How do you extend optical fiber?
Answer
Optical fiber can be easily extended by using a Z3C-TD1 Optical Fiber Relay Connector.
However, the optical loss from the Relay Connector reduces the maximum transmission distance for the Optical Link Modules and Optical Data Links.
The optical loss is 2 dB per Relay Connector, which corresponds to 333 m of PCF fiber cable.
The following formula provides the total fiber length over which transmission is possible when a Relay Connector is used.
Total length ≦ Maximum transmission distance when no relay is used − (equivalent optical fiber length [333 m] × No. of Relay Connectors)
Example:
Communications over up to 1 km are possible if PCF fiber is used without relays when a Z3R Optical RS-232C Link Module is used as the Optical Transmission Module. The following diagram shows the total possible transmission distance if the Z3C-TD1 Optical Fiber Relay Connectors are used.
Note: "Equivalent optical fiber length" means that an optical loss of 2 dB corresponds to a fiber length of 333 m.
