EPON vs GPON: Which Is Better?
There is no rejecting that EPON and GPON are the most mainstream variants of Passive Optical Networks utilized today, they enjoy the key benefits that settle on them as the decision for every administrator. Notwithstanding, if you were uncertain with regards to which innovation would best suit your organization then you might need to know how they look at different perspectives.

We take a deep dive into how EPON and GPON systems are different from each other. We will judge these two network types across various parameters land compare both EPON and GPON networks in the following ways:
- Data Rates
- Quality of service
- Costs
Data Rates
EPON functions at 1.25Gbps and is also fully capable of operating at 10Gbps with a 10G-EPON. Meanwhile, GPON can operate at multiple bit-rate options and can easily transmit data up to 2.5 Gbps. Both the upstream and downstream rates are very symmetrical with EPON, whereas in GPON they can be selected depending on the requirements. This makes the GPON framework more flexible than EPON when it comes to data rates & transmission.
Quality of Service (QoS)
EPON does exclude any inalienable QoS capacity. In any case, PON frameworks aren’t actually practical for administrators without a type of QoS, thus numerous merchants that utilize EPON decide to utilize VLAN (Virtual Local Area Network) labels to take care of this issue. Nonetheless, this can be an exorbitant arrangement. GPON in any case, has incorporated QoS dealing with, which is an extraordinary benefit for some operators.
Costs Of Operations
The general expenses related with GPON and EPON frameworks rely chiefly upon the expense of the OLT, ONU/T and any detached optical parts.
The expenses of the fiber in both GPON and EPON are genuinely comparable, however, GPON optical modules can cost significantly more than that of an EPON. This is because of a couple of reasons however principally that the chipsets accessible for GPON depend on FPGA (Field Programmable Gate Array) though EPON utilizes MAC (Media Access Control) layer ASIC. FPGA is for the most part more costly and they are more enthusiastic to supplant.
