RJ45 1000BASE-T Copper Sfp Fiber Optic Transceiver Module
Description of Copper SFP Module
SPT-PTTX-RS1 Copper Small Form Pluggable (SFP) transceivers are
high performance, cost effective module compliant with the Gigabit
Ethernet and 1000BASE-T standards as specified in IEEE 802. 3-2002
and IEEE 802.3ab, which supporting 1000Mbps data- rate up to 100
meters reach over unshielded twisted-pair category 5 cables. The
module supports 1000 Mbps full duplex data-links with 5-level Pulse
Amplitude Modulation (PAM) signals. All four pairs in the cable are
used with symbol rate at 250Mbps on each pair. The module provides
standard serial ID information compliant with SFP MSA, which can be
accessed with address of A0h via the 2wire serial CMOS EEPROM
protocol. The physical IC can also be accessed via 2wire serial bus
at address ACh.
Features of Copper SFP Module

● Fully metallic enclosure for low EMI
● Low power dissipation (1.05 W typical)
● Compact RJ-45connector assembly
● Access to physical layer IC via 2-wire serial bus
● 1000 BASE-T operation in host systems with SERDES interface
● 10/100/1000Mbps compliant in host systems with SGMII interface
Applications
● Gigabit Ethernet over Cat 5 Cable
● Switch to Switch Interface
● Router/Server Interface

Mechanical Specifications
The host-side of the SPT-PTTX-RS1 conforms to the mechanical
specifications outlined in the SFP MSA1.The front portion of the
SFP (part extending beyond the face plate of the host) is larger to
accommodate the RJ-45 connector.
