What are the exact working wavelengths of the 12821 transceiver?

This module transmits data at a 1330nm wavelength (TX) and receives data at 1270nm (RX).

Do I need to deploy this BiDi SFP module in identical pairs on both ends of the link?

No, you must pair it with its complementary module (the 1270nm-TX/1330nm-RX model) on the other end to establish a working link.

What type of fiber optic patch cable should be used with the 12821 module?

It requires a single-mode fiber (SMF) patch cord with a simplex LC/UPC connector.

What is the maximum transmission distance supported by this 10G SFP+ module?

It reliably supports data transmission distances up to 20km over single-mode fiber.
