In accordance with the ITU-T G.694.1, it maximizes the capacity of the C-band range.","brand":"Refurb Squared","offers":[{"title":"C37-C52, Duplex, 4.6dBFMU","offer_id":51507277693216,"sku":"1-3160-c37-c52,-duplex,-4.6dbfmu","price":3923.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/3157\/9936\/files\/20251216121746ctc0cs_jpg_3ee6f5e8-910c-4ba9-a6ac-7ffd5cbc37de.webp?v=1776868941"},{"product_id":"1-3161-190-75-196-65thz-duplex-6-0dbfmu","title":"60 Channels Odd DWDM Mux Demux, Super C-band 100GHz 190.75-196.65THz, with Monitor Port, 6.0dB Typical IL, LC\/UPC, Dual Fiber, FMU 1U Rack Mount","description":"\u003cstrong\u003eDescription\u003c\/strong\u003e\u003cbr\u003eThe 60CH Mux Demux, based on AAWG (Flat-top), is a passive DWDM device featuring high density, low loss, and long-haul transmission suitability.
