Fibre Optic No. Link Name From To OPGW Cable length (Km) OPGW Cable length (Km) (+5% + 1km) SFP Type 0.22d B/Km loss at 1550n m 0.35d B/Km loss at 1310n m Link Losses (dB) Splice loss @ 0.05dB per splice per 3KM Conn ector loss (dB) Optical Path penalty (dB) Mainte nance Margin @ 0.025d B/Km Total loss Tx power End Of Life (dBm) Rx Sensitivi ty (dBm) Availa ble Power (dB) Receiv ed Power (dB) Margin for future (dB) 2.3.8.2 Link Performance The Link performance for ES, SES and BER for the fibre optic links shall correspond to National Network as defined in ITU-T G.826. 2.3.8.3 FODP to SDH Equipment/Optical Amplifier Connectivity The Contractor shall be responsible for connectivity between the FODP and the SDH equipment. The Contractor shall provide FC PC coupled patch cords. The location of FODP shall be finalized during detailed engineering. The patch-cord length between the FODP & equipment rack shall be suitably protected from rodents, abrasion, crush or mechanical damage. 2.4 MDF, DDF and Cabling For the purposes of the specification, the contractor shall provide cabling, wiring, DDF patching facilities and MDFs interfacing to the wideband telecommunications system. Equipment and material components for MDF, DDF and cabling are also part of this procurement. It shall be the Contractor's responsibility to provide all cable support required for full supplied equipment interconnection with the MDF and shall be in accordance with communications industry standard practices and the requirements mentioned in the technical specifications. 2.4.1 MDF and DDF Patching Facilities The Contractor shall supply and install all cabling, wiring, connectors, cross connects, Digital Distribution Frames (DDF) and Main Distribution Frames (MDF) associated with the installation and interconnection of equipments procured under this package, (i) DDFs for termination of V.24/V.28 ports with DB25 connectors. (ii) MDFs for termination of all the E&M subscriber channels on Krone IDC blocks. All subscriber channels shall be provided with GD tubes. (iii) Cabling and connectors required to enable subscriber-to-subscriber circuits over the telecom network. The Line side of the MDF shall be cabled to the Primary Multiplex and the equipment side shall be cabled to the MDF of the assigned subscriber (PLCC, PABX, Telephone at wideband locations etc). (vi) Any other cables, connections etc required for a fully functional, integrated telecom system. Sign & Seal of Bidder GETCO/E/TS-SDH/PDH FOTE/R1, Dt:16.04.2011 Page 36 of 60
TECHNICAL SPECIFICATION FOR SDH/PDH Equipment with integrated Access Multiplexer The connections amongst various equipment such as FOTE and subscriber MDFs etc shall always be routed through DDF and MDF to provide maintenance access. 2.5 Patch Cords The Contractor has to supply FC PC coupled Patch cords as described in BOQ. The Patch cord return loss shall be equal to or better than 40 dB and insertion loss equal to or less than 0.5 dB. 2.6 Network Management System The Bidder shall provide a Network Management System (NMS) for operational support to the FOTE. This NMS shall provide the capability to monitor, reconfigure, and control elements of the telecommunications network from a centralized location (RLDC) as well as at remote operation location (SLDCs) and at each node of the network (through craft terminal) where equipment is located. Network management is crucial for the overall performance and availability of the communication network. The task of the network management system (NMS) is to provide complete and efficient supervision of the alarm state of the network (fault management), to facilitate the adaptation of the configuration to changing needs (configuration management) and to strictly control the access to the various NMS features (security management). 2.6.1 Applicable Standards The NMS design concept, functional and informational architecture and physical architecture, shall be in compliance with ITU-T Recommendation M.3010. 2.6.2 NMS Architecture a) The Network Management System (NMS) should be structured according to the NMS Logical Layered Architecture established in section 5 of ITU-T Recommendation M.3010 (05/96) and cover the Element & Network Management layers of this architecture. The system should be designed using a client-server paradigm and use a SQL complaint Database to store alarm and configuration data. Access to the system shall be possible for many users at the same time using NMS Client software. Client software shall be installed on the server machine itself and on separate client PC. The NMS Server machine shall be located at ALDC Jetpur along with 2 operator consoles. The distance between ALDC Jetpur and 400KV Jetpur is around 300 mtrs. Appropriate convertors/cables/interfaces shall be provided by the bidder to achieve the connectivity between the equipment and the NMS server. One operator console shall be provided at SLDC Gotri. Ethernet connectivity between ALDC Jetpur and SLDC Gotri shall be provided by GETCO. b) Platform and Redundancy The NMS server software should be based on a secure operating system (Linux/Unix). The NMS software with license for managing total nodes of SDH Sign & Seal of Bidder GETCO/E/TS-SDH/PDH FOTE/R1, Dt:16.04.2011 Page 37 of 60
