The Transition Networks TN-CWDM-SFP-1xx0 and TN-CWDM-100LX-1xx0 small form factor pluggables (SFPs) are Cisco Compatible and are designed for bi-directional serial optical data communications such as Gigabit Ethernet, or Fibre Channel 1x. Each SFP operates at a nominal CWDM wavelength. There are 18 wavelengths available in 20nm steps from 1270nm to 1610nm.Transition Networks’ SFP modules fully comply with the Multi-Sourcing Agreement (MSA). This compliance allows our SFP modules to be used in all other MSA compliant SFP platforms. In addition, TN-CWDM-SFP-1xx0 modules are also compatible with all Cisco SFP-based equipment, as well as Cisco’s IOS software. TN SFP modules ARE NOT Cisco OEM brand modules.- Course Wavelength Division Multiplexing (CWDM) ITU Grid Compliant Wavelengths- Hot-Pluggable SFP Optical Transceiver With Duplex LC Connector- Digital Diagnostic Function (DMI)- Class 1 Laser International Safety Standard IEC-60825 Compliant- Compatible with SFP Multi-Sourcing Agreement (MSA)Applications:- Gigabit Ethernet Switches and Routers- Fibre Channel Switch Infrastructure- XDSL APllications- Metro Edge SwitchingAdditional Features:- Single +3.3 V Power Supply- Compliant with IEEE 802.3z 1000BASE-LX/ZX- Compliant with Fiber Channel 1x SM-LC-L FC-PI- RoHS Compliant
