L-com has added two lightning and surge protectors for telecommunications equipment to its line of products. The HGLN-CAT5J is fully compatible with industry-standard 802.3af Power-over-Ethernet (PoE) devices and 10/100 BaseT Ethernet networks, protecting both Ethernet data pairs as well as the PoE dc power feed. It supports modes A and B of the 802.3af standard for supplying dc power. The AL-D4W-DP protects DSL and telephone lines from transients or surges caused by lightning strikes. Like the HGLN-CAT5J, it uses thyristor diode technology, which L-com says offers superior power-handling capability compared to designs based on transient voltage suppressor (TVS) or Zener diodes. It will protect up to four signal pairs.
