Description
FEATURES
TFC, Token Ring Fiber Optic Converter, provides electrical-to-optica
l and optical-to-electrica
l conversion of an IEEE 802.5 signal, for communication over an optical link. Transmission distance can be up to 3 km (1.9 miles) for multimode and 20 km (12.4 miles) for single mode.
An infrared LED transmitter converts the IEEE 802.5 electrical signal into an optical signal. At the receiver end, the optical signal is converted back into an electrical signal.
TFC can be operated in various modes: - RI/RO mode: connects between adjacent Token Ring access units, such as S-TAUs via a fiber optic link - Lobe mode: converts the copper lobes of any access unit/hub to fiber lobes - Station mode: connects station to the optical lobes of the RADring TL-2/F module - Satellite mode: connects workgroups over a single fiber connection.
In Station mode, the insert/bypass command, originating at the Token Ring Adapter card in the form of a "phantom" current, is carried through the fiber using special signaling.
TFC is available in two versions: - Stand-alone unit (TFC-SA) - Card for installation in S-TAU (TFC) TFC can also be installed as a module in the RADring hub (RR-TFC). (See the RR-TFC data sheet for additional details).
The stand-alone model has an integral power supply. The stand-alone unit is wall-mountable using the TR-WM brackets, or can be mounted in a 19" rack using the TR-RM hardware. This hardware can support up to four TFC units (see Ordering).
Multimode or single mode fiber optic options are available for both the stand-alone and the S-TAU card versions. In addition, an internal media filter is provided for the UTP option.
The TFC card for S-TAU is installed in the Ring In or Ring Out port of the Access Unit. The card is powered by a wall-mounted, external power supply. TFC provides an optical link between two S-TAUs. Alternatively, for start topology, the TFC card can provide an optical link between the lobe of a RADring and the Ring In port of another S-TAU.
Where retiming and jitter attenuation are required, the TFC operates with the TLR-FO for lobe conversion.
Fail-safe operation is provided by performing an automatic loop to the backup path, upon power off detection or optical signal loss detection.
Indicators include power on and fault indication for optical signal loss condition.
