Victor Vaisleib and Ariel Maislos founded Passave Technologies in January 2001 “to build advanced silicon solutions for wide deployment of broadband fiber-to-the-user access networks – economically.” Passave secured Series A funding from BRM Capital, Eurofund, Walden Israel, and Intel Capital as well as several private investors including Ray Stata, founder and Chairman of Analog Devices. Passave has secured $10 million to date and plans to seek $10 million in roughly 6-12 months. The company has 20 employees.

Passave is developing “low-cost, high performance chipsets for FTTH and Ethernet.” Its initial products will support Ethernet Passive Optical Networks (EPONs), one of the fiber access networks being promoted by the Ethernet in the First Mile Alliance (www.

The IEEE 802.3ah EFM Task Force ( is chartered with developing the IEEE EFM standard, which will incorporate three subscriber access network topologies and physical layers, including point-to-multi-point EPONs. Passave founder and president Ariel Maislos is the editor for the IEEE 802.3ah EPON track and Passave’s ICs will support the IEEE 802.3ah EFM standard.

According to Passave, FTTH is now a reality in the Asia/Pacific region. In Japan, with 400K FTTH subscribers today, deployment rates of 200K to 300K per month are reasonable within 24 months time frame, according to the company. And the US market is about twice as large as the Japanese market.

SBC, Verizon, and BellSouth recently announced that that have standardized on a FTTx technology backed by existing standards, which is presumably G.983 APON since that is the only currently fully ratified standard. While this could be seen as a setback for the EPON camp and Passave, the company believes “the surge of ILEC interest in FTTH and PON is excellent news.”

Passave believes EPON will ultimately be less expensive than ATM-based APON technology, which will drive the service provider decision process. As Passave puts it, “never bet against Ethernet.” NTT Japan’s early deployments utilized APON, while current and future deployments are focused on Ethernet. And Passave believes other service providers will follow suite, migrating to EPON as soon as the standard is ratified and EPON equipment is available.

Passave’s products are intended to facilitate rapid deployment of EPONs by reducing the cost and time-to-market for both the Optical Network Unit (ONU) at the customer premise and the Optical Line Terminal (OLT) at the central office.

The company recently introduced its first chip, the PAS6001 single-chip Gigabit EPON solution for low-complexity, low cost FTTH ONUs. Additional applications include FTTx, and IP backhaul for WLAN, remote DSLAMs, and cellular stations.

The PAS6001 is claimed to be the first device conforming to the emerging IEEE 802.3ah EFM standard. The PAS6001 features integrated security, Ethernet MAC functionality, EPON protocol management, OAM protocol, UNI, burst control, as well as bridging with IGMP filtering and traffic management functions. The device provides AES encryption for all subscriber traffic and authentication functions. It supports IP video using IP multicast and analog video overlay. It also supports TDM services using stratum clock recovery. The device achieves over 95% upstream utilization using dynamic bandwidth allocation.

The PAS6001 integrates all required buffer memories and is capable of standalone operation without an additional CPU. The device has been proven with burst optics from multiple vendors, and supports industrial temperature range for harsh environment use.

Passave focuses on end-to-end silicon solutions for EPONs and is also developing the PAS5001 OLT chip. The PAS6001 is available now and is fabricated in 0.18u CMOS by Samsung while the PAS5001 will be announced soon.

Competitors include austriamicrosystems and BroadLight, although BroadLight’s products currently do not focus on the EPON space. BroadLight is an APON vendor and also has transceiver offering. Passave’s primary competition at this point is internal R&D efforts within the large vendors.

Passave claims to be in the leader with working, demonstrable products for EPONs. Passave has also been selected to write the draft for the P2MP (Point-to-Multi-Point) EPON portion of the 802.3ah standard. Passave’s chipset is standards compliance with QoS and VLAN support. The company offers a reference design with a complete software suite, claims to have unique IP, and is completely focused on EPON.
