coitus Neviem ci dokazes na tom lacnom OTDR odhalit utlm ale koniec vlakna (odtrhnute vlakno) to ukaze spolahlivo. Na odhalenie zalomeneho kabla mame OTDR co ma 4 vlnove dlzky za 10k Eur a to funguje spolahlivo.
tulo Dobry zvar to nenajde, ale utlm na spojke to uz vidi bez problemov. Na obrazku mas 1000m pred a 500m za trasou "predradne" vlakno
lubomaslo kde si to kupil? Nasiel som taketo cudo,co je podstatne na OTDR meraku? Preco je tam velky rozdiel v cene? https://allegro.sk/ponuka/otdr-opticky-reflektometer-v-casovej-oblasti-tester-optickych-vlakien-5-6-s7-15462234835

lubomaslo No a tu je este jeden link: https://allegro.sk/kategoria/prislusenstvo-testery-siete-4443?string=OTDR&order=p&p=2
tulo Vtedy ked som kupoval nasiel som len 1310/1550 teraz sa da najst aj 1625 a tou ked meras tak asi by to malo ist aj na zivom pone. Ci?? Neviem zatial som nemal potrebu tak som neskusal. Vzdy sme zatial merali len pred spustenim segmentu siete a mam jednotlive segmenty odpojitelne na apc spojkach takze si to viem premerat zvlast. Inak je neuveritelne ako za dva roky tie otdr zlacnely, teda ak to nie je napodobenina tej mojej napodobeniny 😁😁🙃. https://www.aliexpress.com/item/1005006813502900.html?spm=a2g0o.detail.pcDetailTopMoreOtherSeller.3.3ee6x1ltx1ltPl&gps-id=pcDetailTopMoreOtherSeller&scm=1007.40050.354490.0&scm_id=1007.40050.354490.0&scm-url=1007.40050.354490.0&pvid=8f941840-6f3b-4bf9-ab71-cb030696d8fa&_t=gps-id:pcDetailTopMoreOtherSeller,scm-url:1007.40050.354490.0,pvid:8f941840-6f3b-4bf9-ab71-cb030696d8fa,tpp_buckets:668%232846%238112%231997&pdp_npi=4%40dis%21EUR%21414.82%21137.72%21%21%213152.10%211046.48%21%40211b664d17141314015503261e4d4d%2112000038512256433%21rec%21SK%21118933000%21&utparam-url=scene%3ApcDetailTopMoreOtherSeller%7Cquery_from%3A
basty psichac a je nějaký model co má dostatečný range který prosvítí i velký splitter? Třeba 1:64? Moc jsem nemasel
psichac basty fu no, pouzivame EXFO MAX730C, ale to neviem ci potesi cenovo. Ale ako priklad parametrov asi ok 🙂 Mame aj nejaku "cinu" ale presne, pre maly dynamicky rozsah to na PONe (aj vypnutom) nebolo pouzitelne.
tulo 1:64 by mal mat splitter pod 20db utlm takze teoreticky by to mohol odmerat aj ten lacnejsi cinan pisu tam ze ma range 22 db. edit: nasiel som aj 26 db s podporou live testu: https://www.aliexpress.com/item/1005006152501584.html?spm=a2g0n.productlist.0.0.63351c32jBSS3q&browser_id=e2e0880361b54e02beb168e46b224a9a&aff_trace_key=146ba7c662be4f01aff447770057955a-1709983729572-09395-UneMJZVf&aff_platform=msite&m_page_id=xykhtlcpkocavfgn18f1debd4991d82ca089a42135&gclid=&pdp_npi=4%40dis%21EUR%211211.49%21605.74%21%21%211269.37%21634.68%21%402103094c17141939455913167ee2b2%2112000036001407828%21sea%21SK%21118933000%21&algo_pvid=bf5e9de2-f024-4c3b-ae41-04ea062fff74
wolf14 lubomaslo ak by ti to pomohlo viem ti v KK pozicat https://www.banggood.com/TM1100-A20S-Portable-Mini-OTDR-Optical-Time-Domain-Reflector-1550nm-20dB-4_3-Inch-Capacitive-Touchable-Screen-Fiber-Optic-Reflectometer-p-1856335.html?cur_warehouse=CN
lubomaslo wolf14 Uz pozeram po vlastnej číne. Ceny su uz celkom O.K. a na to co potrebujem uplne bude stacit. Ale dik kamo.
lubomaslo Len mi nie je jasne preco su tie ceny tak rozdielne u cinskych modelov aj v pripade,ze zakladne parametre su v podstate rovnake.
