Passive optical networks are crucial to providing broadband network access to the end user. When it comes to the passive optical network (PON), there are some differences. Based on popularity, today I’m going to demonstrate the differences between EPON Vs GPON. Let’s dive deeper into this article.

Before knowing the EPON Vs GPON Differences, let’s learn first what is EPON and GPON?

What is EPON?

The full abbreviation of EPON is Ethernet passive optical network. EPON connects computers across telecom infrastructure. GPON uses ATM cells while EPON uses Ethernet packs. This distinguishes EPON and GPON. Deployment of EPON point-to-multipoint networks in FTTP and FTTH networks. EPON uses one optical fibre channel for multipoint connections. EPON uses Ethernet packets for voice, video, and the Internet. EPON is compatible with other Ethernet standards, so no conversion or encapsulation is needed when connecting on both ends. It can easily reach 1 Gbps and 10 Gbps. It's cheaper than GPON.

What is GPON? 

The full abbreviation of GPON is Gigabit Ethernet Passive Optical Network.

The Gigabit Ethernet Passive Optical Network uses ATM for voice and Ethernet for data. GPON's downstream and upstream speeds are faster than EPON's. GPON is a broadband passive optical access standard. FTTH networks use GPON. High bandwidth, varied service options, and wide coverage make GPON popular. It's considered the best technology for achieving broadband network coverage. Both downstream and upstream can reach 2.5 Gbps. 2.5Gbps downstream and 1.25Gbps upstream is possible.

EPON vs GPON differences: 

GPON offers ATM for voice, Ethernet for data, and proprietary voice encapsulation. On the contrary, EPON uses IP to carry data, voice, and video over a single Layer 2 network. GPON promises downstream speeds of 1.25 Gbit/s or 2.5 Gbit/s and upstream speeds ranging from 155 Mbit/s to 2.5 Gbit/s. The EPON has a symmetrical 1-Gbit/s bandwidth. GPON supports 128 ONUs. EPON has no ONU limit. EPON can deliver 32 ONUs per OLT using low-cost optics or 64 with forwarding error correction (FEC). EPON is cheaper than GPON.

In a quick summary, telecommunications companies use PONs to provide TV, VoIP phones, and the Internet to subscribers. Video distribution and other Internet services need higher data rates. Passive components' low cost means simpler systems with fewer failure-prone parts. The range is limited to 20 km or 12 miles. PONs are popular as the demand for faster Internet and more video rises. EPON vs GPON have pros and cons, which have made it difficult to say which one is better. Data says GPON is popular in the U.S. Asia and Europe use EPON more.

Now, after gaining knowledge, if you decide to find some products from EPON and GPON, I have some good suggestions for you. The SmartPon brand’s EPON and GPON OLT Modules will meet demand. SmartPon is a professional manufacturer enriched with industry experience.
