1. Introduction to optical modules1.1. Definition of optical moduleAn optical module is a device used in optical communication, which includes a light emitter and a receiver. It can convert electrical signals into optical signals and send them to remote devices, or convert received optical sig

During the use of optical modules, various problems are inevitable. When we connect optical modules through optical fibers, there may be situations such as the light port lights not working, the light port lights are red, or alarms, optical module failure, etc. Then where is the fault in the o

For hardware development engineers, there are many important optical and electrical technical parameters for optical modules, but for the two hot-swappable optical modules GBIC and SFP, only the following three main parameters of the optical module need to be understood to carry out work smoothly:Fi

Optical modules are carriers used for transmission between switches and devices, and are core components in optical fiber communication systems. Their main function is to convert electrical signals into optical signals at the transmitting end, which are transmitted through optical fibers, and then c

Serial port signals can be transmitted through optical fibers, but some conversion equipment is required to achieve this. Optical fiber transmission has the advantages of long transmission distance and strong anti-interference capability, so using optical fibers to transmit serial port signals is a

In the circuit design of 10G combo PON OLT optical modules, the power supply voltage to the CDR is 1.8V, which requires the use of a BUCK-DCDC to reduce the voltage from 3.3V to 1.8V, and the output current needs to be greater than 1A. SGMICRO recently launched a buck DCDC SGM61020 with an out

1. Does it support full duplex and half duplex?Some chips on the market can only use full duplex environments and cannot support half duplex. If they are connected to other brands of switches (SWITCH) or concentrators (HUB) and use half duplex mode, it will definitely cause serious conflicts and pac

In the realm of optical communications, dual-core optical modules have emerged as a pivotal technology, offering enhanced data transmission capabilities. However, the pairing of these modules often poses a challenge due to their intricate design and the need for precise alignment. This article delve

Customers may encounter various fault problems when using optical modules, among which the most common ones are link failure and packet loss. This article will focus on explaining the causes and solutions of optical module failures.Not working1. Optical link blockage caused by optical port pollution
