The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Over the years, fiber-based access has proven to be a cost-effective way to reach customer premises to deliver managed business and residential services. Ethernet or Passive Optical Network (PON) technologies such as Gigabit PON (GPON) are supported by the Cisco® ME Series Switches. Cisco ME Series products support any fiber-based (FTTx) access scenarios, including Fiber To The Home (FTTH), Fiber To The Building (FTTB), Fiber To The Curb (FTTC), Fiber To The cell (FTTc), and Fiber To The business (FTTb). Figure 1 illustrates the Cisco GPON solution.
Cisco GPON Solution
● Single fiber transceiver with single-mode SC receptacle
● Complies with ITU-T G.984.2 class B+ and C+
● Digital Optical Monitoring (DOM) support
● Complies with RoHS6 directive
● Point-to-multipoint
● Broadcast protocol uses TDMA
● High port density OLT at headend
● Low-cost ONT/ONU at home
● Primary market: FTTH for voice/data/video
● Low-cost passive optical splitter enables sharing of fiber, headend equipment
Platform Support
The Cisco GPON SFPs are supported by the ME 4600 Series OLT devices. For more details, refer to the document “Cisco Gigabit Ethernet Compatibility Matrix” and ME 4600 Series datasheet.
