Pulse touts SFP 1x10 Ethernet cage

AUGUST 19, 2008 -- The 10-port SFPCAGE006-L cage is used for connecting transceivers and shielding them from electromagnetic interference (EMI), say company representatives.

AUGUST 19, 2008 -- Pulse today introduced a 1x10 small form-factor pluggable (SFP) cage for use in Ethernet equipment such as blade servers, switches, routers, and add/drop multiplexers.

The SFPCAGE006-L cage is used for connecting transceivers and shielding them from electromagnetic interference (EMI).

Pulse says the device's high port density results in cost savings to the customer; the new cage is the first on the market with 10 ports, say company representatives. Prior to this 1x10 cage, the highest-density ganged SFP cage configuration was 1x6.

According to the company, its SFP cage is uniquely constructed so as not to deform during press fitting. The series can handle optical transceiver links as well as transceivers configured as traditional copper RJ45 connectors, enabling configuration to each company's internal networking requirements for balancing load and bandwidth. The cage has an insulation resistance of about 100 volts. Mylar paper pasted on the bottom isolates the cage and allows the customer to use the PCB under the cage for circuit trace design.

The cage handles speeds up to five gigabits and improves connectivity in high-density PCB environments, says the company. It reduces the operating temperature of the transceiver, prevents the transceiver from EMI emissions, provides mechanical stability, and offers easy transceiver plug-in. The cage is made of copper alloy with nickel plating to prevent oxidation. Holes in the cage allow air circulation and heat transfer, ensuring that the transceiver temperature stays at less than 70 ° Celsius. The cage measures 9.55- x 48.70- x 142.85-mm. The footprint is compliant with the SFP Transceiver MultiSource Agreement (MSA) standard and is RoHS compliant.

"Pulse has continued to expand its line of connectors and cages to improve the performance and reliability of the transceivers and thus the network they are connecting," reports Gerald Yang, product marketing manager of Pulse's Connector Division. "This 1x10 cage is a cost-effective, convenient, and reliable option for configuring an Ethernet network system."

Pulse's SFPCAGE006-L is available in tray packaging with prices around $13.00. Volume discounts are available.
