SEESUO’s GPON SFP is a series of optical transceiver modules operating in Gigabit Passive Optical Networks (GPON). From the Central Office’s (CO) Optical Line Terminal (OLT, with GPON SFP transceiver/module) a single strand of fiber goes out to a passive optical splitter where its signal is multiplied to maximum 128 different lines in GPON. SEESUO supplies OEM service and Third-Party(Cisco, Juniper, HP, Dell etc.) compatible fiber optic transceivers.
SFP-GPON-ONU-B+ typically refers to a Small Form-Factor Pluggable (SFP) optical transceiver module designed for Gigabit Passive Optical Network (GPON) Optical Network Units (ONUs) with specific features or capabilities denoted by the "+". GPON is a type of fiber optic network architecture used in telecommunications for delivering broadband access to subscribers.
The "B+" variant of GPON ONUs typically indicates certain improvements or enhancements over previous versions, such as increased bandwidth, improved performance, or additional features. However, the specific features and capabilities may vary depending on the manufacturer and model of the SFP module.
In general, SFP-GPON-ONU-B+ modules are used in GPON-based broadband access networks by service providers to connect individual subscribers to the GPON network and deliver high-speed internet, voice, and video services. These modules are typically installed at the customer premises and interface with the service provider's GPON equipment located in the central office or data center.
