Optical performance testing, including return loss/insertion loss testing. The test instrument can use FibKey 7602 return loss/insertion loss integrated tester.

There are three main types of fiber jumpers according to the termination type: ST-ST, SC-SC, ST-SC.

The transceiver wavelengths of the optical modules at both ends of the fiber jumper must be the same, that is to say, the two ends of the optical fiber must be optical modules with the same wavelength

Each high-speed transceiver includes two channels, a transmitter and a receiver.

The phase locked loop (PLL, phase locked loop), CDR (clock and data recovery), 8B/10B codec and other mixed-signal modules in the transceiver are designed with analog signals, such as the voltage-cont

According to the network management, it can be divided into network-managed fiber optic transceivers and unmanaged fiber-optic transceivers.

A transceiver is a device for signal conversion, usually referred to as a fiber optic transceiver.

In order to ensure the compatibility and stability of the equipment, each optical data acquisition system (including the main link optical splitter, the duplicated link optical amplifier, and the dupl

Optical splitter, also known as OBD, is a passive device that accesses FTTH. Generally, operators in the communication industry need to access and use it on the home broadband side.

The application environment of the optical splitter requires the use of the environment: -30~65℃, RH 5-95%.

Atomic absorption spectrometers do not have high requirements on the resolution of the spectrometer.

From the perspective of human health and environmental protection, it can also be divided into UVA (315 ~ 400nm), UVB (280 ~ 315nm), UVC (below 280nm).
