Laser products are divided into 4 levels by safety level to the user.
Level 1 laser is the safest and its power is within 1 mW; under normal
conditions, it does not result in harmful radiation or fire.
In this fiber, multi-mode optical signals are transmitted.
In synchronization transfer mode, no handshaking signals, able to
communicate with RS232 or RS422 devices point to point, in
transparent transmission, with a maximum rate of 19.2 Kbit/s
In this fiber, single-mode optical signals are transmitted.
Unit of dimension, short for unit. It takes 44.45 mm as basic unit;
namely 1 U = 44.45 mm
