Siemens V50017-U406-K500 SFP+ 10GBASE-LR 1310nm 10km Transceiver

The Siemens V50017-U406-K500 is a hot-pluggable SFP+ (Small Form-factor Pluggable Plus) optical transceiver module designed for 10 Gigabit Ethernet applications in Siemens and Nokia Networks (NSN) optical transport, switching, and routing platforms. It provides a single bidirectional optical interface compliant with IEEE 802.3ae 10GBASE-LR specifications at a nominal line rate of 10.3125 Gbit/s.This module operates at a nominal wavelength of 1310 nm using a high-performance DFB laser transmitter and a PIN photodiode receiver. It is optimized for single-mode fiber (SMF 9/125 µm, G.652) with a typical transmission distance of up to 10 km. The optical link budget supports reliable performance with low bit error rates (better than 10⁻¹²) under standard fiber attenuation conditions. Transmitter output power is typically in the range of -8.2 dBm to +0.5 dBm, while receiver sensitivity meets the requirements for 10 km reach with adequate margin.
The V50017-U406-K500 complies with the SFP+ MSA (SFF-8431 / SFF-8432), IEEE 802.3ae 10GBASE-LR/LW, and related standards. It handles serialized 10 Gbit/s data streams with low jitter generation and high extinction ratio. Digital diagnostic monitoring (DDM/DOM) functions compliant with SFF-8472 allow real-time reporting of transmitted and received optical power, laser bias current, internal temperature, and supply voltage via the I²C interface for advanced performance monitoring and fault isolation.
Optical connectivity is realized through a duplex LC connector. Key operational features include Loss of Signal (LOS) detection and assertion, automatic laser shutdown (ALS) for Class 1 eye safety compliance, and hot-swap support. The module uses the standard 20-pin SFP+ electrical interface with a 3.3 V power supply and low power consumption (typically below 1.5 W), making it suitable for high-density 10 Gbit/s port configurations in routers, switches, and multiservice platforms.
Environmental specifications meet carrier-class requirements with a commercial operating temperature range of 0°C to +70°C (industrial variants may offer extended range), high humidity tolerance, and built-in ESD protection. This SFP+ transceiver is primarily used for point-to-point 10 Gbit/s Ethernet links in metro access, aggregation networks, or as uplink/interconnect interfaces in Siemens equipment.
The module integrates seamlessly with network management systems for remote provisioning and monitoring. Installation requires standard fiber optic cleaning procedures, correct Tx/Rx fiber polarity, and adherence to minimum bend radius guidelines for patch cords. The Siemens V50017-U406-K500 provides a reliable, compact, and cost-effective solution for 10 Gbit/s optical transport over single-mode fiber up to 10 km while maintaining full compatibility with legacy and current Siemens/Nokia Siemens infrastructure.
