EPON vs GPON<\/u><\/a>: Technical Specification<\/strong><\/span><\/p>\nOverall, the technical differences between GPON and EPON\u00a0are very small. The difference between the two is mainly on\u00a0the interface, while the\u00a0switching, network element management, user management are similar, or even the same. In comparison, GPON has more advantages in multi-service bearing and full-service operation, which is mainly due to the GPON standard is developed by FSAN, which is an operator-led organization.<\/span><\/p>\nRegarding the cost, GPON is more expensive than EPON when measured in terms of individual optical ports. However, operators mainly focus on the network construction cost, not the equipment cost. This is because in terms of bandwidth and service support capability, each GPON port can access 64 or even 128 users, while each EPON port can only access 32 users. In addition, in the actual network construction, the cost of office-end equipment accounts for less than 10%, while OLT accounts for 50%. Therefore, GPON is cheaper in terms of overall network construction cost.<\/span><\/p>\nAll in all, when we are talking about GPON and EPON, the first thing is that GPON has a larger bandwidth than EPON. Its service carrying capacity is more efficient and its optical splitting ability is stronger. However, the implementation of GPON is more complex, which leads to its higher cost compared with EPON. Luckily, with the large-scale deployment of GPON technology, the cost difference between GPON and EPON is gradually narrowing.<\/span><\/p>\n <\/p>\n
