PatchViewTM Capability

  • Special SMART LC-MPO 48 models, when used in conjunction with RiT's PatchView system, are able to scan fiber optic cabling configuration and subsequently report the connectivity status

  • Patching information is displayed on the management station for cabling
    management applications

  •  LED indicators on panels identify any two ports patched together. Extremely useful for facilitating maintenance in mid-to-large size cross-connect installations which are over-congested with patch cords

  • Computerized LED displays guide the technician when performing Moves, Adds and Changes (MACs)

SMART LC-MPO 48 Patch Panels are intelligent, high-density fiber optic patch panels that offer the option of real-time physical network management and are used in conjunction with RiT's PatchView system.  

With a footprint equivalent to one-half of a standard SC connector, the LC connector is fast becoming the answer to the market's demand for increased optical port density. Utilizing the connector's small size and rugged design, the SMART LC-MPO 48 patch panels support up to 48 fibers in just 1U of rack space.  

The certified panels are supplied fully assembled with LC-MPO fan outs. An external 14-pin connector is used to connect to the PatchView system, eliminating the need to open the drawer and invalidate the guarantee.  

An SNMP continuously scans the connectivity configuration of all the patch cords and reports to the network administrator's management station.  

Configurable rack mounting brackets allow for recessed panel mounting that further enhance cable protection.  



A rear metal bracket is provided in order to protect and secure the MPO connections on the rear side of the panel. In addition, this bracket can also be used as a cable strain relief. 

Grounding points are provided on the rear of the panel which, in conjunction with the optional F/O Cable Ground Kit, allows grounding means.  

RiT's LC SMART Jumper™ patch cords must be used in order to benefit from the advantages of the PatchView system. These cords, described in greater detail in the Fiber Optic Cables and Cords section, feature a duplex fiber cable and single copper wire in a common jacket, and an LC duplex connector with an extra spring-loaded copper contact. Regular LC patch cords can be used when PatchView scanning is not desired. 

MPO Polarity 

The following information is intended to give our customers a better understanding of RiT Technologies’ recommendations regarding the MPO polarity methods as described the ANSI/TIA 568-C.3 standard.  

Listed below are three fiber routing methods for maintaining polarity.


Method A:

Figure 1 – Method A


All MPO connectors mate through adapters which facilitate key-up to key-down orientation. 

Primary trunks are built with both MPOs installed in the standard ribbon fiber cable position.  

Maintaining correct polarity for multiple duplex transceivers 

Two distinct types of patch cords are needed to interconnect to the transceivers on each end: 


  1. On one end: Standard duplex patch cords are usedA to B.

  2. On the other end: Straight pair positioning duplex patch cords are used which do not reverse the fiber positions A to A.  

  • Benefits of Method A
    1. This method reduces the manufacturing complexity of the primary trunk. 
    2. Requires only one type of transition module. 
  • Drawbacks of Method A 
    1. This method requires the use of two distinct types of patch cords. This introduces an opportunity for installation error and creates an added cost and logistical burden of managing two types of patch cords in the inventory.  
    2. Using an MPO connector, key-up to key-down configuration, does not allow use of an angled polished (APC) single-mode connector.

Method B:


Figure 2 – Method B

All MPO connectors mate through adapters which facilitate key-up to key-down orientation. 

Maintaining the correct polarity for multiple duplex transceivers
System polarity is managed in the primary trunk. The trunk has an MPO connector installed in the standard ribbon fiber cable at both ends; except that the ribbon fiber cable on one end incorporates pair-wise fiber flips.


  • Benefits of Method B:  
    1. Only one type of transition module and patch cord is required. This simplifies inventory practices for the manufacturer, distributor and end-user.  
    2. This method eliminates possible installation errors compared with other methods that require different types of modules or patch cords on opposing ends.  
  • Drawback of Method B
    Manufacturing complexity, which is a transparent matter to the-user.

Method C:


Figure 3 – Method C


All MPO connectors mate through adapters which facilitate key-up to key-down orientation.  

Primary and extender trunks are identical to those used in Method A. However, Method C employs a special twisted cable between couples. (See table below).  

One module is identical to that used in Method A and Method B, while the second module is used to manage system polarity. However, by using pair-wise fiber flips within the module (as shown below) this can be achieved. Method C employs 568-C.3duplex patch cords on both ends.


  • Benefits of Method C  
    1. Requires only one type of patch cord.  
    2. Easily facilitates migration to parallel optics.  
  • Drawbacks of Method C
    Requires a specialcable twisted between couples. This creates added costs.

RiT Technologies Recommendation 

Since the polarity in Method B is managed in the trunk, and not in the MPO-LC module, it is the preferred solution for wiring and inventory use.
