Huawei TNN1HUNS304 Smart 40G Line Service Processing Board

Huawei OptiX OSN7500 II TBH1HUNS304 Smart 40G Line Service Processing Board (SH,Tx _ -7dBm ~ 2.3dBm, Rx_-13.7dBm, LC, with 10G license) Part number 03030PUM or 03055298

1. Technical Description & Features for HUAWEI TNN1HUNS304 board

• Universal Switching: Supports unified transmission of both Packet (MPLS-TP) and TDM (SDH) services.
• PID Technology: Integrates OTU, MUX, and DEMUX functions on a single chip, simplifying network design by removing the need for complex wavelength planning or OSNR calculations.
• Service Density: Provides one physical OTU3 port that can be virtually mapped to multiple services (e.g., 10GE, STM-64).
• 10G License: This specific board is hardware-capable of 40G but is restricted to 10 Gbit/s throughput. Full capacity can be unlocked by adding three additional 10G software licenses.

3. Optical Transceivers and Modules Information for HUAWEI TNN1HUNS304 board

• Connector Type: Duplex LC connector for high-density fiber patches.
• 40G Line Side: Uses OTU3 encapsulation compliant with OTL3.4 standards.
• Wavelengths Supported:
  • Short/Medium Reach (10/40 km): 1271 nm, 1291 nm, 1311 nm, and 1331 nm.
  • Long Reach (80 km): 1531.12 nm, 1537.4 nm, 1543.73 nm, and 1550.12 nm.
• FEC Support: Supports standard Forward Error Correction (FEC) and Enhanced FEC (EFEC) to improve transmission quality over long spans. 
  This HUAWEI TNN1HUNS304 board primarily uses CFP (C Form-factor Pluggable) transceivers for its 40G line-side interface. Below are the standard modules used to achieve different transmission distances:

  Module Type	Huawei Part Number	Interface	Fiber Type	Max Distance	Wavelength
  CFP-40G-LR4	02310MAM	40GBASE-LR4	SMF	10 km	1310 nm
  CFP-40G-ER4	02310QFE	40GBASE-ER4	SMF	40 km	1550 nm
  PID-40G-LH	Internal/Fixed	Line-Side	SMF	80 km	DWDM (C-Band)

   Technical Notes for Transceivers

  • 10G License Restriction: Although you are using a 40G CFP module, the 10G license on your board will limit the data throughput to 10 Gbit/s. The hardware remains 40G-ready.
  • Connector Type: These modules utilize the Duplex LC connector as specified in your board description.
  • Encapsulation: The modules support OTU3 (Optical Channel Transport Unit 3) mapping, which is standard for the OSN 7500 II line-side transmission.
