I want to know:
How much does Fiber Optic connection cost?
Thanks.

SYN ACK said:fiber is just a transport medium, guys.
just cause you have "fiber" doesn't mean yer going faster than your current cable connection. unless you pickd up a sonet connection >_> <_<
Dawizman said:Well, verizon has begun running its fiber lines and if I remember the prices corectly, it can range anywhere from about $40/mnth - $100/mnth in the cities where the service is avaliable.
But it's fiber..it must be faster becuz it is at the speed of light.

Incorrect. SDSL is full-duplex, as is ADSL and every other xDSL I know of.draconius said:your sdsl is not full duplex, so if you are uploading and downloading, your speeds are halved (if you have 1mbit sdsl...you max out at 512up and 512down simultaneously)
draconius said:how fast is your sdsl?
a T1 is 1.544Mbit/s full duplex (you can do a meg down and up simultaneously)
your sdsl is not full duplex, so if you are uploading and downloading, your speeds are halved (if you have 1mbit sdsl...you max out at 512up and 512down simultaneously)
Fiber services can come in many many different levels, from "true" OC level fiber serivces, to regular ethernet over fiber with speeds that are completely variable based on whatever your ISP wants.
Then you have the effective equivalent of a T1. Faster connections are available by many different means (cable, dsl, and fiber can all go faster -- see the post above about how "fiber" is just the physical interface, not a speed indicator).Which Ones said:i have 1.5mbit up and down!!
so..which one is faster?
Vanskater said:a 1.54Mbps/1.54Mbps Sdls connection would be slower then a T1
not by much mind you but this is only because fiber operates at light speed
WTF? 1.544Mbps === 1.544Mbps, period. I don't know what this "light speed" nonsense you're quoting is. Simply put, propagation speed (your "light speed" reference) has no direct bearing on data transmission rates.Vanskater said:a 1.54Mbps/1.54Mbps Sdls connection would be slower then a T1
not by much mind you but this is only because fiber operates at light speed
Vanskater said:ethernet is 2/3 the speed of light
so unless your transfering something faster then 2/3 the speed of light then you wont know the diff

No. S/A is symmetric / asymmetric. That is, upload == download or upload != download. They're both full duplex; both upload frequency bands are completely separate from download bands.SYN ACK said:SDSL is synchronous, and thus, upload speeds do not effect download speeds.
ASSL is asynchronous, and thus, acts likes cable modem where if you are uploading something, it will effect your downstream.
Otherwise, yes, agreed
wrong again. "A" in ADSL is "asymmetric" not "asynchronous"SYN ACK said:I didn't say it wasn't full duplex.
I'm saying, in a synchronous implementation, upstream is completely segregated and has no effect on downstream, and vice versa.
Not true with asynchronous DSL / cable modem
Which Ones said:where you live?
I can't find the fiber service in www.surewest.com ??
is it fast? Currently I have one connection for SDSL for hosting my Servers, FTP, Mailserver, and other crap.
Is Fiber Service faster or T1?
WesM63 said:I think everyone pretty much covered nearly everything in this post lol.
Full Duplex means data can be transferred in both directions simultaneously and not be affected by each other.
I love it when people call in and they tell me they have the fiber connection, i nearly roll laughing. Little do they know we (ISP) don't even have a fiber connection. We have fiber to our demark then to high speed serial to our UBR router.
I think what people are trying to get at with the "speed of light'" thing is that, it can potentially carry data at the speed of light, however, we are only able to utilize it to 10gbps.
OT: I found online OC-192 (10gbps) costs $8750month. Which is BS our DS-3(45mbps) is going to cost us $8000month.

DSL/ Cable have fully isolated upstream & downstream channels; therefore, full duplex. You are trying to refer to uplink saturation which results in slowdown at a higher (TCP) network layer and affects SDSL the same as ADSLthe same as any other connection.
full duplex, by definition, is separated uplink/downlink. half-duplex is, by definition, non-separated uplink/downlink. So claiming SDSL differs from ADSL in this regard is saying that one is not full duplex.SYN ACK said:i never said it wasn't full duplex.
SDSL from my experience is not affected by upstream saturation
