GLC-T 1.25 Gigabit Ethernet Sfp Module , 100m Copper Sfp Transceiver

Product Description
1.25Gb/s GLC-T 10/100/1000M Copper Ethernet SFP Transceiver 100m

Description
GLC-T10/100/1000 copper SFP transceiver is high performance, cost effective module
compliant with the Gigabit Ethernet and 10/100/1000BASE-T standards as specified in
IEEE 802. 3-2002 and IEEE 802.3ab, which supporting 10/100/1000Mbps data- rate up
to 100 meters reach over unshielded twisted-pair category 5 cable. The GLC-
T10/100/1000 supports 10/100/1000 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 GLC-T10/100/1000 provides standard serial
ID information compliant with SFP MSA, which can be accessed with address of A0h
via the 2-wire serial CMOS EEPROM protocol. The physical IC can also be accessed
via 2-wire serial bus at address ACh.
