1Gbps Cisco GLC-T Compatible 1000BASE-T SFP Transceiver – Cat5/6/7 – RJ-45 30m
The PDT-SFP-01-1G-0010 is a high performance Small Form Pluggable (SFP) transceiver which is compliant with Gigabit Ethernet and 1000 BASE-T standards to allow data transfer using CAT 5 UTP cable over a distance of up to 100m.
This device is compatible with most vendors including Cisco, Parallax Digital Technologies, Meraki, D-Link, Ubiquiti, Supermicro, Netgear, Broadcom, Mikrotik, Robustel.
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 at 250Mbps for each pair.
The modules provides standard serial ID information which can be accessed at address A0h via the 2 wire serial CMOS EEPROM protocol.
The physical IC can also be accessed via 2 wire serial bus at address ACh. The device is ideal for creating trunking links with typical CAT 5 cable where it is not possible or practical to install fibre optic cables

Notes:
Plug Seq.: Pin engagement sequence during hot plugging.
1) TX Fault is not supported and is always connected to ground.
2) TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7 ¨C 10 K resistor. Its states are:
– Low (0 to 0.8V): Transmitter on
– (>0.8, < 2.0V): Undefined
– High (2.0 to 3.465V): Transmitter Disabled Open: Transmitter Disabled
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K to 10K resistor on the host board. The pull-up voltage shall be VccT or VccR
– Mod-Def 0 is grounded by the module to indicate that the module is present Mod-Def 1 is the clock line of two wire serial interface for serial ID
– Mod-Def 2 is the data line of two wire serial interface for serial ID
4) LOS is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor. Pull up voltage between 2.0V and Vcc+0.3V. Logic 1 indicates loss of signal; Logic 0 indicates normal operation. In the low state, the output will be pulled to less than 0.8V.
5) RD-/+: These are the differential receiver outputs. They are AC-coupled, differential lines with 100 differential termination inside the module.
6) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100 differential termination inside the module.
