Technical parameters of the system parameters Technical indicators maximum capacity of 16 single-wave systems, 32 waves, 40 waves, wave length range of 48 consistent with ITU-I G.694.1 standard service access type PDH, ATM, SDH (STM-1 ~ STM-64) O -192 / ~ OC-3 FE, GE, 10GE, FICON / ESCON / FIBER Channel / CATV optical interface transmission using 3R transmission, single rate optional support 125Mbps ~ 10Gbps physical network topology point to point, point to multi- point links, loops, Bidirectional G.652 G.653 G.655 fiber type NMS CLI, TELNET, SNMP, WEB Size 2U OTU card 25 (W) × 88 (H) × 116 (D) (mm) 1U passive chassis 440 (W) × 44 (H) × 230 (D) (mm) 2U chassis 428 (W) × 88 (H) × 322 (D) (mm) Environmental requirements Operating temperature -10 ℃ ~ 60 ℃ Storage Temperature -40 ℃ ~ 80 ℃ Relative humidity 5% to 95% non-condensing Power Requirements (target value) 220 V / AC, 50Hz; -48 V / DC (optional) Safety and EMC compliance with FCC, UL , CE, TUV, CSA standard power 10G filled with ≤60W Technical Services (1) According to our user requirements, with the builders to complete the project installation and commissioning work. We provide the equipment inside connections, including connections between multi-chassis and power cord supplied by the seller by the buyer is responsible for connecting, laying. (2) We provide installation and commissioning of the systems engineering required information, including the construction drawings, construction programs, technical consulting, on-site technical support, technical information. (3) For each batch of equipment during installation and technical support services, we will depend on the number of sites, sending at least one engineer to complete the work, and on-site staff for guidance. Service costs (including from the factory to the site of round-trip travel, daily expenses) will be included in the business offer. (4) During the installation commissioning and technical support services, equipment failure, we will deal with immediately. (5) The warranty period shall provide 7 × 24-hour technical service (6) we were on a different level of fault response. Fault level and response times are as follows: a) one, business interruption caused by equipment failure or paralysis of the entire system, a response within 30 minutes. Within 300 km 12 hours arrived at the scene within 24 hours of troubleshooting, recovery systems. 300 km outside of 24 hours to reach the scene, troubleshooting within 36 hours to restore the system. b) two, due to operational failure seriously affect system response within one hour, within 48 hours of troubleshooting, recovery systems c) three, due to a fault affecting the efficiency of the system, but the system can run response within 8 hours, 60 hours within troubleshooting d) four, due to a software upgrade, some features on the system did not materialize, but does not affect the business and restore the quality assurance system within 72 hours after the final inspection we provide the complete two-year warranty period, the warranty period I responsible for all equipment warranty except consumables outside. Since the year of our reasons for internal design, production, packaging, and other aspects of quality problems caused by the date of the product from the factory, the company responsible for repair or replacement.
