100BASE-T SFP Transceiver Module (Copper, 100m, RJ-45)
The HT201-03T 100BASE-T SFP transceiver supports up to 100m link lengths over a copper connection via a RJ-45 connector. Each SFP transceiver module is individually tested to be used on a series of FS switches, routers, servers, network interface card (NICs) etc. Featuring low Featuring low power consumption, the hot swappable 100BASE SFP transceiver is ideal for Internet Service Provider (ISP) Fast Ethernet communication links, Enterprise LAN & SAN Networks, Data Center LAN & SAN Networks and other optical links.

1. Copper SFP module DESCRIPTION
HT201-03T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the 100base-T copper SFP module standards as specified in IEEE Std 802.3. BDTR-FB-P1RC uses the SFP’s RX_LOS pin for link indication. If you pull up the SFP’s TX_DISABLE pin, the SWITCH IC will be reset.
2. PRODUCT FEATURES
l Support 10base-T / 100base-Tx

Notes:
-
Circuit ground is connected to chassis ground
-
PHY disabled on TDIS > 2.0V or open, enabled on TDIS< 0.8V
-
Should be pulled up with 4.7k – 10k Ohms on host board to a voltage between 2.0 V and 3.6 V. MOD_DEF(0) pulls line low to indicate module is plugged in.
-
LVTTL compatible with a maximum voltage of 2.5V.
