Cielo announces 10 Gbps VCSEL-based 1310 nm serial transponder for OC-192 and 10 Gigabit Ethernet applications

June 21, 2001
June 21, 2001--Cielo Communications announced the release of what the company claims is the first 10 Gbps VCSEL-based 1310 nm serial transponder for high bandwidth optical interconnects.

Cielo Communications, an industry provider of Vertical Cavity Surface Emitting Laser (VCSEL) technology and integrated optical subsystems, announced the release of what the company claims is the first 10 Gbps VCSEL-based 1310 nm serial transponder for high bandwidth optical interconnects.

The transponder provides a reduction in cost, power consumption and board space to enable high-density 10-gigabit solutions and is the newest product in Cielo's platform of optical interconnects, which includes the 10 Gbps 850 nm serial transponder.

Cielo's compact 200-pin transponder features a jitter filter, high-speed serializer, laser driver and a 10 Gbps 1310 nm VCSEL on the transmit side, while the receiver incorporates a PIN photodiode, transimpedance amplifier, limiting amplifier, clock and data recovery (CDR) circuit, and deserializer to complete the module. The SC or LC pigtailed optical connections enable flexible positioning in tight layouts. The small, low profile footprint transponder provides customers with a significant reduction in board space and power dissipation when compared to current solutions. These features provide customers with a reliable, high performance solution for dense 10 Gbps optical interconnect applications.

The transponder is targeted at standards-compliant optical networking markets that include systems such as switches, routers, add/drop multiplexers and broadband interconnects. For added flexibility, the transponder feature a switchable bit-order function for operation in both Ethernet and SONET environments.

Cielo's optical transponder is designed to be fully compliant with the OIF-SF 4-01.0 implementation agreement for a common electrical interface between SONET framer and SerDes parts for OC-192 interfaces with versions that support OIF, Ethernet, SONET/SDH and Fibre Channel standards for 10 Gbps 1310 nm optical interconnects. The module is also compliant with the 200-pin Small Footprint OC-192 Transponder Multi-Source Agreement to enable rapid design-in for optical system developers.

Cielo's 10 Gbps 1310 nm Serial Transponder is priced at less than $8,000 in small volumes. The transponder will sample to development partners in Q3 2001.
