The GOIUB is the GSM Optic Interface Unit for the Abis interface. It can be installed in slots 18-27 in the GMPS/GEPS. The GOIUB can be configured in pairs and work in active/standby mode.
GOIUA/GOIUB/GOIUP/GOIUT(OIUa) Panel
The physical boards of the GOIUA, GOIUB, GOIUP and GOIUT are the same. After being loaded with different software, the physical boards perform different functions. These boards have the same appearance and the same LEDs and ports.
LEDs on the GOIUA/GOIUB/GOIUP/GOIUT(OIUa) Panel
The physical boards of the GOIUA, GOIUB, GOIUP and GOIUT are the same. After being loaded with different software, the physical boards perform different functions. There are four LEDs on the panel of each of these boards: RUN, ALM, ACT, and LOS.
Ports on the GOIUA/GOIUB/GOIUP/GOIUT(OIUa) Panel
This describes the panel of the optical interface boards. The GOIUA, GOIUB, GOIUP, and GOIUT use the same physical board but perform different logical functions by loading different software. These boards have the same ports. Of the four ports, one port is labeled RX/TX, one 2MO, one 2M1, and one TESTOUT.
Technical Specifications of the GOIUA/GOIUB/GOIUP/GOIUT(OIUa)
The technical specifications of the GOIUA/GOIUB/GOIUP/GOIUT consist of the optical port mode, optical port type, wavelength, transmission rate, transmission distance, output power, and receiver sensitivity.
