Rochester, N.Y.-based Fibertech Networks has increased its senior debt by $30 million to back acquisitions and support capital expenditures, according to sources. Half of the $30 million has been layered into an existing $37.5 million, five-year revolver, which now totals $52.5 million, with the rest added to a $235 million, six-year term loan, now $250 million, sources said.

The new money was layered in at existing pricing of L+450 on the RC, and L+500 on the term loan. Both tranches are subject to a 1.75% LIBOR floor.

Incumbent arranger TD Securities led the transaction, which has closed and funded.

Fibertech is rated B/B2 by agencies.

The company provides fiber-optic-based network services throughout midsize cities in the Eastern and Central regions of the United States.
