Overview

The Metrobility “twister” provides seamless integration between fiber optic

multimode and singlemode segments in Gigabit Ethernet, OC-3/STM-1 or OC-12/ STM-4 environments. It supports copper to fiber translation as well as wavelength conversion from 850nm to 1310 or 1550nm, and from 1310nm to 1550nm. With the “twister”, you can increase your network reach up to 70km on a single segment. For networks that require extended distance support, use the 2152-series repeaters. The repeaters recover incoming data and regenerate the signal, thus allowing multiple hops over any distance.

The Gigabit “twister” and SONET “twister” offer the following key features:

•A Link Loss Return (LLR) switch on each fiber optic port to aid in troubleshooting remote network connections.

•Link Loss Carry Forward (LLCF) functionality on the fiber-to-fiber units or Copper Loss Carry Forward (CLCF) on the copper-to-fiber models. LLCF and CLCF work with LLR in diagnosing network connections.

•Signal recovery that restores data integrity, enabling repetition over unlimited distances. (2152-series only)

•Auto-sensing copper port that eliminates the need for crossover cables.

•Full-duplex support.

•Gigabit Ethernet (1Gbps), OC-3/STM-1 (155Mbps) or OC-12/STM-4 (622Mbps) support.

•A link LED on each port to indicate that the port is receiving idle link signals or a satisfactory level of light.

•IEEE 802.3 Sec. 14 / IEEE 802.3z compliance (Gigabit “twister” only).

•Universal desktop power supply (100-240V / 50-60Hz).

•Data transmission over singlemode fiber up to 70km.*

•Numerous connectivity options, including bidirectional wavelength division multiplexed (BWDM) fiber.

*Actual distance should be calculated based on the actual link loss budget.
