u2t Photonics pushes balanced detectors to 70GHz

  • u2t's 70GHz balanced detector supports 64Gbaud for test and measurement and R&D
  • The company's gallium arsenide modulator and next-generation receiver will enable 100 Gigabit long-haul in a CFP2

 

"The performance [of gallium arsenide] is very similar to the lithium niobate modulator"

Jens Fiedler,  u2t Photonics

Teraxion embraces silicon photonics for its products

Teraxion has become a silicon photonics player with the launch of its compact 40 and 100 Gigabit coherent receivers.

The Canadian optical component company has long been known for its fibre Bragg gratings and tunable dispersion compensation products. But for the last three years it has been developing expertise in silicon photonics and at the recent European Conference on Optical Communications (ECOC) exhibition it announced its first products based on the technology.

 

"You don't have this [fabless] model for indium phosphide or silica, while an ecosystem is developing around silicon photonics"

Martin Guy, Teraxion

Cisco Systems' 100 Gigabit spans metro to ultra long-haul 

Cisco Systems has demonstrated 100 Gigabit transmission over a 3,000km span. The coherent-based system uses a single carrier in a 50GHz channel to transmit at 100 Gigabit-per-second (Gbps). According to Cisco, no Raman amplification or signal regeneration is needed to achieve the 3,000km reach.

Feature: Beyond 100G - Part 2

 

"The days of a single modulation scheme on a part are probably going to come to an end in the next two to three years"

ECOC 2011: Products and market trends 

There were several noteworthy announcements at the European Conference on Optical Communications (ECOC) held in Geneva in September. Gazettabyte spoke to Finisar, Oclaro and Opnext about their ECOC product announcements and the associated trends.

 

100 Gig module

Opnext announced the first 100 Gigabit-per-second (Gbps) transponder at ECOC, a much anticipated industry development.

 

"Quite a few system vendors .... are looking at 'make-versus-buy' for the next-generation [of 100Gbps]."

Ross Saunders, Opnext
