Fiber Arsenal SFP WDM, 1.25Gbps, LC simp., 20km, 1550/1310nm, DDM,-40°C to +85°C, Cisco

It is a compact optical transceiver from the Fiber Arsenal EXTERNALS used in telecommunications and data networks. It is popular, widespread, manufacturers of active optical components massively supported module
Special WDM modules are used for two-way operations that work on the principle of different broadcast wavelengths (always in pair type A and type B) and have already built-in WDM filter.
