Question 1

What are the core optical and electrical specifications of the Huawei 10G-1310NM-1.4KM-SM-SFP+ transceiver?

Accepted Answer

The module (SKU: HW-OPT-10G-SFP-1.4KM) features an SFP+ form factor, operating at a nominal central wavelength of 1310 nm across dual rates from 9.8304 Gbps (CPRI Option 7) to 10.3125 Gbps (10GE). Engineered with an uncooled DFB laser and PIN photodetector, it delivers up to 1.4 km reach over standard G.652 single-mode fiber (SMF). Key optical parameters include a transmit optical power between -8.2 dBm and 0.5 dBm, receiver sensitivity better than -14.4 dBm, and receiver overload of at least 0.5 dBm, yielding an optical power budget of 6.2 dB. Operating on a 3.3V DC rail, typical power dissipation is below 1.0 W. It fully supports SFF-8472 digital diagnostic monitoring (DDM) for real-time tracking of Tx bias, optical power, and internal supply voltage.

Question 2

How does this transceiver perform in terms of chassis compatibility and slot-mixing in BBU/RRU architectures?

Accepted Answer

Engineered specifically for wireless fronthaul (CPRI/eCPRI), the HW-OPT-10G-SFP-1.4KM features native Huawei EEPROM encoding for seamless plug-and-play operation in BBU3900, BBU3910, and BBU5900 baseband processing boards (e.g., UBBPd, UBBPe, UBBPg), as well as RRU/AAU outdoor remote radio units without triggering signature alarms. Fully compliant with SFF-8431 and SFF-8432 MSA standards, it supports multi-rate auto-negotiation down to CPRI Option 3/4/7. It can be populated alongside standard 10 km (LR) SFP+ optics on the same baseband blade; integrated ESD clamping and controlled inrush current mechanisms prevent power bus transient dips and neighboring-port bit errors during hot-swapping.

Question 3

What extreme environmental durability and hardware reliability designs are engineered into this 10G 1.4km module?

Accepted Answer

Designed for harsh outdoor telecom environments, this module supports true industrial operating temperatures from -40°C to +85°C (-40°F to 185°F). The optical sub-assembly employs hermetically sealed TO-can packaging with anti-sulfuration passives and specialized high-temperature optical adhesive, preventing moisture condensation during steep thermal cycling. It complies with IEC 60068-2 shock and broad-band vibration standards, tolerating mechanical stress on tower-mounted RRU/AAU deployments. An all-metal die-cast zinc alloy housing delivers superior EMI/EMC shielding, withstanding 4kV contact and 8kV air electrostatic discharge (ESD) to maintain front-haul uptime during severe electrical storms.
