Following points are important from work execution perspective, same may please be noted.

i) Fiber optic approach cable (FOAC) shall be laid with 132kV cable system strictly as per approved method of construction i.e MOC.

Each run of FOAC shall be of continuous length, no in between splicing is allowed.

ii) Two to Three rings of extra loop length shall be kept buried underground at foot of both end termination tower after laying FOAC

cable with 132kV cable as per MOC.

iii) FOAC cable length remain outside and above the ground level shall be 2 times the height of each termination tower at both end.

Each run of FOAC cable coming out after laying in underground section should be brought up to third cross arm of termination tower

after passing it through HDPE pipes and properly tying up with tower. Also, each run of FOAC cable shall be terminated in individual

joint box on each termination tower.

iv) Balance length of each FOAC cable (i.e. Approximately half of tower height) after bringing out the FOAC cable above from ground

level and up to third cross arm of termination tower, it shall be managed in rings properly with fixing clamp arrangement to hold up it

on end termination tower.

v) As per standard GETCO format of "End to End test.pdf" , after laying FOAC cable, each length shall be tested for end to end test

using power meter and OTDR. Original copy of Test report duly sealed and signed with date, name & designation of testing person,

executing contractor and witnessing officer one each from telecom as well as TR/Const. nominated from respective EE(Telecom) and

EE(TR)/EE(const.) respectively, shall be submitted to under signed & one copy to respective telecom unit, invariably without fail

vi) Only after getting clearance on validity of test report submitted to this office, filed officer will take further necessary action on

commercial part.

vii) DRS (Data requirement sheet) and drawing approval shall be taken for FOAC & joint box before kick starting any erection activity.

The work executing contractor must have to do correspondence on eamil to concern EE (Const.) with copy to project & engineering

department, corporate office, GETCO for necessary concurrence and intimation about to start erection/laying.
