Pluggable multi-source agreement (SFP-MSA). As a two-way\noptical Transmitter receiver WDM uses TL-SM321B-2, has LC two-way connector\nintegrated Optical interface and data connection up to 2 km in 9\/125 µm SMF\n(single way fibre). TL-SM321B-2 also includes the function of digital\ndiagnostic monitoring (DDM), which is Compatible with SFF-8472. DDM supports\nreal-time transmitter receiver monitoring Time and display parameters\nincluding the transmitter receiver current that sends \/ optical power and\noperating temperature. TL-SM321B-2 of the TP connection is used in practice\nfor optical networks on it Short and medium distances and offer fast and\nstable gigabit optical Connections for switches, routers, servers and similar\ndevices. Key Benefits Accepts the last standard 1000Base-BX Transmission\ndistance up to 2 km in 9\/125 µm SMF (single - wise fibre). Compatible with\nthe small form pluggable multi-source agreement (SFP-MSA). Supports digital\ndiagnostic monitoring (DDM). Supports occupational exchange.
