Introduction The Metrobility Gigabit “twister” and SONET “twister” represent the latest technology available for extending Gigabit Ethernet, OC-3/STM-1 and OC-12/STM4 networks. Since Metrobility first developed “twister” media conversion, it has set the standard for providing affordable means of integrating mixed media networks. As LANs/WANs grow and evolve, this technology provides an ideal solution for building effective migration strategies.
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.
Installation Guide Follow the simple steps outlined in this section of the guide to install and start using your Metrobility “twister”. Unpack the “twister” and Accessories Check that the following components have been included: • • • • Metrobility “twister” Power supply Power cord Four (4) rubber feet Your order has been provided with the safest possible packaging, but shipping damage does occasionally occur. Inspect your order carefully.

By default, all DIP switches are disabled.
LLCF is enabled when the LLCF switch is in the ON position. The fiber-tofiber repeater is shipped with LLCF disabled. On the fiber-to-fiber converters (2151-AD-, 2125-xx- and 2135-34-01), LLCF is always enabled and cannot be disabled. Sliding the LLCF switch up and down on these models has no effect. LLCF is not applicable to the copper-to-fiber repeaters. For more information, refer to Link Loss Carry Forward in the User Guide section of this manual.
Fiber Optic Interface Multimode ports are labeled MM. Singlemode ports are labeled SM. Extended distance ports are labeled LH (Long Haul) or ELH (Extended Long Haul). Each fiber port provides an SC or LC connector. For information about the cable lengths supported by each model, refer to the table in the Technical Specifications section.

User Guide This section contains more detailed information regarding the operating features of the Metrobility “twister”. LED Indicators The Metrobility “twister” provides three LEDs on the front panel for the visible verification of unit status and proper functionality. The LEDs also aid in troubleshooting and overall network diagnosis and management. When lit, the LEDs indicate the following status: • PWR (power): The unit is powered ON.
Link Loss Return (LLR) The fiber ports on the “twister” have been designed with Link Loss Return functionality for troubleshooting remote connections. When LLR is enabled*, the port’s transmitter (TX) shuts down if its receiver (RX) fails to detect a valid receive link. LLR should only be enabled on one end of a cable and is typically enabled on either the unmanaged or remote device. LLR works in conjunction with LLCF and CLCF.
Link Loss Carry Forward (LLCF) The fiber-to-fiber “twister” units incorporate LLCF functionality to assist in troubleshooting a remote connection. When LLCF is enabled*, the ports do not transmit link signals until they receive link signals from the opposite port. When a lost link signal is returned to an unmanaged “twister” unit, that lost link must then be carried forward to a managed device (switch/hub) for trap generation. LLCF works in conjunction with LLR.
Copper Loss Carry Forward (CLCF) The copper-to-fiber “twister” incorporates CLCF for identifying a lost copper connection. When CLCF is enabled*, the fiber port’s transmitter shuts down if the copper port stops receiving link pulses. However, the copper port continually transmits link signals regardless of whether or not the fiber port detects link. The diagram below shows a typical network configuration with good link status using two copper-to-fiber “twister” units for remote connectivity.
