Embodiment Construction

[0013] Such as Figure 1~4 As shown, this optical fiber transceiver consists of RJ-45 interface RJ1, coupler T, and 802.3u standard two execution chips U 1 , U 2 , Optical fiber signal transceiver module U 6 , Transceiver working status display LED s , 25MHz crystal oscillator U 8 , three-state gate circuit F, resistor group R, regulated power supply S and socket J 1 , an optical fiber signal interface 2, a printed circuit board and a housing 1. The received optical signal passes through the optical signal receiving end of the optical fiber signal transceiver module through the optical fiber signal interface, and the photoelectric conversion output of the optical fiber signal transceiver module passes through the first execution chip U 1 Decoding---resistor group (R 3 ~R 7 )---the second execution chip U 2 After encoding from U 2 The twisted pair transmitting ports TPON and TPOP are connected to the primary of the coupler receiving group, and the secondary of the coup...

Abstract

The optical fiber transceiver adopts CSMA/CD mode, operates on IEE 802.3u standard and has two executing chips U1 and U2. The received optical signal is fed through optical fiber interface to the optical fiber signal transceiving module and the electric signal output by the transceiver is fed to the receiving port of RJ45 interface through U1 to decode, the resistor combination, U2 to encode, the twisted pair and one coupler. The signal to the emitting port of RJ45 interface is fed to the transceiving module through U2 to decode, the resistor combination, U1 to encode, and from LED of the transceiver, optical signal is emitted through the optical fiber interface to network. The optical fiber transceiver uses four-layer PCBs.

Description

(1) Technical field [0001] The invention relates to an optical fiber transceiver. (2) Background technology [0002] Ethernet (Ethernet) is a local area network (LAN) technology widely used in the range of several kilometers. According to statistics in 1996, there were more than 40 million nodes worldwide. It has the advantages of easy upgrade, high reliability, low cost, rich network software, strong system function, simple installation and connection, and convenient use and maintenance. With the increase of program and data storage, the resource requirements are getting higher and higher, and the throughput from the network to the PC is also increasing. 10Mbps Ethernet can no longer meet the needs of today's network. The emergence of 100Mbps Fast Ethernet in 1995 not only increased the transmission rate by 10 times, but also provided many network interfaces that can support 10Mbps and 100Mbps operations and continue to automatically switch, making it easy to upgrade Ethe...
