Model of Tanzanian optical module

Tanzania primarily imports optical modulator modules such as the Ficer XFP+LR 10G single-mode module and other SFP+ modules, used in DWDM and optical networking systems.Common Models and SpecificationsBased on recent import data, Tanzania has imported 55 shipments of optical modulator modules from July 2023 to June 2024, mainly from China, Vietnam, and India. Notable models include:Ficer XFP+LR Optical Module: Supports 10G speed, single-mode transmission up to 10 km, and is used in routers and optical networking devices. It comes with optical cables but typically does not include a transceiver or MMDS/ATTTM features .SFP+ 10G Single-Mode Modules: Operate at 1310 nm wavelength, capable of 10 km transmission, commonly used in DWDM systems and high-speed optical networks . Other imported devices include modules integrated into load balancing devices (Model TH1040S) and Fortinet firewall devices (Model FG-400F), which include optical modules for network connectivity but are not standalone transceivers .Performance in Tanzanian NetworksTanzanian optical networks, particularly DWDM systems, utilize these external modulator modules to achieve high data rates:2.5 Gb/s and 10 Gb/s transmission rates have been tested using external modulators, with receiver sensitivities of 30.5 dBm and 25.9 dBm, respectively, achieving a BER of 10^-12 .Dense Wavelength Division Multiplexing (DWDM) systems in Tanzania can support 40 channels with 100 Gb/s bandwidth, using EDFA and DCF to compensate for signal loss and dispersion over long distances .SummaryTanzania relies on imported optical modules, primarily Ficer XFP+LR 10G and SFP+ single-mode modules, for high-speed optical communication. These modules are essential for DWDM systems and other optical networking applications, supporting data rates up to 10 Gb/s and transmission distances up to 10 km. Their performance is enhanced with EDFA and DCF in long-haul networks to maintain signal integrity and low bit error rates .
