The media converter will automatically re-establish the link when connected to switches if the link is lost, even with Auto-Negotiation and Link Pass-through (both directions) enabled.

Full-Duplex flow control

In a full-duplex network, maximum cable lengths are determined by the type of cables used—see page 1 (front cover) for M/GE-PSW-xX-01 cable specifications.

The 512-Bit Rule does not apply in a full-duplex network.

Note: Full duplex is ON permanently for the fiber port only.

Half-Duplex flow control (512-Bit Rule)

In a half-duplex network, the maximum cable lengths are determined by the round- trip delay limitations of each Fast Ethernet collision domain. (A collision domain is the longest path between any two terminal devices; e.g., a terminal, switch, or router.)

The 512-Bit Rule determines the maximum length of cable permitted by calculating the round-trip delay in bit-times (BT) of a particular collision domain. If the result is less than or equal to 512 BT, the path is good.

For more information on the 512-Bit Rule, see the white paper titled “Collision Domains” on the Transition Networks website at: www.transition.com

Back pressure

Back pressure is used in half duplex mode. It ensures the retransmission of incoming packets when a port using half-duplex is temporarily unable to receive incoming frames.

Flow Control

The process of adjusting the flow of data from one device to another ensures that the receiving device can handle all the incoming data. This is particularly important where the sending device is capable of transmitting data much faster than the receiving device can accept it.

Distance extension

The M/GE-PSW-xX-01 media converters can segment one (1) 10Base-T copper Ethernet, 100Base-T copper fast Ethernet, or 1000Base-T copper Gigabit Ethernet, and one (1)1000 Base-X fiber Fast Ethernet collision domain:

In a half-duplex Ethernet or Fast Ethernet environment, the M/GE-PSW-xX-01 media converters extend network distances by segmenting collision domains so that the 512-Bit Rule applies separately to each collision domain.

In a full-duplex Ethernet or Fast Ethernet environment, the M/GE-PSW-xX-01 media converters extend network distances to the physical cable limitations imposed by the selected twisted-pair copper fiber cables.

Rate conversion

The M/GE-PSW-xX-01 media converters allow the following connections:

•10Mb/s devices on a 10Base-T legacy copper network to 1000Mb/s devices on a 1000Base SX/LX Gigabit Ethernet fiber network.

•100Mb/s devices on a 100Base-T legacy copper network to 1000Mb/s devices on a 1000Base SX/LX Gigabit Ethernet fiber network.

M/GE-PSW-LX-01, M/GE-PSW-SX-01 specifications

Transition Networks has been a market leader in reliable connectivity solutions, particularly in the realm of media conversion. Among their offerings, the M/GE-PSW-SX-01 and M/GE-PSW-LX-01 models stand out for their robust features and capabilities. These devices help organizations transition data between different media types within their networks, facilitating seamless communication and ensuring high-speed data transfer.

The M/GE-PSW-SX-01 is designed for short-range applications. It employs a fiber-optic connection using multimode fiber optics, typically operating over a distance of up to 550 meters with a wavelength of 850 nm. This makes it an ideal choice for local area networks (LANs) where the equipment is in close proximity. Its compact design allows for easy deployment in various environments, and its plug-and-play functionality simplifies installation, requiring minimal technical knowledge.

On the other hand, the M/GE-PSW-LX-01 is tailored for long-range optical transmission using a single-mode fiber. It operates at a wavelength of 1310 nm and can cover distances up to 10 kilometers, making it suitable for wide-area network (WAN) applications. The long-range capability of the M/GE-PSW-LX-01 extends the reach of network infrastructure, allowing organizations to connect remote locations without compromising on speed or reliability.

Both models incorporate advanced technologies such as auto-negotiation and auto-MDI/MDI-X, which eliminate the need for manual configuration, ensuring that devices communicate efficiently regardless of their connection types. This user-friendly feature makes them particularly appealing for small to medium-sized enterprises that may not have dedicated IT support.

In terms of performance, both media converters support data rates of 10/100/1000 Mbps, allowing for high-speed transmission and minimal latency. They are built with durable materials to withstand varying environmental conditions, ensuring longevity and operational reliability.

The built-in LED indicators provide real-time monitoring of connection status and data traffic, enabling users to troubleshoot potential issues quickly. Overall, Transition Networks’ M/GE-PSW-SX-01 and M/GE-PSW-LX-01 represent compelling choices for organizations seeking to enhance their network infrastructure with reliable media conversion solutions. Their advanced features, long operational range, and simple setup make them invaluable in today’s fast-paced business environment, bridging the gap between various network media and technologies.
