Overview
The XGS-PON & GPON Combo OLT SFP+ Transceiver is a dual-mode optical module designed to streamline the migration from Gigabit PON to 10-Gigabit PON. This Multi-Protocol Module (MPM) integrates both XGS-PON (10G) and GPON (2.5G) functionalities into a single SFP+ interface, allowing Service Providers to deliver mixed services over the same existing Passive Optical Network (ODN) infrastructure.
This version is rated for Commercial Temperature (0°C to 70°C), making it the ideal cost-effective choice for temperature-controlled environments such as Central Offices (CO) and indoor data centers. With a Class C+ optical power budget, it supports split ratios up to 1:128 and distances up to 20km.
Key Features
- Hybrid Technology: Simultanous transmission of XGS-PON and GPON signals.
- Form Factor: Standard SFP+ package.
- High Budget Class C+: Guaranteed high transmit power and receiver sensitivity for complex splitters.
- Wavelengths:
- XGS-PON: 1577nm (Tx) / 1270nm (Rx)
- GPON: 1490nm (Tx) / 1310nm (Rx)
- Reach: 20km over Single Mode Fiber (SMF).
- Connector: Single SC/UPC receptacle.
- Temperature: Commercial (0°C to 70°C).
Applications
- Central Office (CO) Upgrades: Directly plug into OLT chassis in climate-controlled server rooms to upgrade capacity.
- FTTH Evolution: Seamlessly introduce 10G broadband packages to premium customers without disconnecting existing GPON users.
- High-Density Deployments: Reduces rack space usage by eliminating external WDM1r combiners.

Benefits of Commercial Temp MPM
For deployments located inside standard telecom exchanges or data centers where air conditioning maintains a stable environment, this Commercial Temperature module offers the same high performance as industrial versions but at a more attractive price point. It allows operators to maximize ROI while future-proofing their access network.
FAQ
1. What is the difference between this and the I-Temp version?
The main difference is the operating temperature range. This module is designed for 0°C to 70°C (Commercial), suitable for indoor use. The I-Temp version operates from -40°C to +85°C, designed for outdoor street cabinets.
2. Does this module require two separate fibers?
No, it uses a single fiber strand. Inside the module, a built-in WDM component combines and separates the four different wavelengths (1490/1310nm for GPON and 1577/1270nm for XGS-PON), allowing both services to run on one SC/UPC connector.
3. Can I use this with any SFP+ switch?
No, this is a PON OLT module, not a standard Ethernet transceiver. It must be plugged into a compatible PON OLT (Optical Line Terminal) device that supports SFP+ Combo interfaces. It will not work in a standard Ethernet switch.
4. What split ratio does Class C+ support?
Class C+ provides a higher optical budget (typically >32dB), which comfortably supports a 1:128 split ratio or long-distance links that have higher attenuation.
