Fiber optic media converteris an industrial popular device that introduced two decades ago. It is used to convert Ethernet network connection of twisted pair, coax to the multi-mode or single-mode fiber optic connection. The working principle of a fiber media converter is like: It converts the multiple forms of signals typical types such as twisted pair to the fiber optic signals. This process is very important in interconnecting the existing copper-based or structured cabling systems with fiber optic cabling. Fiber optic media converters are now widely used in LAN, MAN access and more outer networks.

Come to basically, why we need the fiber media converter to be involved in the signal transmission of the Ethernet networks? The main reason is, the Ethernet signals is primary transmitted by UTP cables, but UTP cables have some shortcomings, its transmission distance is 100 meters only, which can not meet for the requirement in many actual network nowadays, on the contrary, fiber cables are able to transmit signal for a very long distance. Besides, the fiber optic signals are not easy to be interrupted which are more secured and light that in coax, twisted pair. So we need the fiber media converter or Ethernet media converter to convert the short-distance twisted pair signals to long-distance fiber optical signals and connect the copper based networks with the fiber optic networks.

The Fiber Ethernet media converters must support a variety of communication protocols such as Ethernet, Fast Ethernet, Gigabit Ethernet as well as multiple cabling types such as twisted pair, multi-mode and single-mode fiber optics. Ingellen provide a wide selection of Fiber Media Converters range from small standalone devices and media converter card to high port-density media converter chassis systems that offer many advanced features for network management.

For example,Fast Media Convertercan connect legacy 10/100BASE-T network segments to more recent 100BASE-TX or 100BASE-FX Fast Ethernet infrastructure and support 10/100Base-T and 100Base-FX ,100BASE-TX applications.

Media Converter Card is designed to be used with the Media Converter Chassis and Management Module to extended copper to fiber, multimode to multimode and multimode to single mode fiber. These robust and feature rich products are designed to be used in high-density applications where a large number of Fiber Converters require centralized configuration and monitoring.

Gigabit Media Converteris a 1000M converter that used in Gigabit Ethernet as copper to fiber conversion equipment. It is used in high-speed high stability 1000Base Ethernet which support 1000BASE -T to 1000BASE-FX/TX fiber connections.

Media converter chassis is mainly used to manage the various media converters, we have 14 slot optic media converter chassis and 16 slot optic media converter chassis. Both of them have single power supply & dual power supply. 14 slot type media converter chassis could use stand alone type converter to plug into it, 16 slot media converter chassis use is slot type converter to plug into it. Different types of module type media converter developed by our company can be inserted into this rack and all converters used with chassis are hot pluggable.

In the modern society,video multiplexerplays an important part in most public places and special events to monitor and record the real-time videos. Video, after years of development, has become one important way of communication after audio. Video multiplexer, as the typical application of videos, has also played an important party in improving the office efficiency technology, and in many ways have mature application.

At first, let see what’s exactly a video multiplexer, to be simple, a video multiplexer is an transmission device that convert 1 to more channels analog video signals to optical signals using various encodes and finally enable them transmit via the optical fiber medium. Since two technologies are usually used for this conversion, it can be divided into analog video multiplexer and digital video multiplexer. The principle is to modulate the signals to the light and transmit through fiber optics.

The video multiplexer encodes the multi channel video signals and convert them to optical signals to transmit on optical fibers, fiber-optic video multiplexer can simultaneously transmit 1-64 channels of 8bit digitally encoded video/return or bidirectional data/ un-directional or bidirectional audio/ Ethernet/ Telephone/ Dry contract over one multi-mode or single mode optical fiber. These multiplexers are typically used in applications where the cameras have PTZ capabilities.

The Classification of the Digital Video Multiplexer
Supported channels: there are 1, 2, 4, 8 channel video multiplexers and more channel video multiplexer with PTZ control data

Single types: there can be divided into digital video multiplexer and analog video multiplexer.

Interface types: there are 1-64 channels Video multiplexer, Video+Data Multiplexer,Video+Audio MultiplexerandVideo+Audio+Data multiplexer, Phone Multiplexer, Ethernet Multiplexer, etc.

SDH Multiplexer (Synchronous Digital Hierarchy, Synchronous Digital series) capacity is biger, general 16 e1 to 4032 e1.

PDH Multiplexer(Plesiochronous Digital Hierarchy, quasi synchronous Digital series) is small capacity multiplexer and generally used in pairs, also called point to point application, capacity is commonly 4E1, 8E1, 16E1.

SPDH Multiplexer (Synchronous Plesiochronous Digital Hierarchy) is between PDH and SDH. It is a PDH transmission system that based on the PDH code speed adjustment principle at the same time, use as far as possible parts of the SDH network technology.

With the development of technology and the increasing demand on security, the Monitoring multiplexers are widely applied for most security applications such as remote business meeting, distance education, hospital, and many other security engineering applications. Current multiplexer technology is becoming more and more mature, the monitoring multiplexer can achieve in a core optical fiber transmission on multiple video, audio, data, telephone, Ethernet, E1 signal, alarm and so on many kinds of signals.

Optical transceiveris an Ethernet transmission media converter unit which transfer a short distance twisted pair electrical signals to optical signals over long distances swap, it is also calledthe photoelectric converter (Fiber Converter) in many places.

Single-mode fiber optic transceivers: 20-120 km transmission distance. Multimode fiber transceiver: transmission distance up to 2 km. According to the optical fiber, it can be divided into multi-mode fiber optic transceivers and single-mode fiber transceiver. Since the different optical fiber the fiber transceivers used, the transmission distance is different. Generally, the multimodetransceiver transmission distance is within 2 km while the single-mode transceiver range from 20 km to 120 km. What should be noted is that due to the different transmission distance, so as thetransmission power of the fiber optic transceiver itself, the receiver sensitivity and the working wavelength: Transmitting power of a 2 km fiber optic transceiver is generally between -20 ~-14db,receiver sensitivity -30db with 1310nm wavelength; 120 km fiber-optic transceiver transmitting power is between -5 ~ 0dB receiver sensitivity -38dB, using a wavelength of 1550nm.

According to the required number of optical fiber, they are single-fiber optical fiber transceivers that the received data are transmitted on a single fiber. The essence of an optical multiplexeris to achieve the electro-optical, photoelectric conversion with the images, voice or data signals. To be simple it is just a transmission between electrical signal and optical signal, the purposeis to make various signals transmitted in optical fibers. From the transmission principle, Optical multiplexer can be divided into two kinds: analog multiplexer anddigital multiplexer. The formalmainly modulate and demodulate image, voice or data signals by frequency modulation, amplitude modulation and finally output. While the digital multiplexer is transmit by analog-to-digital,digital-to-analog conversion (i.e., 0,1 / 1,0 digital encoding process).

Optical fiber as the transmission medium of optical multiplexer and transceivers, it features small signal attenuation, long transmission distance, good confidentiality, strong anti-interferenceability, etc. The optical multiplexer that available on the current market can not only transmit muli-channel video, data and voice signals on a single core fiber but also but also achieve thetelephone, computer network, E1 (2M) port, network management, and many other functions transmitting on it, which have saving lots of fiber resource. What’s more the optical multiplexer has thesame function with a network video server, which can transmit video and network data at a same time. Besides, the optical multiplexer is also regarded as an universal device that can used to formeither a LAN or a public network.

It offers custom service for SFP transceivers with the required specifications provided like OC-3/STM-1/155M SFP, OC-12/STM-4/622M SFP, OC-48/STM-16/2.5G SFP, 1.25G SFP, 4G SFP, etc. In the below list, you will have a more particular knowledge of OC-3, OC-12 andOC-48 SFPtransceivers.

Optical Carrier(OC) transmission rates are a standardized set of specifications of transmission bandwidth for digital signals, that can be carried on Synchronous Optical Networking (SONET) fiber optic networks. Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. Thus, the speed of optical-carrier-classified lines labeled as OC-n is n × 51.84 Mbit/s.

Optical Carrier classifications are based on the abbreviation OC followed by a number specifying a multiple of 51.84 Mbit/s: n × 51.84 Mbit/s => OC-n. For example, an OC-3 transmission medium has 3 times the transmission capacity of OC-1. According to the the abbreviation OC, OC transmissions can be divided into OC-1, OC-3, OC-3c / STM-1, OC-12 / STM-4, OC-24, OC-48 / STM-16 / 2.5G SONET, OC-192 / STM-64 / 10G SONET and OC-768 / STM-256. Along them, OC-3, OC-12 / STM-4 and OC-48 / STM-16 / 2.5G SONET are the most commonly used in networking.

OC-3 SFP
OC-3 SFP moduleis a network line with transmission speeds of up to 155.52 Mbit/s(payload: 148.608 Mbit/s; overhead: 6.912 Mbit/s, including path overhead). Depending on the system, OC-3 is also known as STS-3, STM-1 (SDH). OC-3 SFP modules are often used for Fast Ethernet, SDH/SONET and FTTx applications.

OC3 SFP module is specifically designed for the high performance integrated duplex data link over single mode optical fiber. These transceiver modules are compliant with the SFP Multisource Agreement (MSA). With the hot pluggability, these modules offer an easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipments operating online.

OC-12 SFP
OC-12 SFP is a network line with transmission speeds of up to 622.08 Mbit/s (payload: 601.344 Mbit/s; overhead: 20.736 Mbit/s). OC-12 lines are commonly used by ISPs as Wide area network (WAN) connections. While a large ISP would not use an OC-12 as a backbone (main link), it would for smaller, regional or local connections. This connection speed is also often used by mid-sized (below Tier 2) internet customers, such as web hosting companies or smaller ISPs buying service from larger ones.

OC-48 SFP
OC-48 is a network line with transmission speeds of up to 2488.32 Mbit/s (payload: 2405.376 Mbit/s (2.405376 Gbit/s); overhead: 82.944 Mbit/s). With relatively inexpensive interface prices, and being faster than OC-3,OC-12 SFPconnections, and even surpassing gigabit Ethernet, OC-48 connections are used as the backbones of many regional ISPs. The OC-48/STM-16 capabilities on the Cisco ONS 15600 Series consist of two optical line cards, providing interface specifications that meet the varied application needs of the service provider.

Interconnections between large ISPs for purposes of peering or transit are quite common. As of 2005, the only connections in widespread use that surpass OC-48 speeds are OC-192 and 10 Gigabit Ethernet.

OC-48 is also used as transmission speed for tributaries from OC-192 nodes in order to optimize card slot utilization where lower speed deployments are used. Dropping at OC-12, OC-3 or STS-1 speeds are more commonly found on OC-48 terminals, where use of these cards on an OC-192 would not allow for full use of the available bandwidth.

Ingellen also offers various type of fiber optic devices, including all kinds of fiber optic transceivers, video multiplexers, media conventers and passive components and so on, which are all high performance but low price.
