GPON OLT SFP transceiver module
Port Type

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.

GPON (Gigabit Passive Optical Network) is a type of fiber-optic access network that uses passive splitters to enable a single fiber to serve multiple endpoints. GPON is a point-to-multipoint access network that uses optical splitters to divide the fiber link into multiple downstream channels. An SFP GPON OLT (Optical Line Terminal) is a device used to terminate the fiber link and provide the interface between the GPON network and the customer premises. It provides the necessary optical and electrical interfaces to connect to the GPON network and the customer's equipment. It also provides the necessary control and management functions to manage the GPON network. SFP GPON OLT is a cost-effective solution for providing high-speed broadband access to residential and business customers.

GPON OLT SFP transceiver module Applications



Benefits of Using GPON SFP

Using GPON SFP is considered a more convenient and cost-effective solution for the end customers.
And it also reduces the devices that need to be provided by the Internet service provider (ISP).It benefits both the service providers and the end users to some degree.


GPON SFP: Class B+ vs. Class C+

GPON SFP transceivers are categorized into GPON OLT SFP and GPON ONT SFP or GPON ONU SFP depending on the devices they are used in.And there are Class B+ GPON SFP and Class C+ GPON SFP. The major differences between them are the transmit power and the receive sensitivity.

GPON SFP: Class B+ vs. Class C+


The transmission mode of GPON SFP

One GPON OLT SFP at the Central Office communicates with multiple GPON ONT SFPs with the help of fiber opticsplitters.
