Demands on access networks are increasing at an accelerating rate, requiring a clean-sheet approach to a truly scalable multi-service architecture. Zhone’s MXK™ intelligent terabit access concentrator reflects this new approach, with non-blocking capacity of up to 3,600 100Mbps GPON subscribers or 360 1G Active Ethernet subscribers per chassis. Beyond sheer bandwidth, MXK platforms leverage Zhone’s well-proven SLMS access operating system for sophisticated service intelligence, to guarantee high quality of experience for subscribers, along with ease of management to address rising costs of network operation.

The MXK delivers these fundamental advances in access networking while meeting the full spectrum of baseline carrier-class requirements for multi-service hardware and software. For residential triple play and high-bandwidth business services over any FTTx architecture, the MXK solution sets a new performance benchmark for the industry.

The MXK family offers a wide range of options for FTTx solutions. It supports Active Ethernet and GPON line cards, and interoperates with indoor and outdoor ONTs. Supporting Active Ethernet and GPON on the same chassis allows service providers to configure their networks with maximum flexibility and efficiency, using a combination of GPON splitters and dedicated fiber connections.

MXK Chassis
The MXK family includes three fully-integrated form factors: 319 (19″ rack x 3RU, with 7 slots for line cards), 819 (19″ rack x 8RU, with 14 slots for line cards), and 823 (23″ rack x 8RU, with 18 slots for line cards). The chassis support both front and rear power options and are equipped with a cable management tray, easy fan access, and redundant power feeds.

MXK Uplink Cards
MXK uplink cards offer a mix of multiple 10G and 1G interfaces to suit a variety of network designs. Several line rate configurations are currently available, including two different variants of 2x10G + 8x1G, as well as 6X1G. These cards provide connection points for common synchronization inputs including SyncE and 1588v2, as well as support for both copper and fiber SFPs, link aggregation, link redundancy, and the EAPS ring interface.

MXK Line Cards
The MXK platform supports GPON and Active Ethernet line cards for FTTX applications as well as seamless, same-chassis support of MSAN services including ADSL2+, VDSL2, G.SHDSL EFM, POTS, and T1/E1 PWE. The 4- and 8-port GPON OLT line cards provide standards-based support of 2.5Gbps downstream and 1.25 Gbps upstream bandwidth. The largest MXK chassis can support up to 9,216 ONTs using Class B+ or C optics. The Active Ethernet line cards provide up to 360 ports per chassis of 100/1000BT copper or 100/1000Mb fiber-based services. Operators can use a wide variety of SFPs on the same card.
