@licson 如果我用qsfp分四條sfp+ 果四條sfp喺咪可以插落唔同server當adhoc lan用
pm 05:06:22
Licson Lee
唔係 adhoc...
pm 05:06:37
Licson Lee
你講緊網卡？
pm 05:06:41
Licson Lee
定係 switch
pm 05:06:53
Stefan | ᕕ(◠ڼ◠)ᕗ
HPE544+
pm 05:07:01
Licson Lee
唔得
pm 05:07:08
Licson Lee
淨係得 Intel 卡得
pm 05:09:32
Stefan | ᕕ(◠ڼ◠)ᕗ
咁應該無得慳咗switch價錢😔
pm 05:10:08
Licson Lee
唔好慳呢啲嘢啦 🙃

is tg down
pm 05:25:45
Licson Lee
驚乜嘢
pm 05:26:02
Mark
…你諗住真係物理咁拆4支lambda 就會work?
pm 06:23:45
Licson Lee
tplink 會嘈得去邊 🙂
pm 06:23:46
Licson Lee
40G SR4 好啲嘅 係四條同 lambda
pm 06:23:46
Licson Lee
每條 Signalling 同 10G 用嘅一樣，所以可以直接插 最緊要係隻 switch support 就得 🙈
pm 06:23:46
Licson Lee
400G breakout 做 4x100G 先瀨野
pm 06:24:41
Licson Lee
100G SR4 本身就要四條 25G singal
400G 變 4x100G 要用 single lambda 100G
pm 06:26:23
Mark
都係搵Muxponder 個啲拆返佢出黎🤐
pm 06:27:06
Licson Lee
LR 都係 4 條 只不過唔同 lambda
pm 06:27:23
Licson Lee
啲 100G 手指點解仲係咁貴
pm 06:27:46
Licson Lee
一條 100G LR 四千幾
pm 06:28:07
Licson Lee
都出咗咁耐
pm 06:28:10
Mark
慢慢等下啦

Licson Lee
之前問 100G CFP2 要 6000 😅
pm 06:28:57
Mark
SR4可能會平到
pm 06:29:08
Mark
但要單支100G就…
pm 06:29:38
Licson Lee
通常手指買親最少買一打嘅我
pm 06:29:47
Licson Lee
咁就好貴下 😅
pm 06:32:13
Licson Lee
跟住有條友就叫我用 CWDM4 平啲二千幾一條，但係我要用嚟行 metro...
pm 06:32:48
Mark
1.25G metro囉🤐
pm 06:33:25
Mark
或者搵dowslake 10G
pm 06:34:27
Mark
100G嘅metro 就…..swdm 16都可以諗嘅
pm 06:35:12
Licson Lee
🤔
pm 06:35:44
Mark
唔知你啲metro要幾快鳥
pm 06:35:51
Licson Lee
wow SWDM 第一次聽
pm 06:36:22
Licson Lee
100G 阿 🙈
pm 06:36:29
Mark
咪又係加強版cwdm lol
pm 06:36:45
Mark
咁dwdm la🤐
pm 06:37:19
Mark
有錢嘅話😝
pm 06:37:48
Licson Lee
swdm 咁得意嘅
pm 06:37:57
Licson Lee
WDM on MM fibre
pm 06:38:15
Mark
SM 黎
pm 06:38:55
Licson Lee
http://www.swdm.org/
pm 06:39:00
Licson Lee
我以為係呢個？
pm 06:39:50
Mark
唔是
pm 06:39:58
Mark
另一樣野
pm 06:42:57
Mark
不過，如果100G traffic嘅話，你真係玩偷雞嘅，頭尾100G,然後拆4支25或者10支10G,再笠cwdm 16
pm 06:43:24
Mark
咁應該唔洗去到LR
pm 06:44:16
Mark
係靠transmission level偷雞
pm 06:44:35
Licson Lee
咁都係正常 100G LR 算 😂
pm 06:45:14
Mark
貴呀嘛🤐
pm 06:45:16
Licson Lee
Traxcomm 啲平 dark fibre 嚟
pm 06:45:41
Mark
唔係咁你要買幾多甩100G LR
pm 06:46:07
Mark
如果拆返做咁嘅cost又幾多
pm 06:48:18
Licson Lee
平平地買部行到 25G 嘅豬扒都要幾萬 🙈
一部 CWDM Mux 一萬左右
pm 06:48:26
Licson Lee
仲有 CWDM 手指
pm 06:49:31
Licson Lee
咁同買一打 100G LR 差唔多 🌚
pm 06:50:31
Licson Lee
如果用 10G 手指可能會平啲
pm 06:50:38
Licson Lee
但係就冇乜意思
pm 06:51:53
Licson Lee
yes
pm 06:52:04
Licson Lee
你都係乖乖哋買部 switch 仔
pm 06:53:30
Stefan | ᕕ(◠ڼ◠)ᕗ
如果係ST5008F買邊隻dac好 聽講兼容性好差
pm 06:54:42
Licson Lee
好似無所謂喎 係記得買 v2 版就得
pm 06:55:10
Licson Lee
第一版有問題唔插得 10G LR 唔係塊板會燒
pm 06:55:25
Licson Lee
（雖然 v2 都麻麻地插得 LR optics）
pm 06:55:42
Licson Lee
總之唔好插 LR/ER/ZR 就無事
pm 07:54:46
Licson Lee
又或者你去買 Mikrotik CRS309
pm 07:55:06
Licson Lee
咪唔怕 TP-Link 啲 Hardware 版本問題
pm 07:56:38
Stefan | ᕕ(◠ڼ◠)ᕗ
2790...
pm 07:58:39
Licson Lee
算平啦
