10 Gbit transponder and protocol converter
The PM 1001 10 Gbit LAN PHY to WAN PHY protocol converter connects 10-Gbit LAN switches to 10 Gbit SONET/SDH and DWDM networks. The PM Series is a multiservice platform that allows carriers to aggregate and transport high-speed services onto a single wavelength at wire speed over 10 or 2.5 Gbit signals. This TDM-based aggregation reduces the number of wavelengths on the network, lowering the cost of deploying DWDM or CWDM networks. The PM1001 is also a DWDM transponder for any 10 Gbit protocol ranging from 9.95 to 10.709 Gbit/s. Embedded forward error correction allows it to transport 10 Gbit data over longer distances without repeaters.
With a totally modular and customisable design, the CT-400 residential gateway series supports gigabit passive optical network (GPON) and Ethernet PON (EPON) fibre deployment standards. Options for VDSL 2 can be incorporated in conventional DSL copper wire situations. Inside the home, MOCA, Powerline, and MPNA V3 home networking interfaces will be supported in the future. The CT-400 includes Gigabit Media Interface (GMI) buses that enable high-speed connection between the WAN module and the device’s Gigabit Ethernet (GbE) switch. Up to five GbE LAN interfaces can be accommodated. The unit also supports a GbE WAN interface, enabling it to be connected to an unintelligent Network Interface Device (optical bridge) on the house side using GbE copper wire.
The SmartAX OFA5920 GPON system provides up to 1 Tbit switching capacity. It complies with ITU-T G984.1/2/3/4 standards and is the industry’s first GPON access platform with terabit nonblocking switching capability and full redundancy design. The system provides users with reliable voice, data, and video services at downlink and uplink rates up to 2.5 Gbit/s and 1.25 Gbit/s, respectively.

The CM-104 is a compact, fully redundant, and modular packet transport switch (PTS). It supports 10 or 2.5 Gbit/s network-side interfaces and is based on MPLS, RPR, and SONET/SDH for carrier-class packet transport. The CM-21 PTS provides Ethernet access for residential and business customers. The CM-21 provides 24 Gbit/s of nonblocking switching capacity, making it suitable for bandwidth-intensive and interactive applications such as IPTV, voice over IP, and video-on-demand. The CM-21 product line comes in four different configurations, all in a single rack unit, supporting optical or electrical Fast Ethernet and Gigabit Ethernet interfaces, including redundant AC and DC power options.
DWDM XFP transceivers
A family of DWDM XFP optical transceivers offers modules with high output power and a wide range of dispersion-tolerance levels for distances from 80 to more than 200 km. This range allows customers to optimise the cost-performance ratio across different networks, including metro and regional. The RoHS-compliant transceivers are designed to help reduce multichannel WDM system inventory and minimise dispersion management complexity and cost.

The Free-Path Manageable Dispersion Compensation Module (M-DCM), a manageable dispersion-compensating fibre (DCF) replacement, is designed for metro-regional DWDM networks across the entire C-band. The etalon-based M-DCM is used to compensate for chromatic dispersion values ranging from -1,700 ps/nm to +1,700 ps/nm, using in-house intellectual properties. The multichannel module reduces in-line amplification requirements and allows remote management of dispersion while using a single part number as a substitute to multiple DCF part numbers.
A new 40-channel reconfigurable optical add/drop multiplexer (ROADM) module with per-channel variable optical attenuators and power monitoring allows any wavelength to be dropped or added at any node in a DWDM network. PLC integration increases performance at a competitive cost. The low-power, high-isolation broadband PLC Switch-VOA-Tap (SVT) design enables a higher level of single-chip integration, significantly reducing power consumption, size, and cost of the module.
The Sentior 27000 East/West VG erbium-doped fibre amplifier (EDFA) comprises two independent variable gain stages, which allow the deployment of the amplifier in systems supporting East/West separation. This configuration avoids a single point of failure that could affect both the normal and protection data paths, resulting in a critical system failure. The 27000 can also be configured to work as two completely independent single-stage VG amplifiers, so that two single-stage VG amplifiers can be packaged into one module, decreasing cost and space consumed.

A line of optical protection switch (OPS) plug-in modules for the PowerNode platform is used for fibre link, equipment, or client side protection. The modules have switching speeds of 10 ms, which allows sub-SONET/SDH optical protection. The OPS product line is designed for both system OEM and carrier customers. An OPS module monitors the optical power on incoming fibres. Upon detection of faults, the module toggles the bypass switch to activate the protection path within 10 ms. Using standard SNMP or TL1 interfaces, the plug-and-play OPS can be directly deployed and managed as a standalone network element within an optical network node.
An eight-port tributary adapter module (TAM) for the DTN platform offers greater capacity and density for Gigabit Ethernet (GbE) and supports full performance monitoring capability. The DTN can now deliver up to 320 GbE ports, along with all supporting WDM line-side equipment, in a single bay, resulting in a high-density core DWDM transport system. A multirate capability for the 2.5 Gbit TAM module gives customers the flexibility to configure the software for each optical port interface on the module to support transparent OC-3/STM-1, OC-12/STM-4, or OC-48/STM-16 service. The multirate capability provides a cost-effective option for carriers offering both low- and high-speed services.
GPON and GEPON chipsets
Following the release of the PHY1078 GEPON chipset, the PHY2078 transceiver IC is designed for the higher-bandwidth 2.5 Gbit/s GPON ITU G.984.2 standard. It can be combined with a microcontroller to support digital diagnostic monitoring (DDM). The PHY1095 and PHY1097 transimpedance amplifiers are capable of high-sensitivity performance without the added cost of an avalanche photodiode circuit. The PHY1097 is designed for GEPON and GPON operating at up to 2.5 Gbit/s, with sensitivity of -29 dBm and low input referred noise of 150 nA. The PHY1095, which operates at up to 1.25 Gbit/s, servicing the GEPON sector of the market, achieves -32-dBm sensitivity coupled with 60 nA of input referred noise.
