ZTE OL16 x1 Optical Line Board

The ZTE OL16 x1 is a high-density Optical Line Board designed for carrier-grade transport and access platforms, including the ZXUR 9000 and ZXMP series. This module serves as a critical interface component, providing 16 high-speed optical ports for the transmission and reception of synchronous and asynchronous data streams. It is engineered to facilitate the aggregation of optical traffic from remote radio units (RRU) or lower-level network elements into the core switching fabric of the subrack.The OL16 x1 board performs essential physical layer functions, including optical-to-electrical (O/E) conversion, clock recovery, and frame alignment. It supports various optical interface standards via SFP (Small Form-factor Pluggable) transceivers, allowing for flexible deployment over different fiber types and distances (Short Haul/Long Haul). The module integrates advanced SDH/MSTP or Ethernet-over-SDH processing capabilities, enabling the efficient mapping of packet data into synchronous transport containers while maintaining strict timing and synchronization standards.
Designed for maximum network reliability, the OL16 x1 supports various protection mechanisms, including 1+1 path protection and sub-network connection protection (SNCP). The front panel is equipped with a comprehensive set of LED indicators for per-port link status (LNK/ACT) and overall board health (RUN, ALM), allowing for rapid on-site diagnostics. As a mission-critical interface unit, it supports hot-swappable installation, enabling capacity expansion or maintenance without disrupting the system's power supply. The board complies with international ITU-T, ETSI, and NEBS standards for optical performance and electromagnetic compatibility.
