This Industrial (Extreme Temp) Gigabit WDM (Single Fiber) SFP Fiber Module - Transmit/1310 nm - Receive/1550 nm - 10 km includes a temperature range of -40°F to 185°F

The Signamax 065-79LX1WDMx1550 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 10 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.  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 port.

Specifications:

** Maximum distances attainable on singlemode fiber circuits are dependent upon a circuit’s conditions; i.e., the number of splices and patch panels and the number of bends in the circuit path. For comparison with competing products, please use the Link Power Budget for meaningful comparisons.
