Calix E7-2 GPON-8 Card EXA

The Calix E7-2 GPON-8 line card provides eight ITU G.984-compliant Gigabit Passive Optical Network (GPON) interfaces, four Gigabit Ethernet (GE) interfaces, and two ports of integrated 10-Gigabit Ethernet. The E7-2 GPON-8 line card can be plugged into one or both of the two universal slots in a Calix E7-2 shelf. In a 1RU chassis, E7-2 supports sixteen PONs, up to 64 Optical Network Terminations (ONTs) for a total of 1024, plus eight point-to-point Ethernet subscribers and two 10GE ports. The E7-2 GPON-8 card supports a full set of Ethernet services and network topology protocols on the Ethernet ports and can be used interchangeably with other E7-2 line cards to create a redundant system configuration.

GPON and Point-to-Point Ethernet:

The Calix E7-2 GPON-8 card provides multiservice capability over IP/Ethernet-based networks. Each GPON-8 provides eight GPON OLT ports that subtend up to 64 ONTs each, for a card capacity of 512 GPON ONTs, 1024 per E7-2 1RU chassis. Additional four GE ports per card can provide high-bandwidth, point-to-point Ethernet services to individual subscribers or be used to aggregate other Ethernet devices.

Multiple E7-2 shelves can be linked together using low cost, industry standard 10GE SFP+ copper cables, resulting in a high-density configuration serving over 1000 GPON ONT subscribers in as little as 1RU space (1:64 split). GPON-8 card features and capabilities include:

• Based on ITU G.984 GPON family of standards—including G.988
• GPON: 2.488 Gbps downstream, 1.244 Gbps upstream
• GEM (Ethernet) based GPON
• Interoperable with Calix ONTs, including the GigaFamily
• Integrated 10GE and GE/2.5GE aggregation and transport
• Class B+ ODN, +28 dB link budget, up to 20 km at 32-way splits
• Extended reach GPON up to 40 km with 1:8 split
• Class C+ ODN, +32 dB link budget with Forward Error Correction (FEC), up to 35 km at 32-way split, up to 60 km at 2-way split
• Hardened for central office and remote terminals

Integrated High-Capacity Aggregation:

The E7-2 GPON-8 card is built on a core Layer 2 and Layer 3 switch capable of full-duplex, line rate forwarding at all frame sizes and traffic types across all interfaces. Each GPON OLT port has a dedicated 2.5Gbps switch interface. Industry standard pluggable modules are used for all interfaces, including ITU G.984 compliant GPON, GE and 2.5GE optical SFP, and 10GE SFP+. The SFP+ ports also support SFP modules and Direct Attach copper cables.
