Optical Line Protection Module
Description
 
  1. Lightwave Link Inc OLPM (Opcal Line Protecon Module) is combined with opcal switch, opcal spliter and opcal power monitoring funcon.
  2. The OLPM is consisted of one 1x2 opcal switch, one 1x2 opcal spliter and PD monitoring. The subsidiary electrical circuitries are for driving opcal switch, performing PD monitoring and demarcang PD linear range with I2C interface.
  3. The main funcon of OLPM are spling opcal signals, selecng opcal light path and monitoring the opcal power.
  4. Lightwave Link Inc OLPM comply with TELCORDIA GR-1312-CORE.
Key Features
  • Input port (IN) light signal output to TXA and TXB via 50/50 spliter.
  • Light signal is from RXA to Tap1, 2.5% for opcal power monitoring and 97.5% for transmission to 1x2 opcal switch.
  • Light signal is from RXB to Tap2, 2.5% for opcal power monitoring and 97.5% for transmission to 1x2 opcal switch.
  • Output port (OUT) will output the light signal from RXA and RXB via selected opcal path by 1x2 opcal switch.
  • The PD monitor results (analog signals) will convert to digital signals by AD convertor and output to management system via I2C interface.
  • There are opcal switch driving circuitry inside and control the opcal switch’s status via electrical pin and ming signals.
  • There is EEPROM with I2C interface to keep two demarcated PDs’ linear ranges.
  • There is online funcon inside for status judgment from management system.
  • There are 40 opcal power data in EEPROM, the opcal power of AD monitoring will compare with EEPROM and find the opcal power range then upload to management system.
Applications
  • Split the input light source to two paths by 1x2 spliter (IN→TXA/TXB).
  • Monitoring the opcal powers from RXA/RXB and feedback to management system via I2C interface.Management system will control the opcal switch via subsidiary circuitries to obtain the opcal light path selecng funcon.
