The Metrobility Chassis Platforms provide a flexible, scalable and manageable means for integrating coax; Category 3, 4 or 5 twisted pair; and singlemode or multimode fiber optic LAN segments into Ethernet, Fast Ethernet, Gigabit Ethernet, SONET and TDM environments. Metrobility offers four chassis platforms to support its wide range of interface and access line cards.
Designed for desktop or wall mount use in any modern office, this versatile device auto-negotiates from 10Mbps to 100Mbps, allowing existing 10Mbps devices to communicate over a 100Mbps backbone. Network administrators enjoy the benefit of retaining existing 10Mbps devices while upgrading segments of the network as needed. As a media converter, the unit supports mixed media networks by enabling copper-to-fiber media conversion.
On select models, bidirectional wavelength division multiplexing (BWDM) offers an interface that carries two separate channels in different directions through a single strand of fiber. BWDM eliminates the need to install a second fiber and effectively doubles the fiber capacity on existing fiber cables.
Unique Troubleshooting Features
Network technicians can now test the integrity of the entire fiber line using the remote loopback feature on the fiber port reducing cost and time. LED indicators for Far End Fault also show whether the remote fiber port is receiving a valid signal from the local unit.
When Link Loss Carry Forward (LLCF) is enabled, the ports do not transmit a link signal until they receive a link signal from the opposite port.
Unparalleled Operational Features
The Delta Class AutoTwister offers un-paralleled performance over long distances - up to 100km - through retiming of the signal. Delta Class integral retiming reduces any jitter to ensure data integrity. Additional features include shared network segment isolation, and auto-negotiation of duplex and speed configurations.
The Delta Class has a sleek new design that incorporates a lightweight, impact resistant enclosure that is made of high durability, fade resistant engineered plastic. The unit is wall mountable and provides channels for cable and power cord management and cable protection. Link and activity LEDs are easily viewed on the top cover.
The unit meets all domestic and international EMI and EMC (static electricity) requirements and passes EN60950 safety and impact standards.
By utilizing state-of-art technology in both the electronics and the enclosure, the Delta Class AutoTwister offers a cost-effective product in a rugged lightweight enclosure with superior feature advantages.
Metrobility R643/2643 10/100Mbps AutoTwister® line card and standalone
Metrobility's 10/100 AutoTwister® provides versatile connectivity for evolving network infrastructures being upgraded from existing 10Mbps copper-based networks to 100Mbps fiber networks. The AutoTwister provides media conversion and 10/100 rate adaption in a single unit, extending copper-based networks up to 100km over singlemode fiber. Now you can achieve all the features of 100Mbps fiber, such as distance and security, while minimizing costs in a mixed media environment.
As a rate adapter, the card auto-negotiates from 10Mbps to 100Mbps, allowing existing 10Mbps devices to communicate over a 100Mbps backbone. This allows network administrators to retain existing 10Mbps devices while upgrading segments of the network as needed. As a media converter, the card also supports mixed media networks by enabling copper-to-fiber as well as fiber-to-fiber media conversion.
All models incorporate Link Loss Return (LLR) and selected models also offer Metrobility's Auto-Recovery and Link Loss Carry Forward (LLCF) features to enable troubleshooting remote locations. LLR stops sending link pulses from the transmit port when link pulses are not being received. Auto-Recovery, used in conjunction with LLR, enables the card to restart the fiber link after a link loss event without a costly troubleshooting trip.
Additional features include shared network segment isolation, and auto-negotiation of full and half duplex configurations. Bi-directional Wavelength Division Multiplexing (BWDM) is also available to utilize a single strand of fiber to send and receive a two different wavelengths, doubling the capacity of the fiber (refer to Metrobility BWDM datasheet).
The AutoTwister is available for Radiance chassis platforms and as a standalone unit to provide seamless connectivity with all major switch and router manufacturers. It offers a cost-effective solution for fiber connectivity in copper switches to lower the cost per port without sacrificing function.
