Operating at 1550nm wavelength over 120km single-mode fiber, this 10G Base ZR+ module provides industry-leading distance performance. Supporting multi-rate transmission from 1. 32 Gbps, ideal for carrier backbone and ultra-long-haul applications requiring extreme reach. The 120km SFP optical module has emerged as a cornerstone technology for these requirements, enabling high-performance connectivity across significant geographic spans without the need for costly intermediate amplification or repeaters. Whether supporting metropolitan area networks (MANs) or remote. We offer both the DWDM-100G-Q28-120 and the DWDM2-100G-Q28-80, and we also frequently get a lot of questions regarding these modules, their differences, and their specifications. So we decided to compare both of these modules. In this article, you will find all of the right answers to your. All our SFP DWDM, 1. Every SFP-GE-DW-120KM module is environmentally tested in its specific port/platform, which includes compliance verification for distance, wavelength, traffic density and light. It uses fiber optical technology to send and receive data through completing the process of optical signal – electrical signal / electrical signal – optical signal conversion. An optical transceiver module consists of. Insert type SFP (miniGBIC) designed for transmission of double (duplex) single-mode fiber (SM) over a distance of 120km.
