PORTFOLIOS WE COVER
Packet-Optical Access
A new class of network equipment that integrates packet switching with optical transport in the access network is appearing in the marketplace. Current Analysis is calling this product class Packet-Optical Access – POA. A POA device is similar to the metro’s packet-optical transport system (P-OTS), but it is of a smaller scale and is used for access/aggregation rather than metro office interconnection.
POA devices are well-positioned to address the mobile backhaul market, especially 4G backhaul, and because of the rapid growth of this application, POA devices currently appear to be used primarily for backhaul. However, as POA devices are deployed throughout the access network, operators will likely begin to consolidate their access networks onto these devices, calling on them to serve many connections beyond the T1/E1 and Ethernet connections of mobile backhaul.
Product Assessment reports from Current Analysis provide a timely and in-depth evaluation on how leading products and services in a market measure up to their competition. Updated regularly by our industry-leading analysts, the reports deliver an objective and un-biased look at a product's strengths and weaknesses, ratings on how well the product meets specific customer buying criteria, and relevant product metrics. Compare selected products with side-by-side listings of product metrics and other factors, with a focus on actionable intelligence.

| AVAILABLE PRODUCT ASSESSMENTS |
 |
ADTRAN Total Access 5006 |
|
| ADTRAN enhances its TA 5006 MSAP with optical networking capabilities to provide a POA platform with legacy and packet networking capabilities, several uplink protocol options and low power consumption, but a limited IP/optical integration story. (5/4/2012) |
| | Client Access | |
 |
Alcatel-Lucent 1850 TSS-5c and TSS-5R |
|
| Alcatel-Lucent’s 1850 TSS-5c/5R provide both POA functions in small, low-power packages with a capable/flexible NMS, but lack of SONET/SDH limits their use in legacy networks, and modest packet capacity may limit support of next-gen services. (5/7/2012) |
| | Client Access | |
 |
Cisco CPT 200 |
|
| Cisco has added PDH interfaces and SONET/SDH capabilities, seamless switch/router interoperability, high port and switch capacity and PRIME management suite of its CPT 200, but the product’s uplink capacity is still modest. (5/7/2012) |
| | Client Access | |
|
ECI Telecom OPT 9604 and OPT 9608 |
|
| ECI introduces the OPT 9604/9608 as a packet-optical access device that provides high uplink and port capacities, various protection methods, and rich networking capabilities, but it does not offer PDH connections or SONET/SDH ADM. (5/7/2012) |
| | Client Access | |
|
Ericsson SPO 1410 |
|
| Ericsson’s SPO 1410 takes a leading spot in the POA market by serving the two POA roles while offering rich Ethernet and MPLS features, high port density and varied uplink options, but lack of SONET capability could slow North American traction. (5/7/2012) |
| | Client Access | |
|
Fujitsu FLASHWAVE CDS |
|
| Fujitsu’s FLASHWAVE CDS extends the packet and TDM networking of its P-OTS platform into the access network, providing numerous packet and TDM ports and consuming little power, but offering no PDH ports and a limited IP/optical integration story. (5/4/2012) |
| | Client Access | |
|
Tellabs 7100 Nano OTS |
|
| Tellabs employs the compact version of its 7100 OTS, the Nano, as a POA product with high port density, high switching and uplink capacities and an ASON control plane, but without PDH support and awaiting MPLS and IEEE 1588v2 support. (5/4/2012) |
| | Client Access | |
|
Transmode TM-301 |
|
| Transmode’s TM-301 packet-optical access product provides high packet and uplink capacity, SONET/SDH and PDH networking capability, and low power consumption, but it lags in router/switch integration and TDM switch capacity. (5/7/2012) |

Packet-Optical Access Buying Criteria
- Data Application and Protocol Support
- How will this platform support the packet connection services that will run it? Ethernet protocols that are considered “table-stakes” for this class are 802.1D MAC Bridging, 802.1Q VLAN, 802.1ad QinQ, 802.3ad/802.1AX LAG, 802.1s/802.1w MSTP/RSTP, 802.1p QoS, 802.3ah EFM and 802.1ag/Y.1731 OAM.
- Number and Type of Client Interfaces
- How many of each type of client interface are supported on the platform? Does not include uplink interfaces. PDH interfaces are T1/E1 and T3/E3 ports. “Other Interfaces” include SAN and digital video ports.
- Platform Capacity – TDM, Packet and Uplink
- Switching and transport capacities of the platform. Packet capacity is expressed in non-blocking full-duplex Gbps. TDM matrix size is expressed in Low and High Order cross-connect capacity. Uplink capacity is the maximum protected traffic offered by device to core of the network, full duplex.
- Optical and Layer-1 Transport Features
- These are the overall transport features of the platform, including uplink protocols offered, protection, optical networking and layer 1 features. The criterion also addresses the vendor’s metro/core network elements with which the platform could connect.
- Physical Attributes and Management
- Physical attributes include chassis size (in Rack Units), number of interface slots and dimensions. Certifications include NEBS, OSMINE, UL and outside plant hardening. Other Elements Managed is a listing of the vendor’s other products that are managed under this same network management system.
