Key Features of LINK-PP L9-SD3101-02CTI 155M 1×9
LINK-PP L9-SD3101-02CTI brings together industrial-grade reliability, MSA-standard pinouts, and robust optical transmission in a single 1×9 package. Engineered for harsh environments from -40°C to +85°C, the device seamlessly combines targeted 1310nm multi-mode optics, a dual SC connector, and stable 155 Mbps data handling for critical networks.
LINK-PP L9-SD3101-02CTI 155M 1×9 Optical Module
The module adheres to the standard 1×9 Multi-Source Agreement (MSA) footprint for straightforward integration into host communication boards. In addition, it incorporates CML differential inputs and outputs alongside a reliable TTL signal detect indicator for direct electrical interfacing.
L9-SD3101-02CTI: 155 Mbps Connectivity for Legacy Carrier Networks
Operating speeds of 155Mbps ensure stable throughput tailored specifically for legacy SDH STM-1 and SONET OC-3 carrier infrastructures. This defined data rate allows utility and telecom transport systems to preserve predictable, low-latency transmission across operational lines.
L9-SD3101-02CTI Module with 1310nm Wavelength
The internal 1310nm FP laser transmitter matches standard optical windows on multi-mode fiber. Together with a built-in PIN photodiode receiver, this wavelength ensures low signal loss and clear optical reception.
Transmission distances reach up to 2km across standard 50/125μm multi-mode fiber without signal boosters. This reach is ideal for short-to-medium range links between equipment inside large factories, substations, and office buildings.
L9-SD3101-02CTI Module with Duplex SC Interface
The duplex SC receptacle establishes a secure mechanical mating path for dual-fiber patch cords. This design guarantees consistent optical alignment while maintaining solid physical retention against mechanical vibration and shock.
