The Cisco SFP-OC3-LR1 is a Small Form-Factor Pluggable (SFP) transceiver module manufactured by Cisco Systems. It is designed for use in optical networking applications and specifically supports OC-3/STM-1 (Optical Carrier level 3/Synchronous Transport Module level 1) data rates. The "LR1" in the product name stands for "Long Reach 1," indicating that it is capable of transmitting data over long distances. The module operates at a wavelength of 1310nm and can transmit data up to a distance of 10 kilometers (6.2 miles) over single-mode fiber optic cables. It supports both single-mode and multimode fiber types. The Cisco SFP-OC3-LR1 is commonly used in networking equipment such as routers and switches to provide high-speed connectivity over optical networks.
