Function and feature

Generally, mini GBIC modules come with a fiber connector (both LC and SC types). The features may vary depending on the Cisco target audiences, which include;

• Digital Diagnostic Monitoring (DDM)

  They are required by the MSA (Multi-Source Agreement) to provide Digital Diagnostic Monitoring (DDM). DDM facilitates the monitoring of the optical receiver levels, temperature, voltage, and current. Every component has a predetermined threshold. If any of them is identified, the SFP raises an alarm signal. The Cisco SFP modules have an MDI/MDX (Medium Dependent Interface/Medium Dependent Interface Ext) port. It has the capacity to monitor temperature, voltage, and laser digital signals with the aid of an integrated transceiver.

• Extended Temperature Range

  Various industries operate within different temperature ranges. Therefore, the SFP modules are designed to operate within a wide temperature range of 0 - +70°C for commercial purposes. They also have an extended range of -40°C to +85 °C for industrial purposes. The temperature ranges are printed on the labels for easy identification.

• Electromagnetic Compatibility (EMC)

  To facilitate compliance with Electromagnetic Compatibility (EMC) regulations, Cisco mini GBIC are embedded with filters. The modules provide immunity against industrial electromagnetic emissions that could disrupt network devices and systems. Meeting the EMC regulations proves that the Cisco mini GBIC are safe for use in industrial environments, which helps in avoiding infractions that may lead to penalties and fines.

• Extended Hot Swappable Capability

  For users to replace SFPs without taking down the system or turning off the power, they must meet certain environmental standards to extend their hot swappable capabilities. The capabilities allow network devices to be efficient and operational. The SFP ports must conform to the hot-swappable requirements of various standards, which include NEBS (Network Equipment Building System) and Telecordia Technologies GR-63. The SFP module also needs to be plugged into a port that is not actively transmitting any traffic for the hotswap by defining an interface that can be substituted while traffic is still passing through it.
