1. Introduction

The OptiQwave-8310 is a license-exempt (5.725~5.850GHz) digital microwave in ISM band

that provides STM-1 point-to-point wireless connections at the range of 1~50 km with high

availability. It complies with FCC Part 15, Subpart C 15.247 & 15.249. Fiber Logic allows you

to quickly add backhaul and backbone connections to your infrastructure. Because it is wireless,

Fiber Logic’s OptiQwave 8310 offers significant cost-savings compared to traditional leased lines.

In addition, fast deployment opens up new revenue streams and enables faster customer acquisition.

It also provides a time-to-market advantage when installing a leased-line is too costly or impossible.

3. System Features

The unit can be placed at desktop or rack-mounted on the standard 19” or 23” rack. LED

signals are located at the front panel indicating system status.

This system contains digital modem/demodem unit, transmission unit, antenna unit and

operation management unit.

The system is modular based, including power module, LCD module, baseband module, digital

modem module, RF RX module, RF TX module, and transmission module. Every module

protects from wrong insertion.

The transmission unit, N-type connector, can be connected via coaxial cables or waveguide.

Built-in SNMP Agent: Via the 10/100BaseT interface located at the rear panel or the

FiberLogic GUI interface (operated in PC Windows 98TM and above OS), system configuration,

network performance monitoring, and loopback can be performed.

The unit operates at 5.725~5.850 GHz unlicensed frequency. The RF channel uses Frequency

Division Duplex FDD mode, which utilizes different frequencies upstream and downstream.

The system has 1 set (A1 channel and A2 channel) of transmission channels. See section 5.1

for details.

Hot Stand-by automatic protection can be proivded when two OptiQwave microwave units are

connected to FiberLogic’s OptiQwave 8155 Protection Switch.

The output power of the transmitter is at least 17dBm, and with 10dB adjustable range. The

stability of the transmitter is ±20ppm.

The threshold value of the Receiver is -73dBm (at 10-6 BER) or lower. The maximum

acceptable signal is up to -15dBm (no bit error) or higher. In addition, the system gain is up to

90dB.

The unit supports AGC test point. Please refer to Section 12-3 for the diagram of the

relationship between AGC and RF Receive Level.

The TPL and RSL can be read from the LCD screen located at the front panel. They can also

be measured from the Test Point at the front panel.

The system conforms to FCC Part 15, Subpart C 15.247 & 15.249 standard.

The system uses 32 QAM modulations. It provides SDH STM-1 capacity (155.52Mbps), one

orderwire, and one Remote RS-232 interface.

SDH interface can be configured as STM-1 optical or STM-1 electrical, at user’s discretion.

SDH STM-1 conforms to ITU-T G.707, G.703, G.957, and G.958.

STM-1 background quality level can be up to BER≦10-10.

Statistics report of SDH STM-1 interface (ES, SES, B1ERR). The performance monitoring

intervals include the current 15 minutes, the past 24 hours at 15-min increments, and 7 days at

24-hour increments. Should the readings exceed the threshold values, alarm will be generated.

Local maintenance personnel can communicate with the remote personnel via handset or

headset at any time without dialing the PSTN.

Remote system maintenance can be performed via the Remote RS-232 interface.

LCD Front Panel Functional Keys: System configuration, path performance and monitoring

can be controlled via LCD control panel interface.

Built-in menu-driven local console port: Use of CID interface connected with VT-100 terminal

to do system configuration, view system status, system monitoring, and loopback tests.

When using dial-up modem, the connection can be seen as dial-in or dial-out. When it is

dial-in, maintenance personnel can dial at anytime, connect the remote SDH STM-1 Digital

Microwave via PSTN. Dial-out connection means that the system will dial-out and alert the

maintenance personnel should certain values exceed the threshold settings. The default alarm

trigger threshold is set as 5. Users can change the value.

Built-in SNMP Agent: Via the 10/100BaseT interface located at the rear panel or the

FiberLogic GUI interface (operated in PC Windows 95TM and above OS), system configuration,

network performance monitoring, and loopback can be performed.

Additional EOC channel is available. It does not use the transmission capacity. EOC channel

ensures that maintenance can be carried out in a non-intrusive manner.

Remote system monitoring, maintenance & configuration can be performed by the local unit.

Via the microwave chain, the Ethernet interface at both sides has bridge capability. Using

back-to-back connection, local personnel can maintain the chained microwave systems. The

bridge function can be enabled or disabled.

System configuration is stored in NVRAM (Nonvolatile Memory). Configurations are

reloaded automatically when power failed and back again.

Local loopback and remote loopback can be performed for SDH STM-1 interface. Local

loopback can be performed for Radio interface. In addition, PRBS test pattern is available for

testing purpose.

Under some system alarm status, the SDH MS-AIS signals will replace the normal SDH

STM-1 signal output (AIS-Out mechanism) in order to alert the next level SDH network.

Please see Section 7.2.1 for details.

The equipment provides alarm and status LEDs at the front panel for at-a-glance system status.

Provide RADIO, and SONET/SDH major alarm and minor alarm visual and audio relay

output.

The unit can be powered by AC, DC or AC/DC power source. The acceptable range is

90V~240V for AC and –48V for DC.

System date and time are merely for the report of alarm and statistics. It is free with the Y2K

problem and won’t cause any system malfunction.

Operation temperature :0～50℃. Humidity: 0%～90%, non-condensing.

EMI - Conform to FCC Part15, Subpart B, Class B; CISPR22 Class B.

Mux/Demux ：

Multiplex the sigals from Remote RS-232, order wire, Bridge Packet,

STM-1 data into high-speed electrical signals, and transmit to RF

transmitter after it is 32 QAMed. RF receiver will then demultiplex it

back to Remote RS-232, Order wire, Bridge Packet, and STM-1 data

singals.

Modulator ：

Use 32 QAM modulation. It modulates the baseband signals from

multiplexer to 32 QAM signals and fees to the RF transmitter.

Demodulator ：

Demodulate the 32 QAM signals into baseband signals and feeds to the

demultiplexer.

RF Transmitter ：

Feeds the 32 QAM signals to antenna.

RF Receiver ：

Trasnmit the RF signals to demodulator for processing.

Test point ：

This is where it computes AGC, RSL and TPL values from the voltage

measured.

CPU ：

system control center, it controls BUS components, performs executive

functions, and etc.

NVRAM ：

Non Volatile RAM.

Keypad ：

CPU will decipher the status of Key/SW, and execute the according

command.
