The OH-BD-10G-1270-LC is a 10 Gbit/s bidirectional optical transceiver. The TX wavelength is 1270 nm and suitable for distances up to 20km**. The RX wavelength is between 1320 nm and 1340 nm.

This SFP is typically used in simple WDM closed loop point to point applications and is intended to be paired with the OH-BD-10G-1330-LC SFP at the other end of the fiber link.
