transmission rod routes are generally optical fiber cables and power cables mixed into one pole for transmission.1.3 SDH TransmissionSDH is called the Synchronous Digital System, which unifies the rate level, network node interface NNI, and frame structure of digital communication. SDH is to synchronous transmission module STM form to transmit, according to the level divided into STM-1: 155 Mbit/s (155), can accommodate 63 2 m; STM-2: 622 Mbit/s (

manufacturers, currently, ATT, alcatel ibm, NT, and Digital products are widely used. 1. ATT sans IMAX has three categories, five categories, cat5e UTP unshielded twisted pair cable, information socket, adapter, photoelectric distribution frame and other products, can support 10 Mbps, 155 Mbps (STM-1 level) 622 Mbps (STM-4 level) end-to-end application, UTP cable characteristic impedance is 100, using unshielded twisted pair balanced characteristics

The access network technology is still quite common, So I studied the narrow band passive optical network in the access network technology. Here I will share it with you and hope it will be useful to you. ATM-PON has the following technical features: ◆ ATM-PON network topology is star, two-way transmission is generally used dual-fiber Air Division Multiplexing SDM), also based on Single Fiber Wavelength Division Multiplexing WDM. Point-to-multiple-point propagation uses the downstream time-divis
