Introduction The Metrobility Gigabit “twister” and SONET “twister” represent the latest technology available for extending Gigabit Ethernet, OC-3/STM-1 and OC-12/STM- 4 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. In addition to the standalone unit, the “twister”

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 rec

On the fiber-to-fiber convert- ers (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. Copper Loss Carry Forward (CLCF) Switch

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 informa- tion about the cable lengths supported by each model, refer to the table in the Technical Specifications section. When making connections, be sure that the transmit (TX) optical conductor of the “twister” connects to the receive (RX) optical conductor of the connected dev

OFF PWR ON DC INPUT/5VDC Upon receiving power, the “twister” goes into normal operation mode. Verify valid connections via the PWR LED on the front panel. If an additional extension cord is used to connect the power supply to the outlet, follow the guidelines below. While one end of the AC power cord can be fitted with whatever plug is standard for the country of operation, the end that connects to the “twister” unit’s power supply must have a female plug that fits this type of AC receptacle. •

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 trouble- shooting and overall network diagnosis and management. When lit, the LEDs indicate the following status: • PWR (power): The unit is powered ON. • LINK (Port 1): Port 1 is receiving idle link signals

Link Loss Return (LLR) The fiber ports on the “twister” have been designed with Link Loss Return function- * ality 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. The diagram below shows a typical network configuration with goo

Link Loss Carry Forward (LLCF) The fiber-to-fiber “twister” units incorporate LLCF functionality to assist in trouble- * shooting 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. The diagram below shows a typ

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. N
