The Opnext V50017-U324-K500 is a hot-pluggable SFP (Small Form-factor Pluggable) optical transceiver module designed for intermediate-reach applications in SDH/SONET and multiservice transport platforms, including equipment from Nokia Networks and compatible systems. It provides a single bidirectional optical interface operating at multirate speeds, primarily supporting 1.25 Gbit/s (Gigabit Ethernet / 1000BASE-LX or equivalent STM-4/OC-12 class) with backward compatibility for lower rates.This module operates at a nominal wavelength of 1310 nm using a Fabry-Perot or DFB laser transmitter and a PIN photodiode receiver. It is optimized for single-mode fiber (SMF 9/125 µm, OS2) with a typical transmission distance of up to 40 km. The optical link budget supports reliable performance with low bit error rates over this reach under standard fiber attenuation conditions. Transmitter output power and receiver sensitivity are aligned with intermediate-reach (IR or LH/EX) specifications commonly used in metro and regional networks.
The V50017-U324-K500 complies with SFP MSA (Multi-Source Agreement) and relevant ITU-T / IEEE standards for optical interfaces. It handles framed signals with appropriate overhead processing when installed in a compatible host platform. The transceiver supports digital diagnostic monitoring (DDM/DOM) compliant with SFF-8472, enabling real-time reporting of transmitted and received optical power, laser bias current, temperature, and supply voltage via the I²C interface for advanced performance monitoring and fault management.
Optical connectivity is provided 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 capability. The module uses the standard 20-pin SFP electrical interface with a 3.3 V power supply and low power consumption (typically below 1 W), making it suitable for high-density line card deployments.
Environmental specifications meet carrier-class requirements with a commercial operating temperature range of 0°C to +70°C, high humidity tolerance, and integrated protection against ESD and electrical surges. This SFP is primarily deployed for point-to-point intermediate-reach links in add-drop multiplexers, optical transport nodes, or as a tributary/up-link interface in metro networks. It ensures full interoperability with Nokia Networks and third-party compatible platforms while integrating with element management systems for remote provisioning, alarm reporting, and detailed performance data collection.
Installation requires standard fiber optic cleaning procedures, correct transmit/receive fiber polarity, and adherence to minimum bend radius for patch cords. The Opnext V50017-U324-K500 offers a compact, reliable, and cost-effective solution for 1.25 Gbit/s optical transport over single-mode fiber up to 40 km in telecom infrastructures.
