Electrical connections and power are supplied via the Apple Attachment Unit Interface (AAUI) 14-pin D sub-connector. Compact size allows these transceivers to connect to most Apple computers and printers as well as other PCs and networking hardware through the integral cable with AAUI connector plus latch, bringing fiber optic cabling to the desktop.

The CentreCOM Micro Transceivers allow the utilization of fiber optic media and are completely transparent to the user hardware and software. These micro transceivers can be combined with existing copper-based Ethernet configurations to allow coax-to-fiber and fiber-to-fiber local and remote network connections. These fiber optic micro transceivers contain a number of technical innovations including an automatic receive light level adjustment. This allows any length between 0-2000 meters of fiber optic cable to be attached without the use of optical attenuations. In addition, the transceivers monitor and report the low light level condition according to IEEE 802.3 10BASE-FL/FOIRL Media Attachment Unit (MAU) specifications. With this feature, these transceivers do not require any gain or energy adjustments for installation. Other enhancements include an auto-reset jabber feature, which indicates a controller malfunction. If invoked, this function causes an automatic shutoff of the unit to avoid overloading the network. The CentreCOM Micro Transceivers also employ Surface Mount Technology (SMT) to provide a highly reliable, yet inexpensive fiber optic micro transceiver. The CentreCOM Micro Transceivers are equipped with five diagnostic LEDs so status may be determined at a glance.
