LambdaDriver® E8GM modules use advanced Time Division Multiplexing (TDM) technology for combining and simultaneously transporting 8 E1/T1 circuits and one GE port over one Full Duplex fiber optic trunk to different distances. The modules are transparent to framing format, and support HDB3 and AMI line codes and interfaces complying with ITU-T G.703 instructions. There are different options for aggregated trunk port:
• SFP based modules (EM2009-E8GM/ EM2009-T8GM). The aggregated trunk speed is 1Gbps and therefore this module can use regular GE SFPs that can provide distances up to 120Km without repetition or even CWDM SFP’s to allow higher service aggregation over single fiber.
• Fixed CWDM/DWDM optical interface (TM-E8GMC/xx or TM-E8GMD/xx). This module allows mixing E1/T1 services with other traditional services running together over WDM network.Optional RS232 channel is multiplexed together with 8 x E1/T1 + GE services provides excellent opportunity to pass control or even management (CLI) signal over the same wavelength. The data speed of RS232 is factory pre-configured for 9.6Kbps, but can be different per special request.In conjunction with the LambdaDriver Element Management Module, full monitoring and confi guration capabilities become available locally at a craft terminal via the RS-232 interface and remotely at a TELNET or SNMP station via an Ethernet/Fast Ethernet interface. MRV’s MegaVision Web-based SNMP management application provides remote control reducing the costly need for many in-the-field services.The modules fully support Digital Diagnostics provided by SFP’s per Multi-Source Agreement (SFF-8472),including Optical Transmit Power, Optical Receive Power and Temperature Measurements. The modules are hot swappable and fit into any LambdaDriver chassis.
