Datasheet DWDM Multirate SFP Transceivers SFP27DWLR Features 100 GHz ITU DWDM grid - C-band standard - L-band by request 80 km, 120 km, and 200 km long reach DWDM SFP MSA compliance Cold start up wavelength compliance Low power dissipation (<1.3W maximum) -5º C to 70º C operating case temperature 100 Mbps to 2.7 Gbps multirate functionality SONET OC-48 /SDH STM-16 compliance Overview Standard SFP cage interface The DWDM Multirate SFP Transceivers from MRV provide flexible DWDM solutions in a compact package about six times smaller than the standard hot-plug MSA transceiver. Nearly any equipment with SFP ports can easily use CWDM wavelengths or the narrower DWDM channels with 100 Ghz spacing. Diagnostic performance monitoring of transmit power, receive power, laser bias, module temperature, laser temperature, APD bias voltage, and TEC current -28 dBm at OC-48 APD-based receiver sensitivity The traditional CWDM advantages include cost, simplicity, power consumption, and equipment density. The MRV DWDM multirate SFPs maximize scalability in both channel count and distance. C-band DWDM systems currently use 44 channels that can easily reach across metro networks with inexpensive erbium-doped fiber amplifiers (EDFA). These DWDM SFPs combine the best of all these features. General Operating Parameter Symbol Min. Typical Max.
