SAN DIEGO, CA ‚– Pulse expands its line of connectors and cages with a 2×8, small-form-factor-pluggable (SFP) cage for use in high-end Ethernet networking equipment such as blade servers, switches, routers, and add/drop multiplexers. The SFP032-L cage is used for connecting transceivers and shielding them from electromagnetic interference (EMI). Its high port density results in cost savings for Pulse customers.
Several unique features of the SFP032-L cage eliminate frequently encountered problems. The cage has a two-piece structure to prevent deforming during press fitting. Press fitting force is applied only to the cage‚’s top section, while forces on either side of the cage are balanced so they will not twist or buckle. To prevent interference with the transceiver, the improved EMI tab rests on the cage so that the end does not sink into the cage when pressed. Pulse modified the cage with a special latch to accommodate a wide variety of transceivers and transceiver modifications, including those with short-travel actuating slides, which are commonly difficult to access to unlock and extract. Pulse also increased the slot depth of the middle cage, preventing interference with the middle cage transceiver, another common problem.
Pulse‚’s new 2×8 cage measures 25.5mm high x 63.25mm deep x 114.25mm wide. The footprint is compliant with the SFP Transceiver MultiSource Agreement (MSA) standard and is RoHS compliant. It handles speeds up to 5 gigabits and improves connectivity in high-density printed circuit board (PCB) environments. The cage reduces the operating temperature of the transceiver, protects the transceiver from EMI emissions, provides mechanical stability and offers easy transceiver plug-in. Holes in the cage allow air circulation and heat transfer. The cages can withstand temperatures of minus 40 to plus 85 degrees Celsius.
Pulse‚’s cages and connectors can handle optical transceiver links as well as transceivers configured as traditional copper RJ45 connectors, enabling conformity to each company’s internal networking requirements for balancing load and bandwidth.
Pulse‚’s SFP032-L cage is available in tray packaging with prices starting around $40.00 each. Volume discounts are available. Individual part pricing may vary due to order configuration and shipping destination. Lead time is six weeks. Contact Pulse directly for samples.
