About This Part
The Nokia FGLT-B C+ is a high-density, 16-port Gigabit Passive Optical Network (GPON) Line Termination (OLT) interface card. As a critical component within Nokia's ISAM FX series Optical Line Terminals, this module is engineered to deliver robust and scalable fiber access services. It operates on the GPON protocol, adhering to ITU-T G.984 standards, enabling symmetrical data rates of 2.488 Gbps downstream and 1.244 Gbps upstream per port. The 'C+' designation indicates enhanced optical budget and reach capabilities, typically supporting a link loss budget of 31 dB, which translates to extended service areas and higher split ratios. Each of the 16 ports supports standard GPON wavelengths, typically 1490 nm for downstream and 1310 nm for upstream data, alongside 1550 nm for RF video overlay services. This line card integrates advanced features for traffic management, quality of service (QoS), and robust security, making it suitable for demanding broadband deployments. Its compact form factor allows for efficient slot utilization within the OLT chassis, maximizing subscriber density per system. The Part Number FGLT-B C+ is primarily deployed in central office or remote cabinet environments, installed within Nokia's ISAM FX series OLT chassis, such as the FX-4, FX-8, or FX-16. It serves as the aggregation point for multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) at the subscriber premises, forming the backbone of Fiber-to-the-Home (FTTH) and Fiber-to-the-Building (FTTB) networks. Telecommunication operators, Internet Service Providers (ISPs), and large enterprise campus networks utilize this card to deliver high-speed internet, IPTV, and VoIP services to residential and business customers. This module addresses the growing demand for bandwidth, solving the challenge of providing future-proof, high-capacity access infrastructure. It is a key upgrade path for operators looking to migrate from legacy copper-based access technologies or to enhance the capacity and reach of existing GPON deployments, offering a significant improvement over earlier generation GPON cards with lower port density or optical budgets.
