The SFP-7020-WA is a Bi-Directional WDM A type, single strand fiber, Gigabit Ethernet SFP (Small Form Pluggable) 1.25G optical module. Transceiver is Cisco compatible and has DDM features.
It operates as WDM 1000BaseBX standard, covering a range of 20Km singlemode single strand fiber optical circuit. It can be used in any modern Ethernet switch equipped with SFP (miniGBIC) slots, as well as on any of the fiber optic media converters with SFP slot provided on eBay by sales_fo4all. The module is a B type WDM equipment using 1550nm wavelength for transmission and 1310nm wavelength for receiving data. It works in pair only with another WDM A type equipment (Tx:1310nm/Rx:1550nm).
The optical
module has been tested and found 100% compatible with various Ethernet
switches from major manufacturers like: Cisco, Nortel, Extreme, ZyXEL,
D-Link or Netgear.

!! Note: One WDM module operates in pair with a complementary WDM module only. WDM modules are A and B type. This item is WDM A type and works only with another WDM B type equipment at the other end of the single strand fiber. The other equipment is not necessary from same series or same SFP type, it can be a GBIC module or built in WDM B transceiver module, but it MUST be a B type equipment.
