Ethernet Repeater (TL)

PWR IN ETH I/R PWR OUT TL-ER TechnoLabs Ethernet Repeater is a new system that can be used on existing Ethernet cabling to transparently drive Ethernet communications beyond the maximum permissible IEEE 802.3 Ethernet distance. Traditional 10/100/1000 Base-T Ethernet Networks utilize CAT5e copper cabling which has a distance limitations of 100 meters between geographically separated LANs.
In many cases: across a campus, in a Metropolitan Area Networks (MANs), along a NSN Ethernet Radio system a Repeater is need to extend high speed Data Communication Range between the generic IDU (InDoor Unit) and ODU (OutDoor Unit). The several performances, implemented in the Ethernet Repeater, give us the possibility to extend the cable distances up to 200 meters with a single Repeater or up to 300 meters with two Repeaters in cascade. In a NSN radio applications: IDU, ODU and Repeater units can be considered as a single segment through the network.
Network segments linked with the Repeater function together as a single local area network (LAN) system on a same collision domain

Repeater Features & Benefits

  • Ethernet line extension up to 300 meters

  • Signal Restoring symmetry and amplitude

  • Signal Retiming prevents excessive jitter accumulation in the signal

  • Six Ethernet protocols 10/100/1000 Base-T full or half duplex

  • Power line extension

  • Internal PLL for synchronous “Ethernet - Timing Mode” link.

  • Stand alone model

Better Networking

The powerful microprocessor on the repeater board enables software upgradation and supports a rich set of capabilities including :

  •  MDIO Management Data Input/Output

  • MDC Management Data Clock

  • Control and Failure of the two Ethernet links IDU‹—›TL-ER and TL-ER‹—› ODU

  • Command to switch the roles of the master and slave line.

Network optimization

TL-Repeater system helps operators optimize the network performance by adjusting the signal amplitude on each segment : IDU‹—›Ethernet Repeater ‹—›ODU. It can be used in different types of network topologies: single repeater for covering distance up to 200 m, two repeater in series for covering distance up to 300m.
The last function is obtained by putting back to back two Physical Ethernet sub-modules. The connection between these modules is performed by a Reduced formed Gigabit Media Independent Interface (RGMII).
