An important standard indicator of Barron is its balance, which is the degree to which two balanced outputs (one is 180 ° inverted output and the other is non inverted output) are close to the ideal state of 'equal power level, 180 ° phase difference'. The phase angle di...

Balun is a three port device, or a broadband transmission line transformer that connects balanced and unbalanced transmission line circuits by converting matching inputs into differential outputs. The function of Barron is to enable the system to have different impedance...

Both the buck circuit and the boost circuit are important circuits in hardware design, especially for intelligent ONUs and OLT devices. The VOICE function in ONU design uses the boost circuit to directly boost the voltage and supply power to external phones. The best way...

Antenna gain: The gain coefficient is a parameter that comprehensively measures the energy conversion and directional characteristics of the antenna. Its definition is: The product of directional coefficient and antenna efficiency is denoted as: D is the directional coef...

Antennas convert electrical signals transmitted by devices into electromagnetic waves for transmission. Generally, antennas have the function of transmitting and receiving, but in special cases, they only perform the function of receiving. (such as broadcast antenna) The...

The optical module consists of optoelectronic devices, functional circuits, optical interfaces, etc. The optoelectronic devices include transmitting and receiving parts. In brief, the role of the optical module is photoelectric conversion. The sending end converts the el...
