Transmitter Types




   Light Source:       
   Your choices are...
 
      
 
   LED
 
     Light Emitting Diodes (LEDs) have relatively large emitting areas and as a result are not as good light sources as Laser diodes.  However, they are widely used for short to moderate transmission distances because they are much more economical.
 
   Laser Diode
 
     Laser Diodes (LDs) can couple many times more power to optical fiber than LEDs.  They are primarily used for applications that require the transmission of signals over long distances.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Cable Type:       
   Your choices are...
 
      
 
   Single Mode
 
     A fiber with a small core, only a few times the wavelength of light transmitted, that only allows one mode of light to propagate. Commonly used with laser sources for high speed, long distance links.
 
   Multimode
 
     A fiber with core diameter much larger than the wavelength of light transmitted that allows many modes of light to propagate. Commonly used with LED sources for lower speed, short distance links.
 
   Single Mode / Multimode
 
     Can be used with both single mode and multimode fibers.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Connector Type:       
   Your choices are...
 
      
 
   Biconic
 
     Biconic connectors have precision tapered ends for low insertion loss.
 
   D4
 
     D4 connectors contain composite zirconia ceramic ferrules for durability. They feature a high-performance threaded mounting system and a keyed body for repeatability and intermateability.
 
   ESCON
 
     ESCON connectors derive their name from their original application, IBM's enterprise system connection (ESCON) for mainframe computers. ESCON connectors are similar to FDDI connectors, but contain a retractable shroud instead of a fixed shroud. ESCON connectors have two 2.55 mm ceramic ferrules and a robust strain relief design.
 
   FC
 
     FC connectors have an all-zirconia ceramic ferrule for durability, a high-performance threaded mounting system, and a keyed body for repeatability and intermateability. FC connectors are used primarily with single mode fibers and in telephone, instrumentation, and high-speed communication links.
 
   FDDI
 
     Fiber distributed data interface (FDDI) connectors are designed for use in FDDI networks, a LAN technology that uses dual, counter-rotating 100-Mbps fiber optic rings. FDDI connectors are duplex devices that contain two 2.5 mm ferrules. A fixed shroud protects the ferrules from damage.
 
   LC
 
     LC connectors include a polished, zirconia ceramic ferrule and a push / pull-style housing with a latching mechanism. LC connectors are half the size of standard fiber optic cable connectors. They are suitable for both public and private networks.
 
   Loopback
 
     Loopback connectors are used to test transceiver systems.
 
   MTP
 
     MTP connectors are threaded and well-suited for high density applications.
 
   MT-RJ
 
     Unlike other fiber optic connectors, MT-RJ connectors hold two fibers with a single ferrule. MT-RJ connectors are a variation of MT connectors, but use a smaller ferrule.
 
   MU
 
     MU connectors contain a ferrule with a diameter of 1.25 mm. Applications include high-speed data communications, voice networks, telecommunications, and dense wavelength division multiplexing (DWDM). MU connectors are also used in multiple optical connections and as a self-retentive mechanism in backplane applications.
 
   SC
 
     Subscription channel (SC) connectors are coaxial, medium-size devices with a constant 50Omega: Ohms impedance and a frequency range of 0 - 11 GHz. They are larger than BNC connectors, but about the same size as Type N devices.
 
   SMA
 
     Subminiature-A (SMA) connectors are intended for use on semi-rigid cables in components. They directly interface the cable dielectric without air gaps.  They are not intended for permanent connections.
 
   ST
 
     Straight tip (ST) connectors use a quick release, bayonet coupling that requires only a quarter turn to engage or disengage. Built-in keying provides repeatable performance because ST connectors always mate with a coupling bushing in the same way. ST connectors are used in FDDI cabling applications.
 
   Other
 
     Other unlisted, specialized, or proprietary fiber optic connector.

Transmitter Performance




   Data Rate:
 
     Data rate is the number of data bits transmitted in bits per second.  Data rate is a way of expressing the speed of the transceiver.
 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Transmitter Rise Time:
 
     In the approximation of a step function, the time required for a signal to change from a specified 10% to 90% of full power.  Rise time is a way of expressing the speed of the transmitter.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Wavelength:
 
     The output wavelength of the transceiver.

Transmitter Features




   Signal Input:       
   Your choices are...
 
      
 
   TTL
 
     A digital input / output, digital systems use different standard signal levels, depending on the type of logic circuits used in the system.  These logic circuits define the levels for the highs and lows that represent the 1s and 0s of digital data.  Transistor-Transistor Logic (TTL) is the most common type of digital logic used today.  TTL uses .5 V for a low signal and 5 V for a high signal.
 
   ECL
 
     A digital input / output, digital systems use different standard signal levels, depending on the type of logic circuits used in the system.  These logic circuits define the levels for the highs and lows that represent the 1s and 0s of digital data.  Emitter-Coupled Logic (ECL) is faster than TTL.  ECL circuits use -1.75 V for low signal and -.9 V for high signal.
 
   CMOS
 
     A digital input / output, digital systems use different standard signal levels, depending on the type of logic circuits used in the system.  These logic circuits define the levels for the highs and lows that represent the 1s and 0s of digital data.  Complementary Metal Oxide Semiconductor (CMOS) has very low power consumption.  Many CMOS circuits use the same voltage levels as TTL for their signals.
 
   Video
 
     The input / output of the receiver is analog.
 
   RF
 
      
 
   Other
 
     Other unlisted or speciailzed form of singnal input / output.
