HM-RB006 is the compact and high-performance Gigabit Ethernet to STM-4 converter with VLAN TAG function, which provides three gigabit Ethernet interfaces (2xRJ45 and 1xSFP optical fiber Ethernet interfaces) and 2x STM-4 interfaces.

It adopt EoSDH technology and offer 1xVCG. The bandwidth can be configured from 1-8VC4. When in 2+0 mode, the 3xEthernet ports shares maximum 1112Mb/s(8xVC4).

• 1U 19inch
• Support automatic laser shutdown（ALS）
• Support remote power down detection(RPD）
• The two optical ports can be work with 1+1 redundancy.
