Multi-Mode Iso Translation (MIT) OptoIso Patch Panel

Multi-Mode Optical Isolation


CBM of America, Inc. is very pleased to announce another new member of its family of "OptoIso Patch Panel Protection" products. In addition to protecting central office network elements that are connected to Lucent Technologies CO/SAM's and Cisco router asyncronous connections, the new CBM Multi-Mode Iso Translation (MIT) OptoIso patch panel can now provide optical isolation for high density asynchronous/synchronous interfaces such as RS530, V.35, and RS232.

The new MIT OptoIso patch panel protects CO network elements that are connected to the widely used Applied Innovation AI-180 Switch, Cisco 2600/3600 router and Lucent Technologies 5E switch.

The MIT OptoIso patch panel, not only optically isolates, but also provides a translation function which allows for switch selectable input and output

  device interfaces. For example, the MIT card can be easily jumpered so that an input interface such as RS232 can be translated to output a V.35 interface, RS530 or any of a multitude of supported interfaces. This functionality provides great flexibility and allows for a wide variety of toll and switch network elements to be shared and protected by a single optoIso patch panel.

CBM designed the OptoIso patch panel to address the problem of ground plane violations which are caused when network elements, such as switch and toll elements, share the same patch panel, but are using separate power/ground sources. This situation violates the isolated ground plane and creates a potential for ground loop surges, which can cause intermittent problems, and in some cases, extensive damage to the attached network element.



Designed for Expandability

  • Each Universal CO Chassis (UCC) support up to twenty individually isolated MIT cards.

Ensures For Maximum Protection

  • Each MIT module provides up to 1000 volts of port to port isolation.

Provides Wide Translation Flexibility

  • Each MIT module's input and output interfaces are individually configurable to support the following interface standards.
    V.35, V.36, RS232, RS530, RS422, RS449

Supports High Transfer Data Rates

  • The MIT module can support data rates of up to 120 KB.

Display Status & Activity Indicators

  • The MIT's front panel has (7) LEDs that display control & data functions that quickly identify port to port circuit status and line activity.
  Allows for Adaptability

  • A four port adatper is available that allows for the isolation of ports that are connected to the widely used Applied Innovation AI1961/X interface card.

Meets NEBS Level 3 Compliancy

  • Ensures for safe system integrity and operation within the central office.
