The Nokia AOXB 474907A.101 is a high-performance, cost-effective SFP28 optical transceiver module designed for 25Gbps data transmission over Single Mode Fiber (SMF). It is a bidirectional (BiDi) module that enables 5G and LTE front-haul connectivity in Nokia AirScale and Flexi base station systems.
Technical Description for NOKIA AOXB 474907A
- Transceiver Type: SFP28 (Small Form-factor Pluggable 28).
- Design Architecture:
- Transmitter: Features a 1270nm DFB Laser, driver, and Clock and Data Recovery (CDR).
- Receiver: Consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA), limiting amplifier, and CDR.
- Connectivity: Uses a Simplex LC connector for single-fiber bidirectional transmission.
- Hot Pluggable: Supports hot-swapping via a standard 20-pin connector, minimizing network downtime during maintenance.
