Product Overview

STEP-2PFEW is one of the EPON optical network unit design to meet the requirement of the broadband access network. It applies in FTTH/FTTO to provide the data, voice and video service based on the EPON network.

EPON is the latest generations of access network technology. IEEE802.3ah is the standard protocol of EPON. The EPON standard differs from other PON standards in that it achieves higher bandwidth and higher efficiency using larger, variable‐length packets. EPON offers efficient packaging of user traffic, with frame segmentation allowing higher quality of service (QOS) for delay‐sensitive voice and video communications traffic. EPON networks provides the reliability and performance expected for business services and provides an attractive way to deliver residential services. EPON enables Fiber To The Home (FTTH) deployments economically resulting to accelerated growth worldwide.

STEP-2PFEW provide one POTS ports, two GE auto‐adapting Ethernet ports and one 802.11 n/b/g Wi‐Fi port. The STEP-2PFEW features high‐performance forwarding capabilities to ensure excellent experience with VoIP, Internet and HD video services. Therefore, the STEP-2PFEW provides a perfect terminal solution and future‐oriented service supporting capabilities for FTTH deployment. It has good third‐party compatibility to work with the third party OLT, such as Huawei/ZTE/Fiber home/Alcatel‐Lucent.
