fiber ports over SFP 1.25Gb/s modules are hot

The 1000Base-T SFP copper module is compliant with Gigabit Ethernet and 1000BASE-T standards as specified in and IEEE 802.3ab for SFP 1.25Gb/s Gigabit over unshielded twisted-pair category-5 cable. It ofers full duplex data-links with 5-level Pulse Amplitude Modulation (PAM) signals. This transceiver is also compliant with RoHS, SFP MSA, FCC 47 SFR Part 15, Class B and SONET/SDH recommendations for OC-48 specifications. It is widely used in serial telecom and datacom applications. Cisco 1000BASE-T SFP modules support auto negotiation and Auto .SFP 1.25Gb/s can be regarded as the upgrade version GBIC. Unlike GBIC with SC fiber optic interfaces, cisco SFP is with LC interface. Moreover, its main body size of SFP is only about half of GBIC, which makes SFP space saving. Cisco pluggable transceivers offer a convenient and cost effective solution for the adoption in data centers, campuses, metropolitan area access and ring networks, and storage area networks. Users can replace a single SFP module during the process instead of replace the whole board with many modules on it.
