Packing Details

Components are packaged using a high-protection tray system. Each tray contains 20 products, and a full box contains a total of 140 pieces across 7 trays. To ensure maximum component safety and space efficiency, each subsequent tray is rotated 180 degrees horizontally relative to the previous tray. The standard box dimensions are L340 x W265 x H200mm.

FAQ

Q1: How does this connector help manage the heat generated by optical transceivers? A: The cage uses a precision open-frame structure that acts like a “dedicated air conditioner” for transceivers. It is designed to maximize natural air convection, which has been measured to reduce the operating core temperature of modules by 5-8°C, preventing thermal-induced performance drops.

Q2: Is the S1N3A23000CA4 suitable for use in harsh outdoor environments? A: Yes. The product is engineered for environmental adaptability and has been validated through temperature/humidity cycling, salt fog, and aging tests. Its robust mechanical design and high-quality plating ensure it remains “fearless” in the demanding conditions typical of 5G outdoor base stations.

Q3: Does this product support signal monitoring for network maintenance? A: Absolutely. The S1N3A23000CA4 is designed to be fully compatible with standard transceivers that support Digital Diagnostic Monitoring (DDM) and Digital Optical Monitoring (DOM). This allows network operators to monitor real-time parameters such as temperature and optical power for preventative maintenance.
