» NFC Wrap: East | West | North | South » AFC: East | West | North | South » Grades With free agency and the draft in the rearview mirror and training camp just a couple of months away Jim Rice Jersey , we assess the Buffalo Bills' offseason moves.Best move: Signing linebacker Brandon Spikes to a one-year, $3.25 million deal was easily their best move of free agency. While former defensive coordinator Mike Pettine's group set a franchise sacks record last season and was near the top of the league in several pass-defense statistics, the run defense was suspect at points. Spikes has question marks as a pass-defender -- or else he would have commanded a more lucrative long-term deal on the open market -- but there is little doubt about his abilities as a run-stuffer. If he can stay healthy, he and Kiko Alonso should make a formidable duo at linebacker.[+] EnlargeAP PhotoBill WippertFirst-round pick Sammy Watkins gives the Bills' offense another home-run threat.Riskiest move: If we're viewing risk through a long-term lens Jimmie Foxx Jersey , it has to be the Bills' decision to give up a 2015 first-round pick to acquire Sammy Watkins. That's a trade that can define the tenure of a general manager. But viewing risk simply in the context of this season, trading Stevie Johnson presents an element of uncertainty. Johnson missed four games with injuries last season and might have been a higher-maintenance player for the coaching staff, but his production from 2010 to 2012 -- more than 75 catches and 1,000 yards each season -- is hard to give up. Johnson is 27 and still in the prime of his career. Having Watkins lessens the need for Johnson Hanley Ramirez Jersey , but it's tough to argue that dealing Johnson has made the Bills better.Most surprising move: This move wasn't necessarily surprising for the Bills, but tight end Scott Chandler was likely hoping to earn more on the open market than he got by returning to the Bills. Chandler came back to Buffalo on a two-year deal that pays him less than his previous contract. Given that Chandler is 28 and coming off a season in which he set career highs with 53 catches and 655 yards, that's a surprise. The Bills are hoping that Tony Moeaki can return to his previous form, but if he doesn't Fred Lynn Jersey , Chandler should be the opening day starter at tight end. It's a position the team will likely address in the draft next season.Are they better? After all of their moves this offseason, are the Bills markedly better than they were when they walked off the field after their last game in December? I don't think the answer is unequivocally "yes." On the plus side, Watkins should be an upgrade over Johnson, while the Bills are deeper at running back and cornerback. On the down side Dustin Pedroia Jersey , they have question marks at safety after losing Jairus Byrd and it has yet to be seen how players like defensive end Jerry Hughes, who excelled in Pettine's scheme, will fare in Jim Schwartz's system. A big second-year jump from quarterback EJ Manuel would overshadow any potential issues elsewhere, but this team still has a lot to prove on the field before the offseason can be considered a success.The two most common outdoor fiber optic cable installations are pole line aerial installation and underground cable installation. Underground cable installation can be buried directly underground or placed into a buried duct.Direct burial installation:Direct burial installations are most common for long cross-country installations. The cables are plowed in or buried in a trench; the installation process can be very quick. The most common cables used for direct burial are steel armored outdoor fiber cables.Underground duct installation:Fiber optic cables can also be pulled through underground ducts David Price Jersey , which protect the cables from harsh environment. Underground duct installation also provides opportunity for future expansion without the need to dig. This is the most common practice in urban areas. Another benefit is that fiber cables without armor can be used which makes the installation even easier.Preparation before underground cable installation:1. Obtain proper right-of-way permits2. Identify existing underground utilities such as buried cables, pipes3. Investigate the soil condition in order to determine the installation depth, whether duct should be used, the type of fiber cable should be used and plowing equipment neededCable Burial techniques:1. Plowed underPlowing in a fiber cable is faster than trenched. But this process has to be carefully monitored to prevent from damaging the cable.2. TrenchedThe fiber cable can also be trenched. This process is slower than plowing in; however David Ortiz Jersey , it allows a much more controlled cable installation. Trenches can be dug by hand or by machine.3. Directional boringDirectional boring technique is used where the surface cannot be worked on such as high, railway crossings, etc. Instead, a boring machine is used to bore a several inches diameter hole underneath the surface Craig Kimbrel Jersey , a duct is pulling through the hole and then fiber cables pulled into the duct.Important factors:1. Cable installation depth: up to 40 inchesThe depth that fiber cables should be buried is determined by the soil conditions and surface usage. In colder areas, fiber cables are typically buried below the frost line to prevent the cables from being damaged by ground frost heaves.2. Keep the trenches as straight as possibleFiber cable trenches should be straight, and the trench bottom should be flat and level. Backfill can also be used to distribute the cable load evenly and protect the cables.3. Fiber cable warning labels should be buried directly above the cableFiber optic warning cables are typically buried directly above the cables to warn future digging operations. Or concrete slabs can be buried below the warning label but above the cables to provide even more protection.4. Whenever conducting armored fiber cables are used, they should be .
