1394640-1 2-2141577-1 MOST Automotive Fiber Optic Connector
1394640-1 denotes a JINSHANG TECH MOST fiber connector or transceiver socket used to terminate automotive plastic optical fiber in infotainment networks.
JINSHANG TECH supplies the 1394640-1 as a production item; fiber diameter, jacketing, connectorization and length can be confirmed against the specification before ordering.
Key Characteristics
- Housing/jacket color: Black
- Attenuation rated at less than 180 dB/km over the operating wavelength
- Operating temperature range: -55°C~+85°C
- Connector/interface: MOST CONNECTOR
- Loop and bypass variants close the ring when a node is removed
- Positive latch that holds the fiber seated across the MOST ring
- Vehicle-qualified housing resistant to vibration and temperature cycling
- Precision-aligned POF interface for low-loss automotive optical links
Typical Applications
The 1394640-1 is commonly used for MOST infotainment rings in passenger cars and commercial vehicles. The result is a reliable, repeatable build that tolerates the routing, vibration and repeated handling typical of production installations.
Frequently Asked Questions
Q: Is it plastic or glass fiber? A: MOST25 and MOST150 optical rings use 1 mm plastic optical fiber (POF), so these connectors are designed for large-core POF alignment.
Q: Which vehicles use it? A: MOST optical rings appear across many European and Asian infotainment platforms; match the part number and pinning to the vehicle and node.
Q: What is a loop/bypass connector for? A: When a MOST node (such as a head unit or amplifier) is removed, a loop/bypass connector closes the optical path so the rest of the ring keeps operating for diagnosis.
Q: What is a MOST connector? A: A MOST connector terminates the plastic optical fibers of a vehicle's MOST multimedia ring, aligning the large-core POF between infotainment devices with low loss.
