split ratios (1:64) and moderate distances. Combined with Industrial Temperature tolerance, this transceiver ensures zero downtime during freezing winters or scorching summers, protecting your network’s reputation for reliability.
FAQ
1. What does “Class B+” mean in this context?
Class B+ refers to the optical power budget of the transceiver. It typically offers a budget of around 28dB, which is sufficient for standard PON networks with a 1:64 split ratio and distances up to 20km. It has slightly lower transmit power compared to Class C+.
2. Can I use this I-Temp module in a normal server room?
Yes, you can. Industrial Temperature modules exceed the requirements of commercial environments. However, they are typically more expensive than commercial (C-Temp) versions, so they are best justified when environmental conditions (heat or cold) are a concern.
3. How does the Combo feature work?
The module contains two lasers and two detectors. It transmits GPON data at 1490nm and XGS-PON data at 1577nm simultaneously. Compatible ONUs (modems) at the customer end will filter and receive only the signal meant for them, allowing both legacy and new users to share the same fiber.
4. Does this module support DDM?
Yes, it supports Digital Diagnostic Monitoring (DDM), allowing network administrators to monitor critical parameters like temperature, voltage, laser bias current, and optical power levels in real-time.
