product introduction
ST fiber patch cord is a common fiber optic cable with ST (Straight Tip) connectors at both ends. It is mainly used for optical signal transmission connection between devices. ST connector is a circular connector with a bayonet (Bayonet) locking mechanism. After insertion, it needs to be rotated 90 degrees to fix it.
Product Features
- High-precision Connection
ST fiber patch cord uses precision ceramic ferrules with a diameter tolerance of ±0.1μm, which is much better than the ±0.5μm of plastic ferrules. This makes the alignment error between the fiber cores no more than 0.07μm, thereby reducing the insertion loss to 0.2dB-0.3dB. In contrast, the insertion loss of ordinary FC patch cords is usually 0.4dB-0.5dB.
- Bayonet Locking
ST fiber patch cord adopts a bayonet locking structure. This structure can provide a pull-off force of more than 50N. In contrast, the pull-off force of traditional threaded FC connectors is usually between 30N-40N. ST fiber patch cords can maintain a stable connection for more than 2 hours at 10-55Hz and 1.5mm amplitude, while FC connectors can usually only maintain a stable connection for 1-1.5 hours.
- Low Return Loss
"Echo" is the energy of the signal reflected back. The end face of the ST fiber patch cord uses APC polishing, and the return loss can reach -65dB, which is much lower than the -40dB of ordinary PC polishing equipment. This low return loss feature ensures that even in long-distance communications of more than 40 kilometers, the signal of our equipment will not be seriously distorted due to reflection.
