Bel Fuse Inc., a premier developer of magnetic-based solutions
for high-speed networking and computer applications, today
announced the availability of the SFP-1GBT-03 transceiver module, a
Small Form-factor Pluggable (SFP) device offering Gigabit Ethernet
(GbE) speeds over Category 5/5e Unshielded Twisted-Pair (UTP)
copper cable. The module supports copper networks, with an
integrated SerDes PHY interface that can connect directly to a
fiber-optic module. Notably, Bel's SFP-1GBT-03 part operates at
610mW (typical in 1000BASE-T applications) and 320mW (typical in
10/100Base-T applications) for unsurpassed cost and performance
efficiency. It mates using a conventional RJ45 interface, and fits
into standard Multi-Source Agreement (MSA)-compliant SFP equipment.
Supporting both full-duplex and half-duplex communication, the
module complies with IEEE 802.3, 802.3u, and 802.3ab
specifications, and supports IEEE 802.3u and 802.3ab
auto-negotiation features allowing networking equipment to
automatically determine and adjust the required setting.
Bel's RoHS-compliant transceiver module is able to access the
physical layer IC (PHY) via I2C interface. Additionally, the device
features Baseline Wander correction to recover data in a worst-case
network environment, and an automatic medium-dependent interface
crossover (auto-MDIX) feature. In 1000BASE-T and 100BASE-TX modes,
the transmit data stream is scrambled to reduce radiated emissions
and to ensure that there is no correlation between symbols in the
data stream.
Supporting 10/100/1000 Mbps data-rate in excess of 100 meters
(325 feet) reach over UTP Category 5/5e cables, the robust
SFP-1GBT-03 transceiver module is ideally suited for implementing
small form-factor Network Interface Cards (NICs) and uplinks. As
such, it is highly appropriate for use in such high-density
applications as LAN 1000BASE-T, switch-to-switch interfaces,
switched backplanes, blade servers, gaming devices, and
router/server interfaces.
Lee Hancock, broadband product manager at Bel, said, "Bringing
the new SFP-1GBT-03 transceiver module to market is a significant
achievement for Bel, especially at this low price point. By
integrating Broadcom's BCM54616S Gigabit Ethernet transceiver, the
small form-factor module helps OEMs lower system cost and
substantially reduces power dissipation in applications enabling
high-speed, cost-effective network connectivity over copper cable.
We are pleased to be again working with Broadcom to develop
products of superior quality and functionality to help customers
expand their Ethernet applications."
"Broadcom's BCM54616S Gigabit Ethernet transceiver provides the
industry's lowers power and highest integration for maximum
flexibility in systems design," said Ravi Manik, product line
manager for Broadcom's PHY line of business. "Its integration into
Bel's SFP-1GBT-03 transceiver module is a logical solution that
will help enable a new class of cost-effective Gigabit Ethernet
SFPs."
Bel's hot-pluggable SFP-1GBT-03 transceiver module operates from
a single 3.3V power supply. It is packaged in a fully metallic
housing to ensure superior RFI performance and extremely low EMI
emissions to reduce the design constraints required to meet EMI
emission specifications. A bail latch facilitates ease of
extraction of RJ45 cable assemblies, even when transceiver modules
are closely ganged together in equipment racks. Operating case
temperature is 0 to +70 degrees C. For complete specifications
