Q: What are the chassis compatibility, slot interoperability, and rate-matching rules for this module within Nokia AirScale and Flexi platforms?

Pre-programmed with Nokia-specific EEPROM microcode, the module eliminates vendor-lock alarm flags and integrates seamlessly into Nokia AirScale BBUs (ASIA, ASIK system modules, ABIL/ABIO baseband cards) as well as legacy Flexi Multiradio platforms (FSMF, FBBA/FBBC). It directly interfaces with RRH/RRU/AAU optical front-end cages such as FXEB, FRGY, and AHFIB. The module is fully hot-swappable in SFP+ ports. In mixed-rate chassis topologies, it can operate alongside 6.144 Gbps (CPRI 6) and 4.915 Gbps (CPRI 5) optics in adjacent slots; however, point-to-point physical links require strict symmetric line-rate locking at 9.8304 Gbps without multi-rate auto-negotiation downshifting.

Q: How does the industrial-grade transceiver withstand extreme outdoor thermal and physical stress in tower-mounted RRU environments?

Engineered compliant with Telcordia GR-468-CORE and MIL-STD-883 standards, the module is tailored for unconditioned tower-top RRU enclosures and AAU optical cavities. It supports an extreme case operating temperature envelope of -40°C to +85°C. The ruggedized all-metal die-cast housing offers enhanced EMI shielding and ESD resilience (up to 8kV contact discharge). Internally, hermetically sealed optical sub-assemblies (OSA) and reinforced bonding resist structural vibrations up to 20G caused by mast resonance and wind shear. The duplex LC latching mechanism ensures secure physical locking, delivering a calculated MTBF exceeding 10 million hours in harsh, condensing field environments.

Question 1

What are the core optical/electrical specifications, power consumption, and link budget of the Nokia NOK-OPT-9.8G-SFP-1.4KM transceiver?

Accepted Answer

The NOK-OPT-9.8G-SFP-1.4KM is optimized for CPRI Option 7 wireless fronthaul at a fixed line rate of 9.8304 Gbps. Powered by a standard 3.3V DC rail, it maintains typical power dissipation under 1.0W across full temperature limits. Utilizing a 1310nm transmitter paired with a high-sensitivity PIN receiver, it delivers an optical launch power between -8.2 dBm and +0.5 dBm and an optical receiver sensitivity exceeding -14.4 dBm (BER < 10^-12) with a +0.5 dBm saturation limit. Operating over standard G.652 single-mode fiber (SMF), the optical budget ensures reliable 1.4 km transmission. It incorporates SFF-8472 compliant Digital Diagnostic Monitoring (DDM/DOM) reporting real-time Tx/Rx power, laser bias current, internal supply voltage, and operating temperature.
