GE-BD53-20KM SFP – Technology Bazar

The 19 inch form-factor small form-factor pluggable (SFP) module labeled as “GE-BD53-20KM” is a gigabit-capable optical transceiver designed for single-mode fiber links up to approximately 20 km. It supports hot-plug insertion into compatible network switches or routers and enables reliable high-speed uplinks in enterprise and service-provider environments.

Key Features:
- Supports gigabit Ethernet data rate (1.25 Gb/s) over single-mode fiber up to ~20 km.
- Single-mode fiber interface with LC connector, optimized for 9/125 µm fiber span.
- Hot-pluggable SFP form-factor, compliant with SFP-MSA standards.
- Low power consumption via single +3.3 V supply in compact metal housing.
- Digital diagnostic monitoring to report real-time optical and module parameters.

The GE-BD53-20KM SFP transceiver module offers a compact, standards-compliant solution for establishing long-reach gigabit Ethernet links over single-mode fiber. With a transmission distance of up to 20 kilometres (on 9/125 µm SMF) it is well suited for inter-building connections, campus backhaul, or network aggregation where fiber span length exceeds typical short-reach modules. The device embraces the SFP Multi-Source Agreement (MSA) hot-pluggable design, allowing network administrators to install or replace modules without powering down the host equipment.

Operating on a single 3.3 V supply and featuring low power consumption, the module reduces thermal buildup and supports high-density chassis environments. Optical signalling is achieved via LC connectors and single-mode fiber, with typical transmitter wavelengths of around 1550 nm and receiver sensitivity suitable for 20 km reach. The module also includes digital diagnostic monitoring (DDM/DOM) for real-time tracking of optical parameters such as temperature, received optical power, and transmitter bias current. Rugged metal housing ensures EMI resilience and durability in demanding networking environments.
