SFP-T1F-SATOP-I — SFP 1.544 Mbps

The SFP-T1F-SATOP-I is a Cisco SFP module dedicated to SAToP encapsulation (RFC 4553) for T1 circuits, delivering a data rate of 1.544 Mbps over Cat5e/Cat6A copper cable up to 200 m via an RJ-45 connector. Designed for T1 circuit pseudowire over IP/MPLS networks, it operates in an industrial temperature range of -40 to 85 °C, setting it apart from standard T1 interfaces for deployments in harsh conditions.

This transceiver suits Cisco gateways tasked with migrating legacy T1 access to modern packet networks without replacing end-user equipment. It addresses operators and enterprises maintaining T1 links in industrial or non-air-conditioned environments. Genuine Cisco hardware, manufacturer warranty.
