WDM 1.25 Gbps SFP Module Tx: 1310nm / Rx: 1550 nm - SM/LC Simplex, 20km

SignaMax Part No.: 065-79LX2WDMA1550

  • $ 461.50 or

The Signamax 065-79LX2WDMx1550 series models are Small Form-factor Pluggable (SFP) multimode fiber modules that support Gigabit Ethernet or SONET OC-12 over a single strand of singlemode fiber cable at distances up to 20 kilometers.

There are two types of models in this series: one transmits at 1310 nm and receives at 1550 nm (model 065-79LXnWDMA1550), and the other transmits at 1550 nm and receives at 1310 nm (model 065-79LXnWDMB1550).

These modules are designed to be used in pairs facing each other across a single stand of singlemode fiber.

The "n" in the part number refers to the first digit of the typical distance spanned in kilometers (2 = 20 km).

They are a cost-effective method of providing changeable Gigabit Ethernet or SONET OC-12 single-fiber singlemode interfaces to switches and media converters equipped with a standard SFP slot.
