The SDH04A is a compact NG-SDH equipment which supports STM-1/4 ADM and offers various tributary interfaces like E1/T1, V.35,

FE/GbE, E3/ T3…etc to provide any service in any slot. SDH04A is suitable for the applications of GSM/UMTS base station radio access

networks (RAN) / MSAN and wireless backhaul. The SFP cage design in SDH04A offers the plug-and-play flexibility to change fiber modules

for different bit rate and higher availability to use off-the-shelf fiber modules . Although SDH04A is a 1U standard form factor makes CTC

SDH04A easy to fit in any 19” or 23” chassis and outdoor cabinet; Although SDH04A is a compact NG-SDH box, it also has similar flexibility

of shelf-type SDH equipment, such as hot-swappable tributary cards / fiber modules / power modules and 1+1 load-sharing redundant power

design. In order to supply reliable networks to carry more upcoming broadband services from wireless / HSDPA base stations to central

office, CTC SDH04A provides carry-grade Ethernet (E-Line) bundled with L2 functions to totally control QoS between end to end. SDH04A

also can work with CTC SDH01A series to have Ethernet private LAN (E-LAN) service in ring topology.
