Key benefits: ● Optimized for datacenter/SAN interconnects and Mobile Fronthaul thanks to broad support for services such as FC, 10GbE and CPRI/OBSAI

● Unprecedented high density capabilities with 6 transponder functions on a one slot unit saving valuable rack space

● Wide range of supported traffic formats using SFP and SFP+ transceivers (614Mb/s – 14Gb/s)

● Technology agnostic. Pluggable transceivers enable usage in CWDM as well as DWDM networks

● Low latency making this unit ideal in datacenter and Mobile Fronthaul applications

● Low power consumption reducing the total cost of ownership

The HEX Multi-Rate 16G Lite Transponder (TPMRHEX-L/16G) is part of Transmode’s TM-Series packet-optical platform. The TPMRHEX-L/16G is a 1-slot unit providing six independent transponder functions. This enables the unit to provide extremely dense and energy-efficient 40/80 channel networking solutions.

The TPMRHEX-L/16G is characterized by high density, low latency and low power capabilities as well as multi-rate support. These are advantages that make the TPMRHEX-L/16G specifically suitable for applications such as datacenter/SAN interconnects and mobile backhaul/fronthaul. The unit is also useful in generic applications providing cost-efficient 10Gb/s transport.

Multi-Rate support for multiple services

The TPMRHEX-L/16G’s interfaces support both SFP and SFP+ transceivers which provides a provides an extremely wide range of supported signal formats.

Each transponder function is transparent (i.e. without any digital wrapper) and supports bit rates between 614Mb/s (CPRI/OBSAI) and 14.025Gb/s (16G FC).

Six independent transponder functions in only one slot

Each transponder function performs 3R regeneration (Re-amplify, Re-shape, Re-time) regardless of traffic format.

The transparent 3R functionality enables the TPMRHEX-L/16G to be used as a transponder or a regenerator for any signal format.

Regeneration of FEC coded signals, such as OTU2, can be done without affecting the performance of the link since the end points’ FEC coding is sufficient.

Each transponder supports near-end as well as far-end loopback configurations for fault finding purposes.

Management interconnect without local DCN access

A patent pending out-of-band management channel solution enables management interconnect, signaling and software download without the need for local DCN access. This provides a smooth solution to management interconnect as no digital wrapper based dedicated management channels exists.

Client/equipment protection

Two transponders functions can be connected via an optical coupler into a client/equipment protection configuration. There are three options for this protection mechanism: a) between two transponder functions located on the same unit, b) between two transponders located on two different units within the same card cage, or c) between units located in separate chassis via the Protection Control Unit (PCU/2P).

Ideal in Mobile Fronthaul applications

The TPMRHEX-L/16G supports all CPRI/OBSAI rates from 614Mb/s up to 10.1376Gb/s with lowest possible latency. This makes the TPMRHEX-L/16G ideal in Mobile Fronthaul applications.

mounted in the rack while the active transponder and amplifier units (if required) are located in the chassis. All 80 transponder functions fit into a single chassis with about 450W card cage power consumption.

Low power consumption

A TPMRHEX-L/16G fully equipped with SFP+ transceivers in all ports consumes less than 30W. Low power consumption in combination with a high density reduces site costs and enables more capacity to be handled at sites with restrictions on power consumption, cooling and space.

High Density multi-service application example

A complete 40 channel multiservice system can be configured within a single TM-3000/II or TM-3000 chassis as shown in the figure below.

Fig 1. A high density and complete 40 channel system within a single TM-3000/II chassis.

The configuration includes optical interleavers to enable hit-less expansion to 80 channels. Automatic power balancing is provided via an Optical Control Loop between the Optical Channel Monitoring unit (OCM/2P) and the VOA-functions within the 40ch MDU unit. The configuration also includes pre-amplifier and booster amplifier as well as Optical Supervisory (OSC) channels. The chassis configuration shows that there are still unused slots in the chassis. The total card cage power consumption for this configuration is about 300W.

High Density Data Center Interconnect example

For one-hop applications where automatic power balancing is not needed, an even denser configuration can be achieved by using the 40ch MDU units from the TG-Series. These filters are then
