SFP-GPON-B-I — SFP 1.244/2.488 Gbps

The SFP-GPON-B-I is a Cisco SFP module for Class B+ GPON networks, offering throughput of 1.244 Gbps upstream and 2.488 Gbps downstream over single-mode fiber with a reach of 20 km. Its industrial temperature range of -40 to 85 °C clearly differentiates it from the standard version, while ITU-T G.984.2 Class B+ compliance positions it for optical access infrastructures with moderate link budgets.

This module is recommended for operators deploying GPON outdoors or in street cabinets where temperature swings are significant. Class B+ offers a good balance between reach and cost for residential and SME FTTH networks. Genuine Cisco hardware, manufacturer warranty.
